RA: Set all LEDs command: EXP Bus Command Reference

Understanding EXP board addressing

This command is used with FAST Expansion and FAST breakout boards via a FAST Serial Protocol (FSP) connection to the EXP Bus. Please read the EXP Overview to understand the operation of these commands and addresses.

This command sets all the LEDs connected to all ports on a breakout board to be the same color.

RA:<RGB Color><cr>

Example:

Turn on all LEDs connected to the FP-EXP-0091 expansion board, at ID 0 (address 88), about 20% green

ea:880
ra:005500

Note this command has a 50ms timeout which cancels it if the <CR> is not received within that time.

Return Response

None
