Hello, I am using STM32G030F6Px, it has 32 KB flash memory and I need free space to save data in flash, also it needs to have bootloader. That's why I decided to use bare metal code instead of HAL library, of course I did this by examining HAL librar...
I am working with the STM32F446 microcontroller and compiling with Eclipse/GCC. Short version: I have two functions, main1(int argc, char* argv[]) and main2(int argc, char* argv[]) and I want to be able to goto back and forth between the two many tim...
Hello,I'm using stm32h757i-eval board & STM23cube ide for programming.I have successfully achieved the UDP communication.But there is one problem.I want a trigger or auto polling function for the UDP_RECV i.e, when ever there is a input data availab...
I have default setup under linux with CubeIDE 1.7.0 and for overriding, i had to modify as __weak void HAL_PCD_ConnectCallback(PCD_HandleTypeDef *hpcd);__weak void HAL_PCD_DisconnectCallback(PCD_HandleTypeDef *hpcd);oh header definitions. Otherwise i...
Hi,I generate a sine wave on the DAC. To trigger the DAC, I use the TIM 2 timer, which is clocked on the APB1 (32 MHz) bus, then I reduce its frequency through the dividers PSC = 15 and ARR = 1. In this way, I obtain the frequency from the timer equa...
Hi, is there a reason to implement the HAL function over simply running code inside the IRQ handler.In my current case I only am incrementing a counter and do not need to demux the line, so I presume not this time, but if I was doing something more i...
I am trying to read from an external SPI ADC at a 1MHz rate using a timer and 4 dma channels.I setup TIM 3 to run at 16 MHz and rollover at a count of 24.CC1 pulse is 1, cc2 pulse is 2 cc3 pulse is 22. CC1 drives DMA1 stream4 which is setup to trans...

Hello.I implement the SD Card access using the SDMMC1 on the NUCLEO-H743ZI board + SD Card sub board.Now the SDMMC1 Interrupt was not occurred after the DMA request setting and SDMMC interrupt enable(DCRC, TIMEOUT, RXOVERR, DATAEND) for reading the M...
