Resolved! STM32U5 - missing USART6 clock config in CubeMX (bug?)
Using CubeMX I try to configure USART6 clock for STM32U5A9ZJT6-Q.It seems that CubeMX allows to set clock source for USART1-3, but not USART6.Am I missing something or it is a CubeMX bug.
Resolved! HardFault Handler changing Clock Frequency
Good morning, I am trying to read from adc two signals by first saving the signal with a certain clock frequency and then changing it using another one, i.e. changing the AHB clock divider. Going to debug it crashes on hard fault handler, regardless ...
How to configure multi-channel ADC sampling at different trigger using STM32G4 MCU?
Hello,I have a question regarding the use of the ADC module in the STM32G474MET6 MCU. I'm currently working on a grid-connected converter application that involves monitoring various sensing values. I've employed 3 to 4 channels within one ADC module...
STM32F103C8 with Watchdog Timer
i try to crash my code to check the watchdog timer is reseting the code or not. for crashing my code i use timer interrupt. i.e TIM2_IRQHandler(){ ---------------; ---------------;}TIM_IRQHandler() instead of TIM2_IRQHandler . so, code will be ...
STM32F410 PLL Jitter on PWM
Hello,i want to use a really precise PWM signal but i get a lot of Jitter on it.I am using the F410 with a 16Mhz crystal. The PLL produces from there a Frequency of 100Mhz (I need this high frequency for my other tasks).The rest of my hardware needs ...

Resolved! Issue with STM32F107VCT6 Data Corruption when Resetting nRESET
Hello,I am using the STM32F107VCT6 microcontroller and, under normal circumstances, it works flawlessly. However, I have been encountering an issue where data in a specific memory area becomes corrupted when I toggle the nRESET pin at 2-3 second inte...
Resolved! Some I3C Speed Rates are not available?
Hi，I am working with STM32H5RBT6U：How do I calculate the frequency of the I3C Controller? Is there documentation to cover the content?I tried using CubeMX to set the frequency, but strangely, all the frequencies work fine except 3~5MHz. The exceptio...
Resolved! RTC Alarm EventCallback called only 1 time
Working with the RTC I'm having some issue with the callback only being called a single time. void HAL_RTC_AlarmAEventCallback(RTC_HandleTypeDef *hrtc) { RTC_AlarmTypeDef sAlarm; uint32_t hobb_time; __HAL_RTC_ALARM_CLEAR_FLAG(hrtc, RTC_FLAG_AL...
