Hello everyone, I’m currently experiencing difficulties with setting up CAN communication on my STM32F4 microcontroller. Despite having configured the CAN interface and connecting it to a CAN transceiver, I observe no activity on my designated can_tx...
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...
Recently, I encountered a tricky problem, I used STM32F405VGT6 this IC, but I found that it could not enter DFU mode normally, after repeated troubleshooting, I found that when the chip was USB probed, HSE was detected and did not vibrate, I also saw...
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) ...
Hi, I´m reading the following document : "an4879-introduction-to-usb-hardware-and-pcb-guidelines-using-stm32-mcus-stmicroelectronics" to implement USB in my application. In section 2.6.1 Simple Resistor Divider it says "This solution works well as lo...
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...
