WARNING: Care should be taken to prevent power sourcing conflicts. Table 2 shows valid jumper settings. Other settings may be possible, but must be evaluated for a specific application. One example of an invalid configuration is when JPC is shunted, and the +3.3V pin on the Arduino Power Header is being powered externally by Arduino. The internally derived +3.3V and the external +3.3V will be in conflict.
2.2 Internal Voltages There are a number of voltages that can be found on the DSPShield. They are derived from various ICs and can be monitored at certain points. Table 3 lists the voltages, test points and the devices/functions powered by the voltages.

2.3 Voltage Monitoring The output voltages of the LMR10510X DC-DC (+3.3V) regulator and the LP3982 (+1.3V) LDO regulator are monitored by a TPS386596L33 Quad Reset Supervisory IC. If either voltage drops below certain thresholds, the TPS386596L33’s active low open-drain reset output will go low and reset the C5535 DSP and the DSPShield. The TPS386596L33 has a 50 msec delay time from the time all sense inputs are valid to the reset output becoming inactive.
2.4 C5535 DSP Core Voltage The C5535 DSP’s +1.3V Core Voltage, CVDD, can be driven either by its internal LDO or by the LP3982 LDO. The selection is accomplished by populating certain combinations of resistors R25, R26, R27 and R28. The two options are listed in Table 4. CVDD = C5535 DSP_LDOO (DEFAULT )
R25 = DNI R26 = 0 Ohm Resistor R27 = 0 Ohm 1/8W Resistor R28 = DNI
CVDD = LP3882 LDO
R25 = 10.0K Ohm Resistor R26 = DNI R27 = DNI R28 = 0.0 Ohm 1/8W Resistor
Table 4. C5535 DSP Core Voltage Selection
3 C5535 DSP and Internal Peripherals The C5535 DSP is a high-performance, low-power, fixed-point Digital Signal Processor. It has dual multipliers, dual ALUs, and a tightly coupled FFT hardware accelerator for performing math intensive signal processing algorithms. It has multiple I/O peripherals that allow it to easily connect to serial Analog to Digital Converters, Digital to Analog Converters and integrated codecs such as the TI TLV320AIC3204 Audio Codec.
3.1 Parallel and Serial Peripherals The C5535 DSP’s internal External Bus Selection Register (EBSR) determines which of the following: LCD controller, I2S0, I2S1, I2S2, I2S3, UART, SPI, MMC/SD and GPIO signals appear at the chip’s multiplexed GPIO pins. These peripherals can be grouped into 3 groups as shown in Tables 5a, 5b and 5c. For each group, only one mode of operation is available at a given time. Note that the DSPShield architecture further limits

3.2 Clock Sources The C5535 DSP has 3 input clock sources: the USB_MXI pin, the CLKIN pin, and the internal Real Time Clock (RTC). The USB_MXI input is connected to a 12 MHz oscillator and is the clock source for all USB peripheral activity. The CLKIN input is also connected to a 12 MHz oscillator while the RTC is connected to a 32.768 KHz crystal. Either CLKIN or the RTC can be the reference source for the C5535 DSP’s system clock generator. Resistors R8, R9, R10 and R59 select the source as shown in Table 6. The different clocks within the system clock generator block can be output on the C5535 DSP’s CLKOUT pin and monitored at Test Point TP1. System Clock Generator Reference Source

3.3 ROM Bootloader The C5535 DSP has an on-chip ROM Bootloader (RBL). It samples the following interfaces, in order, looking for a boot signature: SPI EEPROM, I2C EEPROM, MMC/SD0 AND UART/USB. Once a boot signature is detected, the C5535 DSP will download the boot image and then jump to the entry point specified in the image. For the DSPShield, the SD0 peripheral connected to the micro SD Card connector is the default boot source. Figure 4 shows the RBL Software Architecture from the C5535 DSP datasheet.

