RE: RPN scientific calculator firmware for $13 calculator kit
I haven't reflashed my controller yet but wanted to test the build before I do. I have a problem. When I switch modes, sometimes the first character of "Color Ring R C 5" is missing. If I change to "Color Ring R C 4" and back the C appears and stays lit. The R in Rled and the 1 in 10HEX are usually missing as well but not always. If I change from 10HEX <=> 16HEX to 16HEX <=> 10HEX and back, the first character (1) shows up as normal. I don't see a pattern to it. Does anyone else have this problem? If not what can I check? All my solder joints look OK to me.

Also, where to I connect to the board to reflash the chip?

TIA
