IAR external SPI_FLASH(W25Q128) download algorithm
Please give an example of IAR external SPI_FLASH(W25Q128) download algorithm for STM32F429IG, thank you
Resolved! STM32U599 DAC doesn't work in DMA mode.
I tried everything to send a simple wave through the DAC pin using HAL and STM32CubeIDE to configure the project. What I've checked that works: - Clock source- Trigger source- Output pin configuration- Built-in triangle and noise wave generation. I t...
Resolved! power voltage detector external input error in code generation with stm32G0
Hi ! i have found that if you try to select power voltage detector in (external input analog voltage) on Cube Ide there is a missing line in the code generated that make the code don't workhere an example of code generated for the option with the int...
skills: How to read DBUMCU correct without debugging
I am useing ADC with STM32H743ZIT6 device.when i debugging,i find that the device can't read DBGMCU vale correct，although I read the 0x5C001000 address directly, i was so confused. Fortunately, I found the following skill.So Step 1 : Download you fir...
Resolved! STM32H723 using DMA method to implement timer input capture can only be executed once?
Purpose: We would like to implement timer input capture in DMA mode on STM32H723 platform without interruption.Current Problem: Use Cube MX to configure relevant parameters, only use CH2 of TIM4 as the direct mode for input capture, select Reset Mode...
(Yet another) ADC/DAC synchronization question, STM32H7
Hi,I am trying to do synchronous DAC and ADC sampling using timers on the STM32H747.A simplified diagram of my configuration is shown below.Basically I want to continuously set DAC values from a fixed buffer and read the their equivalent "real-world"...
HAL_RCCEx_GetPeriphCLKFreq() getting incorrect PLL1 values (H5)
Hello ST Community,After running some tests on a board with an STM32H562 microcontroller and using an oscilloscope, I detected what might be a bug in the HAL. I was using the HAL function HAL_RCCEx_GetPeriphCLKFreq() to retrieve the clock frequency o...
Low power modes for STM32G0 series
Hi everyone,I’m working on a project with the STM32G031 Microcontroller, part of the STM32G0 series, and I’m trying to utilize its low-power modes (e.g., Sleep, Stop, and Shutdown) to reduce overall current consumption. However, I’ve noticed that the...
