In an application, for reasons I don't want to discuss here I try to write the program being binary fully compatible for both 'F407 and 'F427. Sticking to the 'F407 as subset, the 'F427 seems to be pretty compatible, the only exception I am aware so ...
the RM0090 reference manual for 2014 ,in the description of the “Chip Select togglest�? different from RM00990 reference manual for 2018，which one is correct？The results of our tests are consistent with reference manual for 2014,Is it wrong in RM0099...
my English is poor，In the same program ,cpu 407 do not have this problem,only happened in 427，somtimes.It's like 2.3.4 Corruption of data read from the FMC. in <Errata sheet - STM32F42xx and STM32F43xx - STM32F427/437 and STM32F429/439 line limitati...
Hi all,I am working on a STM32F103VEtx MCU. In my firmware I have redirected the printf function to a UART for debugging purposes. When I start running the code, the printf function causes the hard fault handler to hit. Please see the call stack att...
I know that it's straightforward to just try, but currently I don't have the board at hand...This doubt has arisen while I was unit testing some corner cases of my timer functions on the development machine (with mocks and so on).For the common case,...
Hello everyone, I've made a code within my STM32f405 MCU that writes SD 4 bits wide bus onto an SD card. I'm making a program where "HAL_CAN_RxFifo0MsgPendingCallback" fills a "uint32_t dataCANID[14339]" array and increments a counter. This counter v...
DMA requests are still generated if the CCR is outside the auto-reload rangeThe DMA request is is generated when CNT reaches 0 rather than being disabled.Processor is a STM32H750is this a bug or a feature - it should be documented anyway
Problem 1) current draw does not change after entering sleep mode.Problem 2) not sure if program should resume where it stopped or from the beginning of main. Also any difference between waking by NRST or by A0 set to PWR_WKUP0?Mcu is 'H747 operati...

I want to know the current level of the channel-input filter's output, marked as TIxF on the diagrams and in narrative.I know I could read the respective pin, but that's not the same - it misses the filtering aspect, i.e. a single read might inadvert...
