MCU : stm32h743ii. two usart problem
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...
SPI DMA fails (only) with ICache enabled, why?
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...
Resolved! Why would DMA behave differently on two NUCLEO devices (F446RE/L432KC) ?
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...
STM32L4R5 not always booting after nRST
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...
Resolved! STM32H743ZI Direct channels for ADC.
Hi,I am using STM32H743ZI micro controller of LQFP144 package. My doubt is that in the data sheet they are mentioning that it has 2 direct channels for ADC but they are not mentioning what are the channels or pins offering thisThey are only talking a...
Chain two timers
hi friends, I try chain of 2 timers on STM32L053. From 2 16 bit timers I would like to create one 32bit timer.My init is here.void CLOCK__TIM21_Init(uint16_t Prescaler) { //initialize tim21 as master //enable clock to tim21 LL_APB2_GRP1...
Resolved! Can't connect to target STM32f105RC.
Hello Community!I was using a system controlled with the STM32f105RC, I was able to program it with the ST-Link. In that system I got a problem so I had to change to another board with the same characteristics but, when I did so, I wasn't able to pro...
Is FT5426 similar to Ft5336
HI, I am using a custom board where i need to devlop a touch driver. I am using FT5426.I have the complete code of fT5336 as it was used in STM32f746-disco board.can i just by changing the register AND CONFIGURING the i2c pins accordingly.make the to...
