RCP stimulator

RS232 serial output

The stimulator will output the current Analog channel data on the serial port, which can be read by the Aux Serial input of RaceCapture/Pro.

Baud Rate

Baud rate is 115200, 8N1

Format

The output format is CSV with the following columns:

• Timestamp in milliseconds
• Channel 1 value (0-10000)
• Channel 2 value (0-10000)
• Channel 3 value (0-10000)
• Channel 4 value (0-10000)
• Value echoed back from received data

Example Lua script to read serial data

--initialize Aux serial port to 115200, 8, N, 1
initSer(6, 115200, 8, 0, 1)

setTickRate(10)

function onTick()
  --write something to be echoed back
  writeSer(6, 'echo')
  --read a line from the aux serial port with a 100ms timeout
  value = readSer(6, 1000)
  if value ~= nil and value ~= '' then
    print('read value: ' ..value)
  end
end
