I changed out of curiosity the max speed variable of my car ECU from 250Km/h to 60Km/h to see if the car reach that speed and hold there or I can go beyond and get a notification but it turns out that I cannot exceed that limit.Now, I'm unable to get...
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...
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...
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...
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, ...
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...
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...
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...
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...
