I ask about G071 exampke code, but nobody replies, then i try use more specific question. My test display is round 240x240 SPI LCD. TE signal is fmark .(one pulse per frame)In partial or block window send method RAM in display is updated on random pl...
I place oscilloscope probe at reset pin of MCU it get low reset continuously time periodI observed RCC- CSR resistor which gives LSIRDY=1 AND IWDGRSTF=1 both are set How can I make them of and solve this reset problem?Below attached images of MCU ...
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...
