Confused

[jonshouse1]

I can build it, but it does not do anything on the pico demo VGA board I have:

A little help with in the readme on how to configure it would be nice, I assume the VGA pins need assigning or the video mode selecting, i've no idea how.

Thanks.

The pico demo VGA board expects R8G8B8 which is 2 bytes/pixel. But picovic expect R3G3B2 which is 1 bye/pixel. The circuit of the demo board is differed from the picovic design.

Moreover, as in another issue posted by me, the pin assignment of the circuit diagram is different from the configuration parameter PICO_SCANVIDEO_COLOR_PIN_BASE in the scanvideo/scanvideo_base.h.

It has been a long since I worked on this. It it possible that the circuit schematic is out of sync with the code. I'll try and make some time to take a look at it these next few weeks.

I download the code and change PICO_SCANVIDEO_COLOR_PIN_BASE to 0 and it works with the hardware I build referred with the provided circuit diagram. Thanks and I learnt a lot!
