Hi there My brother and I have in our possesion serial lcds (actually ten of them!) from Milford and we are having trouble using such an lcd with arduino.
the very helpfull support of milford wrote to us about the serial controller : '' It will receive data as RS232 format I.E. inverted, at RS232 0/9v or TTL 0/5volt levels. If you have any problems with sending data please check that the output voltage from the Arduino module is at least 4.5 vdc for the logic input, and is being sent RS232 8N1 @ 9600 baud or 2400 baud if the jumper is removed. ''
Can you please suggest a way on how to do it?
I am newbie and I am a bit lost and since we have 10 lcds it would be a waste not to use them!
