    Hello!

    I got the an972 software from the ST page. I have been tried to probe it. I´m using the ST72f324 MCU for it. In the software it is initializing the PC4 (float input), PC5 and PC6 (outputs PP) ports but when i debug the program or when i run it, the ports sets are PA5 and PA6 (never initialized in the program). I don´t understand why it is happening. I undertand that program is an emulation for the SPI Master, the registers for the the SPI are not configured in the program they seems like standars I/O. Could you tell me what is happenning please and suggest to me where i can look for the real configuration of the SPI Interface.

    Thanks!

    One can not debug SPI code on the ST72F231 because the debug program uses the SPI ports for communications.

    Maybe, you are having same problem with your device.

    Good luck,
