Hi everyone,the pin PB_4 seems to be used by any other function. This might be due to the on board WiFi module.Does anyone have the same trouble to use this SPI conectors of the discovery board? How could I solve this?Best Jens

Hi everyone, I am trying to connect my STM32F413 Discovery Board to a MAX30003 ECG but without any success. So I checked the SPI signals with a scope and discovered that I measure a signal on the MISO line as soon as I use a write command. All pins (...

On this board there seems to be no additional SPI Pins available at the Arduino headers. But pulling up the WiFi_SPI_CSN pin (PG_11) solved my problems.Thanks to Clive and Jan,Jens

Hi Cleve, Jan,thank you again!I just bought an Nucleo f413ZH board and my SPI test program just works fine on it. So the issue is due to the many features, as you have already mentioned. My problem is that I am just a beginner to all this and I am no...

Hi Jan,I have double checked that I probe PB_4. Furthermore it is no problem to use it as a normal GPIO output without any strange behavior.This signal at the MISO pin only (but constantly occurs) when I use “write�? from Class “SPI�?.Any hint would ...

PS: When I try to use other SPI pins, I receive a pinmap mis-match error so that i can't change them.

32F413H-DISCO: communication problem with SPI MISO pin PB_4

SPI (Basics): Why do I get a signal at MISO (PB_4) when performing a write without any connection to this pin? I am using STM32F413 Discovery Board with mbed
