Thank you! No issue, as you told me that you were busy with some other tasks.

In the future, I will create a new ticket for assistance 🙂

Thanks & regards,

Hi JONATHAN LL

Hope you are doing well! I tried and the issue was resolved. Now I am able to read the internal registers like part # etc.

The only change in the above code pasted is to comment the

//| SPI_MODE_CPOL
//| SPI_MODE_CPHA

means make it 0.

First is clock

2nd is MOSI , 0x94 0x00 for reading part # command

3rd one is MISO , 0x0C , part number received

The last one is the CSN

thanks for the help!

Regards,

Muhammad Usman
