Hi, I want to create a timer with retriggerable pulse of specified length. Now I know timer can do it, but there is an issue with one pulse retriggerable mode that needs to be from outside trigger otherwise it dont work. My application is specific an...

I am using STM32L412KBU and read in different ADC channels.Now I see that the first read returns 23451, the second read immediately after returns 20338.I use x16 OVS, hence the big numbers.After the second read, values seem to become stable.external ...
Hi, I am planning to use stm32g030f6 and also use RTC peripheral with super cap to keep date. However, this IC does not have VBAT pin. Reading datasheet said, that RTC domain can also be supplied from VDD/VDDA pin, but this means that when a voltage ...
Hi,I am trying to make the ADC + DMA work a STM32G431CBT6 using STM32CubeIDE and the HAL library. I am used to making it work on other families like the STM32f103 etc.. However, here, when I program the processor using the debug mode and watch the co...
Hi all, What is the correct flow to use HAL_UART_Receive_IT() to receive uart data?The first package is lost first its first char,Here is the flow used now, From the gif, you can see "H" is missing for 1st package, and all normal for others.The probl...
Hello, reaching out to see if anyone can provide some thoughts on a project I'm working on. The project works but though I'm a longtime Arduino developer this is my first STM32 project - so not 100% sure of some of the parameters I've chosen are the...
Hi, I added TIM7 to application and configured it the same way TIM6 was. I need to use two timers for my app, code contains all the same setups for TIM6 and TIM7, except for the timer expiration counters, and I observe that the callback void HAL_TIM...
Hello, I have a problem currently, I am a beginner on stm32 and I would like to create a pulse counter but I cannot get the interrupts from my timer 3 to increment my variable. I don't understand then that the function is indeed carried out but it is...
I am currently using the STM32U575I-EV; I was able to flash the DCMI example project's code from STM32CubeU5 (Projects\STM32U575I-EV\Examples\DCMI\DCMI_ContinousCap_EmbeddedSynchMode) and I see the onboard camera's feed displaying on the LCD as expec...
