STSAFE-A100 reference manual for driver development?

[UHida.1]

We are working on rust based driver development for

STSAFE-A100. we couldn't find any reference manual for the same, Is there any NDA? If not could any one share resources required for driver development in rust?

Hi @UHida.1​ 

You will find the C driver example in the following package : https://www.st.com/content/st_com/en/products/embedded-software/mcu-mpu-embedded-software/stm32-embedded-software/stm32cube-expansion-packages/x-cube-safea1.html

You can have a look in the stsafea_service.c file to check the overall protocol.

What I can tell you is that the STSAFE-A is using frame based protocol over I2C, therefore you need low level I2C driver that support this mode.

Best Regards,
