Program code mismatched with the circuit diagram

Opened this issue 2 years ago · 3 comments

There are a few issues found:

PICO_SCANVIDEO_COLOR_PIN_BASE is set to 2 but the circuit diagram is 0.
In the circuit diagram, bits in a video byte is R3 G3 B2. But some of the program code is R3 G2 B3 (rgb[0] to rgb[8]) or B3 G2 R3 (rgb[9]-rgb[15].

Thanks for the report, I'll try and take a look at it soon. It is possible that the code and schematic are out of sync...

For the 2nd issue, I tried to fix with PIN_BASE = 0. And make changes to rgb arrage to B2B3R3 format and it works.

Your project is so great for me to learn PICO! Great work!

After more study and experiments made, I guess PIN 0 and PIN 1 are for stdio (standard I/O, serial in/out for debugging). So, it needs to change the program for GIO assignment rather than the circuit diagram.
