I just finished building the Eggfinder LCD. Everything seemed to be ok until I tried to power the unit up. All I get is solid black squares across the LCD display, no beeps from the buzzer either. I went back and touched up all the solder joints thinking I might have a bad connection. Still no signs of life. I even hooked up the data cable to the USB port on my PC. I can see “prolific” on COM3 is active.
Any suggestions what to try next?
Thanks, Pete