3.4 /INT1, /INT0, XF, WAKEUP The C5535 DSP’s /INT0 input is routed to the DSP Expansion Connector. It has a pull up resistor. The C5535 DSP’s /INT1 input is connected to the I2C to GPIO Expander ICs’ /INT outputs. The interrupt outputs of the 2 Expanders are open-drain and are wire-ORed together with a pull up resistor. The C5535 DSP’s XF output controls the LED, D2. A logic “1” turns on the LED. The C5535 DSP’s Wakeup pin can be monitored on Test Point TP2.

Arduino connector, the I2C bus is buffered by a TI PCA9515B I2C Repeater IC. The IC provides a translation between the Arduino’s IOREF logic levels and the C5535 DSP’s +3.3V logic levels. On power up and reset, the PCA9515B is disabled. This isolates the DSPShield’s internal I2C bus during the boot sequence. After boot, the C5535 DSP can enable the PCA9515B by setting DSP_I2C_EN on Port0.2 of GPIO Expander 2 to a “1”.
4 DSPShield Peripherals In addition to the C5535 DSP’s internal peripherals, the DSPShield has several external peripherals that increase its functionality. The peripherals are:
1. Two TCA6416A 16-bit I2C to GPIO Expander chips 2. OLED display 3. TLV320ACI3204 Stereo Audio Codec 4. Micro SD Card connector 5. DIP Switch Inputs, LEDs, and Push Button Reset 6. Additional peripherals can be added through the use of the 40-pin DSP Expansion
Connector and the Arduino Interface Connectors.
4.1 I2C GPIO Expander The two TCA6416A (I2C to GPIO) Expander chips increase the number of GPIOs under the C5535 DSP’s direct control. Each chip provides an additional 16 GPIOs. Tables 8a and 8b list the direction (after programming) and function of each GPIO. On power up and reset, all the GPIOs are initialized as inputs. Some GPIO pins have external pull up or pull down resistors connected to them that allow the various DSPShield external peripherals to power up in a known state. For example, the U3 4-bit 1to2 multiplexer’s select pin is connected to Expander 2’s Port0.4 GPIO and also to a pull up resistor. On power up and reset the C5535 DSP’s I2S lines are multiplexed to the codec. To prevent glitches during initialization, the following sequence should be followed to program output pins.
1. Program the Expander Output Port Registers to the default values listed in tables 8a and 8b.
2. Program the appropriate direction bit in the Expander Configuration Registers for GPIOs that will be outputs.
3. After initialization, the Output Port Registers can be changed depending on the application.

The GPIO Expanders also have an open drain active-low interrupt output. The interrupt outputs of the two GPIO Expanders are wire-ORed together and connected to the C5535 DSP’s /INT1 input. An interrupt is generated by any rising or falling edge at the port pin when programmed as an input. Resetting the interrupt is achieved when the data on the port is changed to the original setting or when data is read from the port that generated the interrupt. This interrupt feature of the GPIO Expander is very basic and lacks an interrupt mask capability. NOTES:
1. There are no external pull up or pull down resistors on GPIO pins that can be programmed as input or output. If unconnected, these unused GPIO should be programmed as an output to avoid floating inputs. The output value is irrelevant, but a logic zero is preferred.
2. Expander 1 GPIOs use IOREF to select the correct logic levels depending on the state of jumpers, JPD and JPE. Expander 2 GPIOs use +3.3V logic levels only.

4.3 TLV320ACI3204 Audio Codec The TLV320AIC3204 Audio Codec interfaces to the C5535 DSP via the I2C and I2S2 buses. The C5535 DSP’s I2S2 Bus is routed to the AIC3204 when I2S2_MUX_SEL = 1. The AIC3204’s I2C address is 0x18. The microphone stereo input is routed to the Pink jack, J1. The head phone stereo output is routed to the Green jack, J2.
4.4 Micro SD Card Connector Controller SD0 is connected to a micro SD card connector, P2. The micro SD card is the default boot source for the C5535 DSP’s on-chip ROM Bootloader (RBL).
4.5 DIP Switch Inputs, LEDs and Push Button HW Reset The status of switches 1, 2, 3 and 4 of DIP switch SW1, can be read by the C5535 DSP via Port1.7, 1.6, 1.5, 1.4 of the GPIO Expander 2, respectively. The “ON” position corresponds to a logic “1” in the GPIO Expander Input Register. Three general purpose status LEDs are available for display by the C5535 DSP. They are controlled by the output value of Port0.0, 0.1, and 0.6 of GPIO Expander 2. They correspond to LEDs labeled as LED0, LED1 and LED2 on the board. A separate LED is tied to the C5535 DSP’s XF general purpose output pin. It is labeled LED-XF on the board. Writing a logic “1” to the appropriate registers will turn on the LEDs. A manual reset is provided by push button SW2. Pressing this switch will place the DSPShield in its default state.

