Hi, i did some research and when i do send and receive seperately then everything went smoothly, im using HAL_UART_Receive with RxCpltCallback: if(huart->Instance == USART2 && newDataFromPC == 0) { /*Receive data*/ HAL_UART_Receive_IT(&huart...
Hi , i am using STM32H753 MCU, it has 2 banks of 8 sector each using HAL_FLASH_PROGRAM function , it is not working, can anyone help me with this issue.int data;StartSectorAddress = 0x080E0000eg:(HAL_FLASH_Program(FLASH_TYPEPROGRAM_FLASHWORD, StartSe...
i am using stm32h743zt6 controller, what is meant by data retention in flash memory?where this parameter?how we can calculate this?Thanks,
Good day everyone.I'm trying to get Wiznet made W5500 working with STM32F030 series, using SPI in DMA mode.Unfortunately, in nSS hardware output mode, SPI bus pulls up nSS line after every transmitted byte (see attached image), while W5500 manual sta...

Trying to generate a 512 Hz signal that is synchronous to the LSE.MCU is an STM32L476ZETx.Measuring the signal on RTC_OUT_CALIB with a Keysight tabletop multimeter. (And also with an oscilloscope.)Observation:Setting "RTC_CALIBOUTPUT_1HZ": measured f...
We're using a STM32L4a6 with an ABRACON 32.768KHz crystal (ABS06-127 which is on listed in AN2867 as a compatible crystal) however we seem to be observing error in to order of +200ppm (not the +/-20ppm given in the crystal specs). Using 1p2F caps an...
I am working on STM32L476ZGT6 EVAL-Board for transferring data on the SPI to one of the audio codec which is SPI slave. I am trying to read the data from codec at 20 MHz SCLK. I am seeing that the data is getting right shifed 1 bit for of every byte....
