STM32F746 Disco, UART1 connected to integrated ST-Link, Windows 10, STM32CubeIDE 1.7.0, Putty on PCI'm writing my own implementation of UART on registers in C, have datasheet and reference manual right here. I have no problem sending one character or...
Hi,device : STM32G473VBT6What is the best way to process SPI data when we don't know how many bytes will come from the SPI master ?I use the SPI in full duplex slave.The problem with DMA is that the DMA buffer is circular, where my processing functio...
I am trying to configure the SAI block in slave mode to receive a set of data. The Frame Sync signal and the data clock shall be provided from an external device. In a case where the active frame length and the frame length are to be decided by the m...
I have updated the firmware on my STM32H745ZI-Q and when I run in debug mode the code runs until:while((__HAL_RCC_GET_FLAG(RCC_FLAG_D2CKRDY) != RESET) && (timeout-- > 0)); if ( timeout < 0 ) { Error_Handler(); }The code stops in the error handler.Is ...
Hi,I have some issues with executing directly from QSPI with a NUCLEO-F412ZG and a connected Winbond W25Q80DV QuadSPI Flash which we are looking into as a workaround for the component shortage (will be a L4 variant but using a F4 for testing).Reading...
The STM32F303xB datasheet states that HSE oscillator should be used when using USB. I suspect it is because of the degraded accuracy of the HSI oscillator at temperature. I've had issues with CAN not working well with HSI at elevated temperature. Doe...
MCU : STM32H745Boot : booting from user main memory(0x08000000 )of flash memory ( boot0 :low)compiler: IARI am coding to write in address 0x08060000 of flash memory in Cortex M7 . Cache is enabled, MPU is configured below After at first writing 4444...
I have a B-U585I-IOT02A Discovery board, which is connected it to an external ST LSM6DS3 accelerometer via the SPI1 pins on the arduino connector. The issue is that the SCK line is going low when not active even though I have it configured to be hig...
Has anyone workding SDRAM on H753zi2 Nucleo?To start I have a F767 with the IS42S16160J working. Writes and reads back fine. Proven by disconnecting a line and the test code finds it.Move to H743zi2. No joy, it just reads almost radom back.I changed ...
