Ampy is fine. You may also use pyboard.py https://github.com/micropython/micropython/blob/master/tools/pyboard.py or rshell. These are both python scripts, which should work on any OS. You might have to install pyserial via pip: pip install pyserial or python -m install pip pyserial Rshell is pretty...

The uart.read() may timeout fast. In the reading loop, you should first wait by calling uart.any(), until you receive some characters, and then call uart.read(). About the connection: I assume that you connect the orange wire to 3.3V Vcc, and that the idle state of the UART line is at a high level. ...

Rotations is a simple linear transformation, which you can do in your code, like: x_new = a + b * x, where the a and b values have to be determines experimentally. Rotating by 90° or 270° would then only require to swap x and y. I cannot help you much with the calibration values, since that would re...
