Hey there, at the moment I am stuck with the following problem: I need to trigger a SPI DMA Transfer precisely at each Timer overflow. NVIC Timer interrupts are not an option, because the jitter is way too high when I have to jump into code each time...
I am trying to implement a driver for an EEPROM. I created as follows: typedef struct { uint16_t address; uint16_t size; uint8_t *data; } test_t; And create a structure array as: test_t test[] = {{0x0000, 50, NULL}, {0x00AB, 70, NULL}, {0x0A...
Hello all, I want to use a NucleoU575 board to test an accelerometer sensor.I have written the driver for this accelerometer and currently, without having it connected to the Nucleo, I am trying to check whether my SPI3 Clock is working.This is the c...
I have a board that has a connector. Another board is mounted on top of it. This additional board may require either GPIO, or UART, or SPI on the same signals. But I need to change peripherals and work with pins without recompiling the code, without ...
I tried to enable spi 1 and I get this, but everything seems to be configure?
I use STM32L476 MCU I configured SPI1 master full duplex with DMA for Rx .When I use the HAL function: HAL_SPI_Receive_DMA(&hspi1, &RawSig[0], SigBufLng));The IRQ is not calledvoid DMA1_Channel2_IRQHandler(void){ /* USER CODE BEGIN DMA1_Channel2_IRQ...

Created a project template via CubeMX: STM32G030 is SPI slave and uses circular DMA bufs for transfers.As SPI master I'm using an ESP32 running micropython. This, though, should be irrelevant, as I don't rely on its output but what the Logic Analyze...
Hello to everybody,I have program for stm32f103 mcu. Now I want to do my SPI transmit routine using interrupt.Before:HAL_StatusTypeDef status = HAL_SPI_Transmit(&afe_spi, (uint8_t*) pData, 4,100);Now I tried this (and many variants also):HAL_StatusTy...
I'm using STM32F103C8T6 controller and I want to connect MAX30003 breakout board. Which preferences it's better to use for the best performance (STMCubeMX)? Can I communicate it with an SPI slave using the UART1 synchronous mode (configured with Cube...
