Adding official support for ADXL343 and ADXL346 #5648

Closed Max-Roesenberger closed 2 years ago

Max-Roesenberger commented 2 years ago

the ADXL343 is already unofficially supported due to having the same device ID as the ADXL345. the ADXL346 has the same adresses and general functionality as the ADXL345 and is a drop in replacement exept for the different device ID. I have bodged the ADXL345.py on my printer to accept the different device ID and the ADXL346 is working flawlessly. I attached my klippy.log and my bodged python code. The bodge is adding the id of the ADXL346 in line 23 and making the code accept that id in line 375.

There seem to be some differences between the 345 and 346. See https://ez.analog.com/mems/f/q-a/81958/adxl345-adxl346 Don't know if it has an effect on the measurement. Ping @dmbutyugin

From my understanding its about the least significant bit being 0 since it falls outside the valid data range. so the 0 is just a defined state.
