Hi,I'm trying to control multiple PWM signals simultanously using DMA (used for controlling LED drivers). However I'm having an issue I can't seem to trace, one of the lines puts out an additional PWM signal cycle that shouldn't be there, this is wei...
I'm trying to build a custom HID device with the STM32F401RE board.I've got a basic keyboard recognized by my PC as a HID Keyboard from STM32_USB_training_course example as I expected, and "normal" key strokes works fine (letters, Enter, page up\down...
Hi,I wrote an external loader and tested for writing , erasing sector, erasing chip, reading, using "\testbinary1M.bin". But it failed in verification. What could be the reason? EDIT: I'm checkin what's going on by a logıc analyzer. I'm not using qua...
Hello,I developed a custom-designed system with an STM32F767 microprocessor and controlled its parameters with a user interface through a Bluetooth module. When I power off then power on the system, I couldn't communicate with the circuit board. Is t...
Hi I am trying to read ID of an external FLASH.The code which reads it is shown below.uint16_t FLASH_ReadID(void) { uint16_t tempData = 0x0000; //Read ID GPIOB->BSRR |= GPIO_BSRR_BR2; //Reset FLASH CS while(!(SPI1->SR & SPI_SR_TXE)); SPI1->DR ...
i'm trying to communicate with a Wifi module (esp8266) using STM32F103, on keil IDE. As described in the schematic : i want making my stm32 send AT command to esp8266 through usart1 (Tx1), and getting the esp response (Rx1), then display the esp resp...
Rev. 5 of RM0455 says "Reset value: 0x0000 4000" for PWR_SRDCR.However, the description "Bits 15:14 VOS[1:0]: 00: scale 3 (default)" contradicts this. And on actual hardware reset value is indeed 0x00002000.
stm32f429 Internal peripherals mmc 4.2，but present emmc 5.1。Is it a fully compatible driver?Is there a ready-made example？
Hello to everyone,I just joined the Stm32 family and I chose the STM32F373C8T6 chip to use in my projects. The reason I chose this mcu was that I used two different SPI communication components in the project I wanted to do. But since I am very new, ...
Hi,i'm trying to connect two stm32 boards ( STM32f446re-nucleo and STM32f469-disco ),my question is,is it mandatory that the two boards must work at the same clock speed ( sysclk ) ?Thank you
