If we find a way to replicate MazdaRacerDude's libusb connection via m3 toolchain (which is a bottleneck I'm working on for two other applications), that could be possible.Hi,
i was thinking about an app for the display. I thinkg that is not so difficult to implement. A sort of color picker (color palette) that can allow to chose a color and send that color to an arduino (wemos d1 mini) over wifi and turn on the ambient lights inside the car. What do you think about?
The second bottleneck then is the question, can a CASDK app write a oneliner to "/tmp/mnt/data_persist/dev/bin/"? Then the app could allow you to pick a color, store the color code in that oneliner file and the microcontroller at the usb plug could look for a change every second, read the color code and drive RGB LEDs.
For that first problem, we'd need someone who could help/explain how to flash that code from MazdaRacerDude onto a RedBear Duo or Arduino Due (should work, it also has a ARM Cortex-M3 chip). Or if possible, other (easier?) ways, maybe even on other microcontroller boards?
