Maybe you should connect 2 pull-up resistor on SCLK and MOSI(SDA)...I have tested it on 42MHZ(stm32f4) with pull-up resistors and it worked fine.
Thank you very much for your interest. I will test and return soon.
Again Hi,
I tested what you said. I tried tensile resistors by connecting them to 5V. The values of my resistors are 3.3K but did not work. It only works at 2MHz. Could there be a different place that I did wrong?
I am using STM32F407VGT6
Thank you very much for your interest.
Pull-up resistors should be connected to 3.3v because stm32's IO is 3.3v logic level...And you may check stm32's clock tree configuration, I'll upload a demo project based on stm32f407vet6 later
Hi,
I got a same problem. I tried to initialise on Stm32cubeIDE there is no error but also it isnt work :D
Merhaba Turgay çok güzel olur gerçekten stm32f405 ve stm32f407 kullanıyorum ve slave pinini kendim yapılandırmak istiyorum

Melih Merhaba,
Hangi denetleyiciyi kullandın ? Ve bende bunun yazılım üzerinde bir kaç revizyon yaparak düzelttiğim versiyonu var bakmak istersen gönderebilirim.

Merhaba Turgay,
çok güzel olur gerçekten... stm32f405 ve stm32f407 kullanıyorum ve slave pinini kendim yapılandırmak istiyorum.
Hi,
I have tested your code but it only works with SPI 2MHz. Is there any place you can help?
