I have breadboarded the AXE133 circuit as shown on page 5 of AXE133-pmd v1.1, downloaded the AXE133 basic firmware from the PICAXE site, and programmed the 18M2, firmware version 2.B. Of course, a wiring error is possible, but I have checked it multiple times, and cannot find any errors. On power up, I get no greeting message; rather, the top row of the LCD seems to be all pixels lit, and the bottom row all pixels dark.
Any suggestions?
Thanks.
