MD2, MD1, MD0 Protocol Details 0,0,0 UART 2400 baud 0,0,1 UART 4800 baud 0,1,0 UART 9600 baud 0,1,1 UART baud rate in EEPROM 1,0,0 TWI address: 0x48 1,0,1 TWI address in EEPROM 1,1,0 SPI 1,1,1 specified in EEPROM specified in EEPROM Connector J1 is used for SPI communication. Connector J2 can either be used for UART or TWI communication. Connectors J4 and J5 can be used to daisy chain other TWI devices. Power Supply Options The module is rated for external power ranging from 2.7 to 5.5 volts DC. Using voltage outside this range could damage the PmodCLS and connected devices. The PmodCLS can be powered through the board’s 6-pin headers J1 or J2, or through connectors J6 or J7. When the module is connected to another Digilent microcontroller or FPGA board, that board can power the PmodCLS through a Pmod connector. The host board should be jumpered to provide 3.3V on the VCC pin of the connector being used. The module is then powered by the host board’s power supply. Instruction Set The PmodCLS is capable of executing many different instructions. Instructions are sent using escape sequences. An escape sequence begins with the ESC character (character code 0x1B or decimal 27), followed by the left square bracket ‘[‘ , followed by 0 or more parameters separated by semicolons ‘;’ and ending with the command character. Command characters are case sensitive.
