Thanks for the instructions and updating the hex file! So far I have not tried to use your bootloader. I'll try and find the time to play with my new toy soon

Thanks for all your efforts Chris!

Cheers,
Harald

Edit:
Not sure if anyone commented already, but I just noticed the alpha legends on row 3 and 4 are not correct. K,L,M needs to move one key to the left, and so does O and P.
Nothing a white edding couldn't fix though

Congrats!! The keypad prints are off on 2 of the rows. Also the fact that I miss 2 traces on the back. I can re-do just the keyboard PCB and since it's within 100mm x 100mm, it will cost <$20 + $10 shipping to get 10 PCBs manufactured. I guess this is the advantage of using two PCBs.

Your photo seems to show the LCD contrast a bit off. You can turn the unit off, turn it back on while pressing "SST", and use "+" and "-" keys to adjust the contrast / bias voltage.

I had given you my old case, w/ the corner mis-formed and also the PCBs "sinks" into the case. If you wish, you can go to http://www.tinkercad.com and search for "NP41 Case", I had made it public so you can tinker w/ it and order a print (locally in your area) via 3dhubs.com. It should cost about $20.

This is very encouraging. Let me know what you think for improvements.
