At this point, `--stack-size 8kb` is required during the build. From my tests on `rp2040-zero`, everything except `RGB` seems to be working fine. @PercyJW-2

I think defining `drivers.Pin` is a very good idea. Except for the `examples/` directory, `machine.Pin` should be completely replaceable.

When using TTF fonts around the size of 12pt, the lack of anti-aliasing reduces font readability. Therefore, the current implementation uses 2-bit color. The current version assumes a white background...

@ehime-iyokan The GPIO of the RP2040 might be too fast. Without adding time.Sleep(), the pulse width is 110ns, which might be too short. With time.Sleep(), it is around 5us. I...

Including other parts as well, it is better to use `delay.Sleep()` for microsecond sleeps. I think it would be good if you could create a Pull Request with that change....

GOROOT and GOFLAGS are automatically set when running the tinygo command, so you don't need to configure them yourself. In general, it's better not to set them.

@jespino How was this part when you were developing it? It seems that writing to the `atmega32u4` on an `arduino-leonardo` removes the `USBCDC`, making recovery difficult.

The BLE connection is not completing because the system is not responding correctly to requests from Windows OS and other sources. Some processes related to LESC are not yet implemented...

I tried flashing your code onto the Feather nRF52840. It seems to be working correctly on my board. 

Does the issue still persist?
