COMP and OPAMP clock enable missing from RCC chapter in 'F3 RMs

Given similar memory mapping, COMP and OPAMP (where applicable) is bound to SYSCFG in the various 'F3 models. However, there's no information of the clock enable for these modules in the related RMs. It's presumably enabled by RCC_APB2ENR.SYSCFGEN, b...

Hi,Can i use usart instead of uart???RegardsAdrush

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...
