We are using STM32F722VET6 MCU in one of our project.Memory defined are in linker as below:RAM : 256KBROM : 512KBStack : 4KBWe have configured below peripherals and developed an application code using user defined functions. Which is working as exp...
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...
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...
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...
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...
Is there a document outlining how to power and test the crystal oscillator from ST? STM32F405
Hi, Im senior engineer using stm32, maybe, not newbee.I know that Higher interrupt priority can occur when mcu still process lower interrupt.Higher interrupt , i mean, lower priority value in nvic register.but just now, I found gpio interrupt can dis...
I do not understand the difference between the different sampling rates (cycles3 - cycle480). I know it is related to the time given for the ADC capacitor. I also realise that more time should mean more stable reading. I ran some quick tests and I f...
I have a Value Line Discovery board - STM32F100RB and three of the outputs are connected to a 3v3 converter to get a 5v output. I have tried another controller board with 3v3 outputs to drive the convertor board and I get a clean signal. (Either 0 or...
