Hi to all,
Trying to connect a mega 2650 to a 1602 lcd display without success.
Using I2C address of 0x27 and port speed 9600 which is correct for my display. connected SCA to pin a5 and SDA to pin a4
Library is Adafruit_FRAM_I2C and sketch "Hello World"
Have adjusted backlight so can see pixel squares but when I compile and upload, compiles no problem,get message "done compiling" tx and rx lights on arduino cease flashing but all I can get on the display are the pixel squares.
I am a complete newbie and completely stuck, Anyone and ideas please, please, please.
Thanks in advance
