Does anyone use SPI on the 32F413HDISCOVERY Discovery kit?

Hi,

I got big problems with the SPI of this special board. The MISO pin (PB_4) seems to be used by any other function: I measure a constant output signal on this pin as soon as I use a write function (the pin is not connected, a pulldown or pullup doesn't change this signal).

Does anyone have a simple code using this SPI ?

Thanks to all, Jens

Hi

The PB_4 pin is connected to the WIFI module.

You can have a look in the PeripheralPins.c file to see all the available pins and conflicts with other components available on the board.

For example here: https://github.com/ARMmbed/mbed-os/blob/master/targets/TARGET_STM/TARGET_STM32F4/TARGET_STM32F413xH/TARGET_DISCO_F413ZH/PeripheralPins.c
