Create firmware for ADXL345 #41
Description
Our current firmware allows an ESP32 and ADXL355 to communicate. However the ADXL355 is expensive.
The ADXL345 is readily available and very low cost. For users to get started with a very affordable sensor, perhaps simply an esp32 dev board wired to an ADXL345, we should provide an option in the firmware to replace the accelerometer.
Whilst the ADXL355 is a much better accelerometer, it shares many characteristics with the ADXL345 (FIFO size, startup routine, etc) which should make swapping it out doable.
