STM32H7's I2C4+BDMA method cannot read sensor data
Reading sensor data using the STM32H7's I2c4+BDMA method was unsuccessful. It is okay to simply use I2C4 or other i2c+DMA methods. The read function when using BDMA is HAL_I2C_Mem_Read_DMA, and when BDMA is not used, it is HAL_I2C_Mem_Read.
Can I create filesystem on flash memory(external),?
Hello I am using STM32F779BI controller for use of externl flash memoryI want to communication(read,write) with flash memoryso I want to ask Is it possible to create filesystem on flash memory like we create on sd card ?so i could easily communi...
STM32H747XI Eval board: trying to blink LEDs by different cores, with Keil + CubeMX: should I do MX_GPIO_Init() by both cores or just one?
For now, both cores start simultaneously, then CM4 stops, CM7 wakes it up. Both main() functions have similar code but for different LEDs:CM4: MX_GPIO_Init(); while (1) { HAL_GPIO_TogglePin(myPK3_GPIO_Port,myPK3_Pin); //Toggle LED HAL_D...
STM32VL-DISCOVERY
The STM32VL-DISCOVERY is seen by the computer as a disc and not as a serial port.I use win7. How to solve the problem?

HI I am using the STM32L475 IoT discovery kit, I want put my board into deep sleep and wake up every one hour based on event, I was considering setting up alarm clock. I am using x-cube-cld-gen library'r MQTT example. For now i have scene other examp...
iolink support for STM32L452
Dear All,We have our custom board in which we used STM32L452 chip. Now we want to access this board as iolink device.we have one reference code of "STM32L073RZ-Nucleo", so can anyone help us to port example code for our board means STM32L452 chip?Tha...
How much of a frequency drift of the driving clock from the grandmaster source clock will cause the "Incorrect flexible PPS output interval under specific conditions " errata to occur?
Our desire is to use the flexible PPS with fine correction for synchronization purposes. We are wondering if it might be possible to avoid the incorrect flexible PPS output interval with a quality grandmaster. Is it possible to get a clarification of...
