accelerometer not found DUET WIFI V1.2

ander

Hi there!
I have installed an accelerometer LIS3DSH on my duet wifi V1.2.
I was using an ethernet wiring to do the conection but the console was telling me that the accelerometer wasn´t found. I read in this forum that the wiring could be important so i changed the wire with a usb 3.0 cable.
The problem persists.
Sending the M955 P0 : Error: M955: Accelerometer not found
Here is my config.g:
config(5).g
Also, this is my wiring:

Can someone give me a hand please?
This is my M122:

I forgot to mention, the screen is telling : "accelerometer not found in specified port" when starting

@ander Your accelerometer configuration command is:

M955 P0 C"spi.cs2+spi.cs1"

Wiring instructions are here: https://docs.duet3d.com/User_manual/Connecting_hardware/Sensors_Accelerometer#wiring

Your wiring order looks incorrect, I think you have SDA and SCL wrong. It should be:

Duet 2 WiFi	LIS3DSH
+3V3	VCC
GND	GND
SPI_SCK	SCL
SPI_MOSI	SDA
SPI_MISO	SDO
SPI.CS2	CS
SPI.CS1	INT1
