Possible to use any I/O PIN for GPIO? (re: STM32, etc)

I'm new to micro controllers (but I have a software engineering background) and I decided to purchase a NUCLEO-F429ZI (STM32F429ZI).There are a LOT of pins on this board (168 I/O pins according to the datasheet!). However, if I just want simple HIGH/...

How can I Test CAN ( MCP2515 ) failure and reason of failure?

I am using CAN(MCP2515 Controller), I need to know the methods used to Test CAN Failure and Build in CAN Test.Methods I tried. 1: Checking Error Flag like Bus-Off Error Flag bit and Passive Error Bit, but due to Arbitration Failure Transmit Error Cou...

Good day! Somehow I can't seem to download files from the ST.com. The STM32 clock configr (STSW-STM32091) is unavailable to me. The Licence Agreement keeps coming back. Tried different PC's and browsers and chache cleaning. What am I doing wrong? Thanks!

STM32H7. The I2C_FLAG_AF flag on I2C4 is always wrongly set.

I have an custom STM32H743 TQFP100 board. I use I2C 4, PB8, PB9 at 100kHz.The code is generated with CubeIDE.The I2C_FLAG_AF flag on I2C4 is always wrongly set and the transmission after adress is aborted.The device sends an acknowledge.Is this an bu...

STM32F7 - using SPI (slave) with DMA to set a flag (I.E. no interrupts)

We are trying to use SPI1 as a slave to receive 11 bytes of data per transaction. I.E. SPI1_RX --> my_data_array[11] When an 11-byte transaction is received, we want the DMA to raise a flag that we will check (we can't afford to use interrupts, a...

How can I process the TIM12 update interrupt in TIM8_UP_TIM13_IRQHandler? - MCU: STM32F767 -

The TIM12 update interrupt is not occurred in TIM8_UP_TIM13_IRQHandler().However it is occurred in TIM8_TRG_COM_TIM14_IRQHandler()I configured TIM12 update interrupt as below;//TIM4: master -> TIM12: slavevoid  MX_Test_TIM4_TIM12(void) {  NVIC_Enable...

After flashing done and removing jtag, our application is not working

I am using STM32F439NIHx MCU. After flashing the code, I removed ST-Link V2 from my PCand restart the MCU but our application is not working. But if I connect ST-Link V2 to my pc then my application is working. What is this problem? Please suggest a...

I appear to be having some issues with my DFSDM Manchester clock recovery. How do I set up the CKOUT for a 10MHz Manchester input? Do I need any clock connections or does it synchronize itself?

I am using the H7 and have a 10MHz sigma-delta ADC sending the Manchester signal. I do not have a clock going to the ADC because it generates its own.The internal DFSDM clock is set correctly, I think. I have a system clock of 96MHz and CKOUTDIV is s...

Hi all, I am fresher to STM32L4 Cortex M4 controllers i wants to know about timer configuration and basic codes for timers am search web cant identify anything please help me how sample code for simple timer based operations. Thanks