The FT2232H has two channels. When connected to a PC with the appropriate software drivers installed, one channel will enumerate as a TI XDS Emulator and the second channel will enumerate as a generic USB serial port. Once the PC connection is established, the XDS_LED will turn on. The XDS100 channel is connected to the C5535 DSP’s JTAG inputs and the serial port channel is connected to the C5535 DSP’s UART interface. The serial port channel includes the data signal pair TXD/RXD, and the flow control signal pair, RTS/CTS. If not used for flow control, the FT2232H’s second serial port RTS pin can also be used as an external reset source for the DSPShield (see Section 6.2). If RTS is being used for flow control, the external reset can be driven by the FT223H’s DTR pin by removing R161 and installing a 0 Ohm resistor on R163. RTS is the default emulator reset source for the EmuResetSrc signal. On power up, RTS and DTR are tri-stated and a pull up resistor holds EmuResetSrc at a logic “1” level. Since RTS and DTR are defined as active low signals, RTS and DTR will remain high after USB enumeration. A PC can reset the DSPShield by toggling EmuResetSrc, (RTS or DTR) signal High to Low to High.
5.2 Power via XDS-USB It is possible to power the DSPShield via the XDS_USB connector. See section 2.1. The FT2232H itself is powered by the +3.3V from VR1. It also has an internal Power-On Reset that is independent from the DSPShield’s board level system reset.
6 Arduino Interface The DSPShield has a standard Arduino Interface on connectors P5, P6, P7, P8 and P10. The connectors are 0.1” pitch female receptacles with long 0.025”sq tails. The long tails for P5, P6, P7, and P8 on the bottom side allow the DSPShield to stack on top of an Arduino board and at the same time repeat the Arduino signals on the top side. The ICSP connector, P10 is similar except that is mounted with the female receptacle on the bottom. The Arduino connector signals are grouped by function and are defined in Tables 10a, 10b, 11c, 10d and 10e. Pin Signal Name Direction Function

6.1.1 Interface Logic Levels In Stacked Mode, the DSPShield is compatible with +5V and +3.3V versions of the Arduino family of uC boards because it uses the Arduino IOREF pin to power the DSPShield’s Arduino buffer circuitry. In Stand-Alone mode, the DSPShield uses internally derived +5V or +3.3V to source the IOREF pin as well as power the buffer circuitry. The voltage supply for the buffer ICs that interface to the Arduino can be programmed via jumpers JPD and JPE. Table 11 lists the different voltage sourcing configurations for the interface buffer ICs. WARNING: The Arduino buffer circuitry must be powered either by IOREF or by internal power. One of the entries in Table13 must be implemented.

6.1.2 Analog Inputs The four analog inputs from the Analog Connector are routed to the C5535 DSP’s GPAIN[3:0] inputs. The analog signal magnitude must be limited to 0 to +1.3V. For protection there are 100K Ohm series resistors in the input path to limit the input current. They can be replaced with a different value for specific applications. Additionally, there are Schottky diodes for clamping the voltage swing to between GND and +1.3V. However, it is recommended to use an input buffer circuit that will limit the input voltage swing by design. If the Arduino Analog Header is being used only in a pass through mode, it is recommended that the input series resistors be removed. This disconnects the C5535 DSP from the Arduino Analog Header and will allow the Arduino Analog pins to safely pass signals up to 5 volts without damaging the C5535 DSP.

