Refer to this link for Klipper configuration

https://www.klipper3d.org/Measuring_Resonances.html.

The wiring in the link is directly connected to the Raspberry Pi. If you want to connect to the MCU motherboard, you can refer to the following wiring and configuration:

[adxl345]

cs_pin: PD9

spi_bus: spi1

#spi_software_sclk_pin: PA5

#spi_software_mosi_pin: PA7

#spi_software_miso_pin: PA6

1. The ADXL345BCCZ three-axis accelerometer needs to have a stable installation plane, otherwise it will affect its measurement accuracy.

2. Note that the board is powered by 5V, and 5V and GND cannot be reversely connected.
