STM32 MCUs Products

I use the STM32F429 for my new products, and the Crystal for the RTC stops running when power goes away. I have a battery on it to run RTC, so I can I get the 32.768kHz crystal on OSC32 to run using the battery on Vbat??

For a three phase system, I want to stop the pwm of channel 1 using comparator 1, channel 2 using comparator 2, channel 3 using comparator 3. The current of each leg is being fed to concerned comparator. I can't find any method to do that.

Three comparators are fed with three currents of each leg. we want to stop the PWM of concerned leg whenever the current goes beyond the set value of DAC.

SDMMC2 on STM32F767 (pyboard D series) / f_mount returns FR_NOT_READY

Hi, I am trying to setup SDMMC2 interface with an SD card. I am using the pyboard d series therefore I am using the SWDIO and SWDCLK pins. The schematic of the board is here (https://micropython.org/resources/PYBD_SFxW_schematics.pdf).According to th...

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/* ...
