STM32F207 not working as SPI slave when NSS is configured in software mode.

Hello GuysI am building a very simple application using CubeMX. I am using two STM32F207ZG boards to communicate with each other over SPI bus without DMA or interrupts.One is acting as a master another as as slave. The slave settings are as follows. ...

EXTI registers

Hi,I try to write a interrupt function with registers on the stm32h743zi referans manual ,but keil doesn't recognize some registers for exp ,EXTI->CPUPR1 =(1<<13); SYSCFG->EXTICR4= (1<<5);stm32cubeh7 MCU package V1.5

Most proper way of detecting CAN BUS OFF condition?

Dear ST community,We are running a CAN network with a lot of nodes (>200) using the STM32F107VCTx chip (and MCP2551 transciever) all receiving instructions from a central linux embedded computer with a MCP2515 CAN Controller.Sometimes the nodes stop ...

DAC peripheral on STM32F407

I am working with STM32F407VG microcontroller (STM32F4 discovery board). When using the DAC peripheral for an application I was verifying the minimum and maximum voltage that can be generated from the DAC pin by providing values of 0 and 4095. Howeve...

Hello. I am a student who is studying through STM32F446. I want to real-time CAN how about them? What should I do? And do you have an example?

How to control on board ADC with SPI bus (STM32F051)

I connected a particle photon micro controller to STM32F0 discovery board using SPI bus. The photon acts as the master and STM32 acts as the slave. I understand how to code on the STM32 directly though IDE to use ADC but how to do this by sending da...

how do you move a project to a new workspace?

SPI communication between 2 stm32 boards

Hi @Community member​ i want to establish communication between the F411E-Disco as a master and the F413H-Disco as slave( so the idea is to display the temperature value acquired by the PT-100 using ADC in the the F411and then sending the value throu...

What timers are free

Cube/HAL shows some nice Timers, are they free. That is are they used by for instance HAL_Delay or something else. What about the examples and their timer usage.
