The PLLon and PLLRdy in the RC register of THE RCC based on STM32H750 are out of sync

Under normal circumstances, THE PLLRdy of RCC is controlled by hardware. When PLLON is enabled by software, PLLRdy is set by hardware. When the software does not enable PLLON, PLRdy is cleared by the hardware. I now have a device with a Farad capacit...

Hi all, i would like to make a my own bare metal code for stm32f401ccu. Here i have given my code. But it's not showing correct clock frequency. Anyone could you pls check it for anything missed or etc...

I am currently working on Nucleo-H7A3Zi-Q dev board. I am looking for a working example for FDCAN , I didn't find any FDCAN example from Cubemx For this specific board. Can Anyone guide me where I can find a closest example for this board? Thank you

Are there a STMF4 or STMF7 ADC overun detection code example?

Hi,I´m working with a STMF767zi and STMF429zi kits and I´d like detect ADC overrun. Sow I write the callbackup code:void HAL_ADC_ConvCpltCallback(ADC_HandleTypeDef* hadc) { flagOverRunCH1=0; if (hadc->Instance==hadc1.Instance){ // Overun detection/* ...

Synchronize Timers of 2 different Stm32f767zi nucleo Board

Hi everyone,I have synchronized the clock of 2 F7 nucleo boards with the same external oscillator. To do that I have activated MCO of a third nucleo board and then I have connected it to the Pin 29 of CN11 of 2 boards.2 Clocks of MCUs:I have used the...

STM32F429 Disco with HM-10

Hello! I just got the STM32F429 Disco board and I'm trying to connect it to the HM-10 bluetooth module. I'm completely out of my depth here, I was hoping someone could nudge me in the right direction.I've worked with the HC-05 and the HM-10 on the ar...

System bootloader jump from application STM32F030C8 seems ok , but state PA0 is changed WHY?

I try process USART 1 upgrade over bluetooth module connected here.App setup all and jump to system memory, but here PA0 change and reset my here connected bluetooth. PA0 isnt defined in AN2606 .

There is no DWT in the M0/M0+ kernel.

Hi. I am using stm32l01c6tx. I want to use a very simple microsecond function. Libraries I have added below. "DWT" "CTRL" etc. when I included the libraries. It says not defined. But they are all in the "core_cm4.h" library. This library is in Driver...
