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

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.
