SPI issue keep getting 0 values from accelerometer

[NicRoberts]

NUCLEO-WB55RG communicating via SPI1 to an ADXL362 eval board
I set up the project (attched below) using CubeIDE, generated the code & placed my own callbacks for the SPI in main.

When I look at the value for the Z direction I should be getting a value that indicates roughly 1g but all I get is 0. The same for all the other axis, no change in any value no matter how I orient the sensor.

To check that the acceleromter was working I hooked it up to an Arduino using a 3rd party library especially for the ADXL362. That all worked as expected, so I know the accelerometer is working.

When I go through the code with the debugger it doesn't hang anywhere so I'm guessing my callbacks are working, its just I dont get any data back, all values remain at 0

Anyone see anything obvious that I'm doing wrong?

Check if Arduino Library is doing something to initialize/start the accelerometer. I remember the Bosch devices needing a quick magic sequence and scale selection. 

Get a scope or logic analyzer on the pins and review working and non-working signals.

Link to github library for working driver you're using / attempting to port

The Arduino library I used Winkelict ADXL362 Arduino library 

The only thing I've spotted is that they do is a soft reset first, which I've now added to ADXL362_Init()

SPI_WriteRegister(ADXL362_SOFT_RESET, 0x52);
HAL_Delay(500);

Which doesn't change the behaviour, I still get 0 readings.

I changed the power control register to disable auto-sleep and remain in measurement mode

SPI_WriteRegister(ADXL362_POWER_CTL, 0x02);

Still no readings. So I decided to check if I could even read the chip ID, I cant I just get a value of 0.

To prove basic SPI comms, can you successfully read the Device ID register ?

As @Tesla DeLorean said, use a scope and/or logic analyser to verify comms - compare & contrast with the Arduino.

Have you checked the AD Product Page:

Not even getting the device ID. 

Yes I have the device datasheet with the register map & the SPI settings.

As soon as I get a working scope I'll check the comms.

Sorry I should add, the example software doesn't include the hardware specific SPI drivers & I have zero experience with no_OS
