I would like to use the integrated Bootloader of the STM32H743 for updating the firmware over I2C. I don't have access to BOOT or RESET pins at the I2C master side, so my desired procedure would be:Send a command over I2C to my firmware. Once my firm...
Same question for pin PF14: can it be used as a single-ended ADC channel using ADC2_INP6 ?The Cube does not indicate if these pins can be used as single-ended ADC channels.Thank you.
Hello,I need to fill the stack with watermarks, but I do not have access to the assembly startup script. Usually I would do it right at the start of the reset handler, is there another way of doing this?
Hello!I'm working with UART+DMA+IdleDetection. I receiving long frames of data(250-300 bytes) 250 times per second at 921600bps without HT & TC interrupt from several sensors and one Arduino, then I send them by USB . Sometimes, I receive overwritte...
I'm using the ADC to measure power grid voltage and current at 10 kHz. For most of the time the results are coherent. however, sometimes I detected some strange values colected by the ADC, differing from the measures made with an osciloscope in the a...
Hi allI have a question regarding the clock output from STM32F446VCT6 MCU.Can anyone tell me whether the clock signal looks good for you?Because for me it looks awful. The signals are measured directly on MCU pin (trace is 2 cm and is not connected t...
Hello,I am struggling to use multiple USARTs. I tested that USART2 works fine but I cannot get USART1 and USART3 to work. If I can't use multiple USARTs at the same time, I would like to use only USART3. However, USART3 does not work. Do I need to ch...
Hi,I have enabled the interrupts for channel set (SETx1) and channel reset (RSTx1) by setting bits RSTx1IE and SET1xIE. I am trying to drive the outputs to active-inactive state via software by writing to SST and RST bits of the TIMERA.Inside the TIM...
Hi,I created my new project follow the SubGHz Phy Ping Pong project. I want to write ADC values to FLASH for 5ms then enter stop 2 mode for 1000ms. In PWR_EnterStopMode() function, the HAL_SuspendTick() funciton is called, but my project enter stop 2...