The multiplexing circuitry is controlled by the signals RST_CNTRL[1:0] in GPIO Expander 2. Some Common multiplexing configurations are listed in Table 12. On power up or when push button switch SW2 is pressed, the GPIOs of Expander 2 are configured as inputs. Until they are programmed, the external pull down resistors will maintain the Reset multiplexing circuitry in the default state.

Table 12. Arduino/DSPShield Reset Multiplexing Control
6.2.1 Default Configuration In the default configuration, the DSPShield is sensitive to the state of the ARD_RESETN pin on the Arduino Digital Connector. Either the Arduino or the Emulator can reset the C5535 and DSPShield by applying a logic “0” to the ARD_RESETN pin. See Figures 8a and 8b.
6.2.2 C5535 DSP Self Resets In this configuration, the C5535 DSP generates a logic “0” that is routed to the ARD_RESETN pin and also to the DSPShield’s reset circuitry. This is a “circular” reset that will cause the C5535 DSP to reboot. See Figure 8c.
6.2.3 C5535 DSP Isolated from ARD_RESETN In this configuration, the DSPShield is disconnected from the ARD_RESETN pin. Only the Emulator EmuResetSrc or the hardare push button can reset the DSPShield. See Figure 8d.
6.2.4 C5535 DSP Resets Arduino In this configuration, the DSPShield’s own reset input is isolated from the ARD_RESETN pin. At the same time it drives a logic “0” onto the ARD_RESETN pin and therefore resets the Arduino. See Figure 8e.
6.2.5 Emulator Resets the DSPShield Exclusively There may be some application that requires that the emulator be able to reset the DSPshield without resetting the Arduino. In this case, by switching R119 and R122, the EmuResetSrc signal is isolated from the ARD_RESETN pin. See Figure 8f.
6.3 DSPShield UART Multiplexing The C5535 DSP’s UART peripheral can be connected to the DSP Expansion Connector, Arduino Digital Header IO0 and IO1 pins, or the Emulator secondary serial port. The multiplexing of the UART signals are controlled by UART_MUX_SEL and UART_CNTRL[3:0] via the GPIO Expanders. Table 13 lists the 4 multiplexing modes used in most applications. The different UART Multiplexing Modes are listed in Figure 9. UART_ MUX_ SEL Expander 2 Port0.5

However, some control signal combinations may cause bus contention on the Arduino IO[1:0] connector pins due to multiple tri-state buffers being enabled at the same time. Please refer to Figure 9 and the schematic.

After both the Arduino uC and the C5535 DSP are operational, communication between both processors is possible by choosing the Arduino Communication Mode. The Arduino uC’s TXD line is routed to the C5535 DSP’s RXD line and the Arduino uC’s RXD line is routed to the C5535 DSP’s TXD line. See Figure 8c.
6.3.3 UART Emulator Serial Port Communication Mode When UART_MUX_SEL=0, the C5535 DSP’s UART signals are always connected to the Emulator secondary serial port. The Emulator secondary serial port’s RXD line is tied directly to the C5535 DSP’s TXD line. When UART_CNTRL0=0, the Emulator secondary serial port TXD line is OR’ed with one of the Arduino’s IO[1:0] connector pins before being routed to the C5535 DSP RXD line. Care should be taken that Arduino and the Emulator serial port are not transmitting at the same time. There is no electrical conflict, but the transmission will be corrupted. See Figure 8a and 8b. When exclusive communication with the emulator serial port is desired, UART_CNTRL0 should be set to a logic “1”. This shuts off the Arduino’s TXD signal from reaching the C5535 DSP’s RXD input. See Figure 8d. When a single chip uC based Arduino board such as the Arduino Leonardo is used, there is no direct UART path between a PC and the DSPShield for C5535 DSP code downloading. In this case, the Emulator Serial Port can be used as an alternative for this purpose. Two USB PC cables are required, one to the Arduino Leonardo and one to the DSPShield’s XDS-USB connector.
6.4 Arduino/DSPShield I2C Interface The C5535 DSP’s I2C bus is isolated from the Arduino I2C bus by a PCA9515B I2C Repeater IC. The PCA9515B provides isolation and voltage level translation. The C5535 DSP side of the IC operates at +3.3V levels, while the Arduino side operates at voltage levels determined by jumpers JPD and JPE. The I2C specification allows multiple masters on the bus. When the PCA9515B is enabled (DSP_I2C_EN = 1 in GPIO Expander 2), the C5535 DSP can operate as a master and communicate with the peripherals on board the DSPShield as well as any slaves on the Arduino side. Conversely, an Arduino can be a master and communicate with any of the peripherals on the DSPShield. For example, the Arduino master could make use of the DSPShield’s OLED Display. On power up and reset, DSP_I2C_EN = 0. This isolates the Arduino and C5535 DSP I2C buses and allows the C5535 DSP to program the DSPShield’s on-board peripherals without worrying about access conflicts with an Arduino Master.

