unexpected reset after changing the GPIO mode on Fly.

Dear experts, my STM32F042G6 is unexpectedly reset after I switched on fly CAN_TX GPIO to output GPIO pin.  for this I did this steps.1).HAL_CAN_STOP() and then  2). GPIOA->MODER &= ~((U32) "pinX");   GPIOA->MODER|= ~(U32) "pinX");I have also made th...

Cannot use SPI TSIZE in Simplex receive only mode on STM32H7 ?

A question about this sentence of STM32H7 reference manual:Receive-only mode: COMM[1:0]=10In master mode, the MOSI output is disabled and may be used as GPIO. The clocksignal is generated continuously as long as the SPI is enabled and the CSTART bit ...

Incorrect Datasheet RM0091 / STM32F0x{1,2,8}

On page 252, "Vdda = .3 V" is written twice. With this the calculated value is incorrect. The correct value is Vdda = 3.3 Vplease fix your documentation

Differences between PWM channels 2, 3, 4 in TIM8?

I think I am missing something obvious about a difference between channels 2&3 vs channel 4 in the TIM8 after staring at this for some hours now...I am using the STM32H750 discovery board, and created a project in CubeMX which configures PI2, PB14 an...

Software download issue

Software download issueHi, I have met the same issue like this. Should I also wait an hour until this package been prepared?

DMA sets NDTR to 0xffff when enabled even when peripheral (SPI1 rx) is not enabled or has DMARX set. All memory is in D1 (AXI) and peripheral is working using interrupts.

Is it possible to use STMG070 USART break detection circuit in non-LIN (normal?) mode?

Hello,I would like to find out if it is possible to use STMG070 USART break detection circuit in non-LIN mode.Specifically, I have an application where I use a UART configured for high-speed data transfer (over a megabit) in DMA receive mode. Rather...

Can the SPI run at another voltage apart from VDD?

The data sheet isn't specific, apart from one diagram Figure 13 that shows IO's box with an arrow from VDD that then connects to a level shifter to the core domain.Please advise. A real handy feature would be to alternative voltage IO for the SPI's...

When setting up pins to communicate using SPI on a sensortile I changed the Pins so one is the C and one the B GPIO, how would I set this up, I haeve only seen one somewhat related thread that wasn't comparable, thanks!

Why my timer encoder mode oscillates in the same values?

Hi, i'm using my STM32F7 nucleo 144 and i'm learning about timer encoder mode and i follow the example in the datasheet but when i check the CNT register it oscillates in the same values and if i use the A0-A1 pins the encoder works bad, can somebody...
