STM32 MCUs Products

Resolved! I need to make a decision between the SPC5X (or RPC5X) and the STM32 for a long-term high reliability project where I need to develop a working platform quickly.

Why does my call to FLASH_Erase_Sector fail all of a sudden?

I am working with the STM32F446 microcontroller and for over a year I've successfully been able to erase sectors from within my code using FLASH_Erase_Sector. Now all of a sudden my code gets stuck whenever I call it! I have looked at the Option Byte...

Is there an example to use external RAM for the STM32F429I-DISCO?

The evaluation board STM32F429I-DISCO has a Synchronous Dynamic RAM: ISSI IS42S16400J I must use this external RAM instead of the internal RAM so I had a look to the example from "FMC/FMC_SDRAM_DataMemory"The example looks quiete easy. Nevertheless I...

Resolved! STM32L072 Discovery Board cannot receive the UART data

Hi,I'm using STM32L072 Discovery Board and generated UART code using CubeMx, I'm able to transmit the data via UART but not able to receive the data. Please help me in this regard.int main(void) { /* USER CODE BEGIN 1 */ /* USER CODE END 1 */ ...

Backup data from the RTC when the main power is cut off

Hello everyone, I'm using RTC on board NUCLEO-L053R8, so I have some problems. How do I connect a battery in this board? I know that if I want save my battery lifetime I have to put my microcontroler in a mode as StopMode, but how can I do that when ...

STM32H743 HRtimer PWM

hi i'm using HRTIM for PWM output.i could complete pwm output. but i want to stop it at pulse count that I want.is there any good way to stop output at i set pulse counts??

H750VBT6 BKPSRAM can't keep DATA

Structure confusion DMA_HandleTypeDef vs __DMA_HandleTypeDef

This code is from STM32H7xx_hal_dma.hwhat is __DMA_HandleTypeDef describing ?is it weak ? for what purpose ?typedef struct __DMA_HandleTypeDef { void *Instance; /*!< Register base address ...

DMA Overhead (ADC to RAM)

STM32F446 in my case...When the ADC finishes a conversion and the DMA controller deposits the converter data into memory, what is the overhead ? i.e. How long does it take ? Is this shown in the documentation anywhere ?I would assume that as soon as ...

Precise clock for CAN in stm32l432kc, what's the best approach?

Hi,We are developing a board with the stm32l432kc comunicating thru CAN bus @500kbit/s, and after reading about the internal clock precision (1% at best for HSI16 in the 0-85C temperature range) we are concerned that it could lead to CAN communicatio...
