Is there a way to use timers to trigger an interrupt at between 1.00BPM and 999.00BPM, with a 2 decimal resolution? I'm currently using an STM32F373 with 8Mhz clock for my timers, and set the Timer Prescaller to 8000-1, and set the ARR register to ...
Hi,I have for dream to be able to create a handheld game console like the PSP when I was younger. It's for this main reason I study electronics.I wonder if there is a kit that help me to understand and learn about the concept of it or something not t...
hiI use stm32f4 micro but an external interrupt pinwhen i increase frequency of the external signal connected to interrupt pin, the micro jump to hardfaultwhy? how I can detect the solution?
Hi, I have STM32F407 and trying to read/wirte from/to SD card and often the code get stuck in the this loop: static uint32_t SD_FindSCR(SD_HandleTypeDef *hsd, uint32_t *pSCR) { //... while(!__HAL_SD_GET_FLAG(hsd, SDIO_FLAG_RXOVERR | SDIO_FLAG_DC...
Hi, I am new to STM32. I am facing problem with UART interfacing. I have connected UART to GSM modem and I am using AT Commands to interface with modem. To test the commands and its response, I have connected the serial sniffer (UART to USB converter...
I have built a bootloader at the begin of CM7 flash memory. I want to update both CM7 and CM4 flash memory. How is it possible to stop CM4 execution before updating the flash memory and reset the CM4 core after update? All must be controlled only fr...
Hi amazing community.I am working with the following mcu STm32F103Since in the design of our board we didn't insert any real eeprom for saving some data we decided to use a emulation tecnique provided from ST Here below it is reported the header fi...

Hi, i try to get the COM35H3P70ULC Display to work with the STM32H747L-Disco Board using a custom Adapter PCB. The Display is connected using 2 Lane DSI and i tried to configure the DSI Host to communicate with it. I cant get it work or respond to an...
I need advice on setting up a 'primary timer/clock' to toggle a an output pin for 20ms, at a user set frequency of anywhere from 16Millihertz to 16.65Hz ( approx ) with 16 bit resolution. ( user sets value from 0 to 10000 )The primary timer/clock mus...
