STM32U5 sometimes does not reconfigure IWDG.
At startup, I set the watchdog timer to 8 seconds.IWDG->KR = IWDG_KEY_ENABLE; IWDG->KR = IWDG_KEY_WRITE_ACCESS_ENABLE; IWDG->PR = IWDG_PRESCALER_64; // 8 s IWDG->KR = IWDG_KEY_WRITE_ACCESS_DISABLE;Further, in the interrupt, when the button is pressed...
Trigger out and ADC using timer TRGO
Hello ST Community,I have a question about the way to trigger out an ADC using internal timer TRGO, i would like to use an STM32L4 or STM32U5 for this function, so i'm using an External Time Reference (ETR) signal and i would like to know if there is...
Implementation of Dali DT8 Protocol
I would be very grateful if anyone has information about setting up the Dali DT8 4Channel protocol and can guide me.And does anyone know that DiiA standard certificate is given by ST company to buyers who want to use Dali protocol? In other words, is...
HRTIM center-aligned mode with 100% duty?
Is it possible to achieve 100% duty cycle on HRTIM using center-aligned mode?when HRTIM1->sTimerxRegs[5].CMP1xR = 2124 (PERIOD-1), the duty is almost 100% end when HRTIM1->sTimerxRegs[5].CMP1xR = 2125, the duty drops to zero. As per the code below, ...
STM32H7 : USART3 DMA doesn't work after jump from bootloader to application
Hi,I use an STM32H730 with default bootloader. After I programmed the chip, if I use the "jump to application" feature, USART3 RX DMA in my application does not work anymore. (this DMA works fine when starting the MCU directly in application mode wit...
Resolved! Hi! I am having isues regarding hal function for setting the pwm duty cycle. I am using stm32f401cd. __HAL_TIM_SET_COMPARE is not setting the value.
aI don't have a scope but i can measure from multimeter, if it is there. I am guessing there is a bug or I am doing something wrong. I think software focuses on Pulse value and does not recognize __HAL_TIM_SET_COMPARE command. I uploaded the code. An...
STM32H7 ADC clock and conversion rate
Hello,I'm using a STM32H427ZI rev Y. 20Mhz crystal and ADC to convert 4 channels in scan mode, using a timer to start the conversions (500kS/s) and the DMA to get the data.PLL2 is configured to 80MHz (the max undivided ADC clock is 100MHz). I would l...
Resolved! Stm32G030 Timer : problem by using TIM17 OC1 as internal trigger for TIM1
We use Stm32G030C8 for our project, which has only 16bit timers.But we need 32bit timer, therefore we are going to combine two timers.We could combine TIM1 with TIM3 successfully – TIM1 as slave and TIM3 as internal trigger (ITR2).Unfortunately we ne...
STM32L0 LPUART not wakeup on stop mode
Hello everyone,I'm working on a project with an STM32L072CBT6.In my project, i use a LPUART1 and USART1 to send and receive data. Connected to this i use a DMA to get data.My projet works fine so i try to implement stop mode to reduce consumption.In ...
