@crami25 Thanks for the comprehensive reply. It really helps to deepen my understanding. As you pointed out, I always check the M5 Unit's schematic first to assure the protective resistors when I connect the Units to an ESP developing board.
Hello. Please tell me if there is a UnitV circuit diagram? Or, by analogy with other modules, a description of which components, to which GPIO are connected. For example, the GROVE connector is connected to gpio xx and yy, the camera is connected to "...", the buttons are "..." and so on.
@ss4f11 If you had mentioned this previously, sorry, my memory isn't that great.
I need to look into finding a walkaround for that for my book but again it on my "To Do" list.
It must be high clock issue on PAHUB. I just tried to hide Wire.setClock(450000) and change the refreshrate of MLX90640 to 4Hz (0x03). It worked well. With PAHUB, it cannot work with high refreshrate (E.g. 8Hz or 16Hz)!!!
@rupin-chheda as far as I know it is not documented how much current it can source, all I can say that I have tried various things and keep getting “device not connected “ when it is connected. This is a sign that the device isn’t getting enough power.
