Activate RS-485 second port on LM5 lite
#1
Hi,

I need to use 2xRS485 on LM5 Lite.

on RS485-1 all is working, but on RS485-2 not. (seems to be using rs232)

Script:
if not port then
  require('serial')
  port = serial.open('/dev/RS485-2', { baudrate = 9600, parity = 'even', duplex = 'half' })
  port:flush()
end

if port then
  char = port:read(1, 1)--send back if read succeeded
  if char then
      port:write(char)
  end
end



Tnx. Auzzii
