Hello everybody!I can't use USART2 in STM32G030K8 to transfer data.The TC flag of the ISR register is not set after writing data to the TDR register for an infinite time, if I use it to control the transfer of a byte, the program hangs without transf...
We have connected 7 channels in ADC2 to a STM32F769II processor. The DMA to ADC is enabled and the rank for conversion too is configured. But on testing, the ADC values are being shown in buffer location very different from its rank.This happened in ...
Hello!i am working with the STM32H745 dual core nucleo board.i have noticed that the app that i built runs perfectly when i debug it using IAR, on the other hand, it does not when i just connect the nucleo board to power and try to communicate with i...
please let us know the availability of STM32L496RET6 controller
i use two uart.(usart1 & usart2).when i receive data(usart1), first, the program will into "void HAL_UART_RxCpltCallback(UART_HandleTypeDef *huart)".but when i i receive data(usart2), second, the program will not into"void HAL_UART_RxCpltCallback(UA...
I have a project which uses SPI DMA, and the SPI DMA appears to fail when I enable the instruction cache (ICache! not DCache), but otherwise appears to work perfectly fine. I do observe this for both a F722ZE and G491RE.I'm working on this since 3 we...
Hey,I have both a NUCLEO-L432KC and a NUCLEO-F446RE. I'm using them to interface with an ili9163c based display. When I hook up the display to the L432KC it works great and I get a single image that fills the whole display. However, I'm trying to tra...
We are seeing an issue with the STM32L4R5ZI that does not boot 100% of the time if nRST is asserted after powering up (i.e., pressing and releasing reset button). We have seen this issue with the Nucleo board and with two different boards we made our...
