Werk
I am building a stand alone AQ unit for a friend but cannot get the LCD to display anything.
I have changed the display, (it works on another unit if i change the address in the software to suit) but not with the new build.
I have not installed the Tx socket or Tx unit and LED.
Code is attached
Regards
Jim
