hi community,currently I am using the STM32H743zit6 board.My query related to the SPI slave mode.To test SPI master and slave mode I am configuring like this.SPI4 is used as Master it always receives data in full duplex mode and MISO is configured a...
Also how to internally connect the input trigger to two simultaneous one-pulse generators.
HiI'm trying to get SPI output working using DMA with the LL drivers. I'm using CubeMX to set up the DMA and SPI and it works perfectly when I use HAL_SPI_Transmit_DMA to initiate the output. However, this is a very slow routine and I want to be able...
I am trying to determine the cause of resets happening in my application. It does not seem like the RCC->CSR register is working properly.I tested this out by manually grounding the NRST pin and setting a break point in my code before main(). The CSR...
Hello,I'm working on target STM32H743ZI.I would like to copy a memory buffer to the SAI interface (master).For some reason, when calling the function HAL_SAI_Transmit_DMA in the main, no transfer occurs. Going through more details, it seems that the ...
Hello, Technical Details: CMSIS- RTX based RTOS.STM32H7xx based MCU.Problem Description:I am trying to find the duty cycle of a incoming PWM. And my problem occurs when there is an interrupt and now the interrupt handler executes properly but It does...
Hello,Some background:STM32CubeIDE 1.6.1MCU: STM32L4R9ZGJ6SDK: STM32Cube_FW_L4_V1.14.0 (Yes I know it's old ~ 2019) Project is too large to update at the moment.I am currently debugging external DAC audio issues. I reverted to using simple SAI blocki...
I tryed two methodes, one just jumping to that address 0x1fff0000 via function pointer and second writing some magic numbers at 0x2001fffc and placing some asm code in the startup *.s file to jump branch to the system bootloader. I had to change cont...
For F73X, there is following code that avoid resetting date/time:if(LL_RTC_BAK_GetRegister(RTC, LL_RTC_BKP_DR0) != 0x32F2){.. LL_RTC_BAK_SetRegister(RTC,LL_RTC_BKP_DR0,0x32F2);}Shouldn't H7 behave similar to F7, regarding RTC initialization?
