I am using STM32H7 General Purpose Timers TIM2, TIM3, TIM4, TIM5 and their respective external trigger ETR using combined RESET and TRIGGER modes and I am configuring and starting Channel4 for each to generate One-Pulse output . All the configuration...

Hi, What are the revisions of the STM32F411CEU6 chip?The ERRATA doc from STM mentions only revision "A" . Are there other revisions?I received board with revision "1" .

I am coding STM32H743 MCU with CubeMX generated library.I have 1 SPI Master and 1 Slave. Both configured for a full SPI with both lines of Tx and Rx.Master is calling blocking HAL_SPI_Transmit() or HAL_SPI_Receive() but never simultaneous HAL_SPI_Tra...

I had a perfectly working setup:Target STM32F411 , a probe Segger J-Link mini, GDBServer configured with SWV trace running at max speed over SWO wire, STM32CubeIDE and all it's "underwear" was upgraded to the latest (current) .The only old version in...

Hello, I searched all the documentation for STM32F4xx MCUs to find the proper source of the clock for each of SPIx peripherals - no result. Please somebody point to a proper document/chapter/page ...All chapters on SPI in the reference manual talk ab...

I came back to provide the answer to my question for those who may have the same problem.The chip indeed allows One-pulse generation while triggering the slave with any of the possible slave triggers: ETR, internal triggers ITx, or input channels TI1...

Two years later I have the same function bug in STM32H7 Cube library. Still ignores the Output Channel passed parameter and enables Channel 1 and 2 instead.Are the bug reports ignored?

Anyways I received a confirmation from ST support that this version "1" is authentic revision of this chip, functionally the same as release "A" but produced in a different fab. Also they will update the errata doc to show this release.

Thank you Tesla, I don't need ST tech support now...Can you please share the secret? Where do you get this information? What is a way to identify the fab?

eBirdman · 2022-05-28

Thank you Jan. This is very likely that this revision number is from a new fab . But I will contact ST support to verify.