6.5 Arduino SPI Interface The Arduino SPI interface is available on both the Arduino Digital and ICSP connectors. The Arduino uC SPI peripheral can operate in master or slave mode while the C5535 DSP SPI peripheral can only operate in master mode. The two SPI buses are connected via a TXB0104 bidirectional voltage level translator buffer. The TXB0104 provides automatic direction sensing as well as tri-state isolation capability. The control signals on Expander 2 used to control the SPI interface multiplexing are listed in Table 13. The different Multiplexing Modes are illustrated in Figure 10.

Table 13. Arduino/DSPShield SPI Multiplexing Control The C5535 DSP has four SPI chip selects, CS[3:0]. The chip selects, CS[3:1], are routed directly to the DSP Expansion Connector. CS0 is shared between the Arduino SPI SS pin on the Digital Connector and the DSP Expansion Connector. When the C5535 DSP is operating as a SPI Master, SPI_RX_SEL multiplexes the Arduino’s MISO and the DSP Expansion Connector’s SPI_RX to the C5535’s SPI RX input pin.

6.5.3 Arduino Isolated/C5535 DSP Master This configuration allows the C5535 DSP to be the sole Master of the Arduino SPI interface. DSP_SPI_EN should be programmed with a “1” and SPI_RX_SEL should be programmed with a “0”. The Arudino uC SPI pins should be tri-stated either by keeping the Arduino in reset or programming its SPI pins as inputs. See Figure 10c. When the C5535 DSPShield is in Stand-Alone mode, this configuration allows it to be the SPI master of other off the shelf “Arduino shields” or other specially designed daughter cards. One such daughter card is the TI designed “AnalogShield”.
7 Resistor Multiplexing Configurations The DSPShield has a number of multiplexing options that are controlled by resistors. The previous sections have described some of the default configurations and possible alternatives as well as control signals that can override them. Table 14 lists all the resistor combinations and their functions. The defaults describe the configuration on power up and after a manual reset. Function Resistors /

Table 14. Resistor Multiplexing Configurations
8 Stand-Alone Mode The DSPShield can function perfectly as a stand-alone development board for TI’s C5535 DSP. It can accept standard Arduino “shields” daughter cards as well as daughter cards that make use of the DSP Expansion Connector. When used in a stand-alone mode, the recommended configuration is described below:
• Power the DSPShield via the DSP-USB or XDS-UXB (shunt JPF) connectors. • Determine whether to source power to the Arduino Power Connector.
o Shunt JPB and JPC to source +5V and +3.3V on the Arduino Power connector.
o Leave JPB and JPC open if power sourcing is not required. • Determine the voltage of the Arduino connector Buffer ICs.
o Shunt JPE[1-2] for +5V logic. o Shunt JPE[2-3] for +3.3V logic. o Shunt JPD to source the Arudino IOREF pin.
• Change Resistor Multiplexing o If required, change default resistor settings. See section 7.
• Emulation Environment o TI Code Composer Studio via XDS100 embedded emulator. o Energia IDE via FTDI FT2232H secondary serial port.
