[FEATURE REQUEST]Add ADXL345 accelerometer for input shaping

[ilbossdelfaidate]

If it is possible to add an adxl345 accelerometer (even just among the plugins) to calculate the resonant frequencies of the printer to be inserted in the input shaping parameter

this is for Klipper - right ?
I do not support Klipper so far because it is already connected to powerful MCU that can have network

[ilbossdelfaidate]

I meant to add the accelerometer to the esp8266/esp32 pins to make it calculate the resonant frequency for marlin only on request

[luc-github]

I did not know Marlin can use Input Shapping based on accelerometer

looking at : https://github.com/Seeed-Studio/Accelerometer_ADXL345
It use Wire and current Lua implementation does not it - I did not expect to go so far
Which means need to be part of main code of ESP3D

I do not have any device neither clear user case so PR are welcome

in marlin you can use the input shaping by inserting the resonant frequency values ​​and the dumping ratio directly from the menu, I meant if it is possible to create a plugin for esp 3d connected to adxl345 that calculates these values ​​independently from marlin and then inserts them either via M codes or the user manually inserts the values ​​into the printer

esp3d does not have pluggin feature only lua scripting feature
