Resolved! Nucleo STM32H5 debugging OpenOCD
Hi all,I recently got a Nucleo STM32H563ZI board to start doing development with the STM32H5x family of microcontrollers but I'm having issues trying to setup a debug session in VSCode. I've download the STM32 OpenOCD version and compiled it as it se...
Missing DMA interrupt after I2C transmit
Posted on November 15, 2012 at 02:02I am working on an i2c driver that utilizes DMA for the master transmits. Everything seems to be set fine because I get hundreds of successful transactions but every once in a while, I issue a transaction but nev...
Two ADC in dual REGULAR SIMULTENIOUS mode
I am trying to run both ADC in dual REGULAR SIMULTENIOUS mode (ADC1 as master and ADC2 as salve) ADC Converted Result shall be stored in an Array Buffer using DMA transfer (single channel only), ADC conversion trigger shall not be software based (we ...
Resolved! STM32H755
Hi all,I got my hands on a quadrature encoder for the first time, and I am trying to interface it with my STM32H755 Nucleo board through the timer in encoder mode. The issue is that the interrupt is getting triggered (in the "HAL_TIM_IC_CaptureCallba...
Resolved! Encoder pin assign in STM32F103C8T6
Hello. I have plans to implement a motor encoder interface circuit using this micro controller. According to its datasheet, the timer implementation considers TIM1 ~ TIM4. My question is: which pins can I assign to implement a motor encoder circuit f...
Cube IDE Version: 1.15.0 failed at SystemClock_Config()
Hi : I updated STM32CubeIDE a few hours ago. Version: 1.15.0Build: 20695_20240315_1429 (UTC) Now it will failed at the SystemClock_Config() and missing arm_sorting.h void SystemClock_Config(void){RCC_OscInitTypeDef RCC_OscInitStruct = {0};RCC_C...
Resolved! Importance of Rext Resistor in STM32 external Crystal Oscillator
Hello ST community,I'm currently working on a circuit utilizing an ATS240C-E Crystal with a 22pF capacitor for an STM32 microcontroller. I'm curious about the necessity and implications of including a Rext resistor in the output of the crystal oscill...
Resolved! STM32G4 comparator source sink current
HiIs there any info available regarding source sink current of analog comparators on the STM32G4 series.The datasheet doesn't contain any info on this although the drive current of Opamps is mentioned as 500uA.TIA
Resolved! Voltage reference buffer (VREFBUF) in U545 packages
In the Datasheet it says:"The VREF+ pin is double-bonded with VDDA on some packages. In these packages theinternal voltage reference buffer is not available."Does this implicitly mean all packages which do not explicitly have a VREF+ pin can not use ...
