Resolved! Recognizing SPI data reception in STM32F429
I'd like to ask how the STM32F429 recognizes data reception in case of SPI while there is no any start bit? I know that there is RXNE bit in SPI_SR status register, but how SPI knows where is the first bit of the transmitted byte? Is it somehow sync...
How to do a SPI communication on STM32F7 without DMA
HI everyone, i'm trying to do an a SPI communication between the board STM32F746 and the MAX7219 to controller a matrix. i'm working in keil uvision 5 and programming without libraries, DMA, CMSIS or other. i programm through registers putting '1'. i...
Please correct my function ?
Dear Member,I'm confused between pointer and array,Please correct me :void sim7600_modem(char *SIM_TxBuffer){ printf("sim7600_modem ATI\r\n"); //Clear buffer HAL_UART_Transmit_IT(&huart1,(uint8_t*)&aTxBuffer4, sizeof(aTxBuffer4)); HAL_Delay(5...
Wrong data on I2C 2 ?
Dear Members,I got a wrong data on I2C 2 for LCD, the first time it was ok, after a while it becomes like in the photo, what do you think the cause of it ?I have put a pull up resistor for it 10K, and the speed is 100KHz,I2C1 for Accelerometer and te...
Subsecond resolution alarm on a RTC without subseconds (STM32L152 Cat.1)
HiTimekeeping in my application is pretty standard: 32 bit unsigned integers which store milliseconds since boot, overflowing every 49 days.To reduce power consumption, i need a way to wake up from stop mode at a set time in ms. But my device has nei...

Resolved! Strange problem when using Keil and debugging STM32H747 Discovery. Concerning RAM address
Hi, there, I am not sure this is the right place to ask if it's concerning IDE.Just got my new STM32H747 Discovery kit, running CubeMX examples,All running well, except for debugging:(I am using MDK Keil (V5.27 / V5.28) and on-board STLink V3)I found...
