I have developed code (on the NUCLEO-L433RC-P) that uses shutdown and wake.The code works when I debug or run, but it stops working after a cold restart (power removed then reconnected).After a cold restart, the software runs correctly until the firs...
Hi allI am facing some issue related to measurement of VREFINT and VBAT which is IN17 and IN18 respectively,My ADC1 configuration is 12 bit resolution, 3cycles sample, one shot and software conversion.I ran few tests as follows1.vref which is 2.95 (V...
Hello all,I'm evaluating the STM32H743VIT6 on a third-party development board. I tested it with the system clock configured at 480 MHz (double checked everything, and all looks absolutely fine in terms of configuration). I did enable the "overdrive" ...
Hi all! I'm using the Nucleo-H755ZI-Q board and trying to write a simple program where the LED should turn on (and stay on) only when I press the USER button (the blue one on the board). I’ve shared a screenshot of my code below. The code builds and ...
Dear all, I'm calibrating the STM32G0B0RE RTC clocked by an external 32.768 oscillator using the following guide:https://community.st.com/t5/stm32-mcus/how-to-calibrate-the-stm32-s-real-time-clock-rtc/ta-p/744958Below is my debug code:int main(void) ...
In developing a bootloader and application for an STM32H5 project using STM32CubeIDE v1.19.0, and STM32H5xx HAL Driver v1.5.0.RC1; when I place the ISR at 0x08008200, I can start the debug process but the application appears to be stuck in void SVC_H...
Trying to get a basic sample DAC1 with DMA, triggered by TIM2 working. This should be trivial, works fine on SMT32F3. I'm using a Nucleo-32 SMT32G431.Using Cube IDE. The only non IDE-generated code in main is: /* USER CODE BEGIN 2 */ static uint...
Greetings. I am a beginner and an electronic student and I am currently getting my hands on STM32H523. I have created a mcu board in Altium Designer just to control LEDs by GPIO, hopefully to understand more about STM32. I have the PCB fabricated, an...
Hello,I have two questions regarding the STM32U0 series and the RM0503 reference manual:1/ HSISYS Divider ConfigurationIn RM0503, for the STM32U0 series, it is stated that HSISYS is a clock derived from HSI16 after division by a value from 1 to 128.T...
Hi all,I'm trying to get one pulse mode working on the TIM1 of the STM32H755. The goal is taking a pulse from one pin as a trigger, starting the pulse, counting 32 clock cycles on another pin, and then resetting the output. This controllers tech tuto...
