I'm using a STM32H747 DISCO boad and I just want to use the M4 CPU. When start, the M7 configs the Clock and does nothing since then. There is only a simple case running on the M4 CPU. The case takes 200ms on M4 while it took only 20ms on a Risc-v@30...
I am working on STM32u585. The STM receives data on SPI bus, cipher data and store cipher data on microSD.Then the microSD is read on PC and data has to be deciphered for human reading.What is the best mean to perform this ciphering process ? Can the...
I am trying to send commands to a Netion display which needs ASCII and then termination of 3 hex 0xFFs.I tried this: HAL_GPIO_WritePin(GPIOA, GPIO_PIN_4, GPIO_PIN_SET); char Cdata[11] = "bt6.val=[1]"; HAL_UART_Transmit(&huart1, Cdata...
I set up the VREFBUF (using CubeMx) to use the internal voltage reference, with a SCALE of 2.048V. When i probe the Vref pin i see a voltage of around 2.2-2.3V, it changes slightly after ever power reset. It is a custom board with a G061c8 micro. The...
Hello Community,I am working with "STM32F746G-DISCO" Board, "STM32CubeMX", "STM32CubeIDE", and "TouchGFX Designer" .I would like to program GRAPHICS Data in to "QUADSPI Flash".When i compile firmware in "DEBUG" mode, ".bin" file size = 2.3GB".elf " f...
I have my STM32F407VE successfully configured as a slave device. Goal is to emulate a PlayStation 2 controller.Where I am at right now is that I am trying to send a specific order of bytes so I can be sure that before I read and act on the command by...
Hi,I attempt to locate information about the firmware in flash. To do so, the data are stored in a dedicated section (called CONTROL_UNIT_SECTION):/** @brief Definition of the firmware info. */ typedef struct firmware_info_t { uint8_t id; ...
Hello,I face serveral data coherency issues on my dma buffer which is used to place the values of serveral ADC channels into it. This is executed on M7 contextJust as a reference, I have a dummy project without any MPU configuration and data cache is...
In STM32Cube_FW_WB_V1.12.1 the function HAL_SPI_Transmit() increase buffer point per sizeof(uint16_t) when sending data in 8 bits mode; this lead to 1 byte every 2 bytes not being send out. See the below snippet from HAL_SPI_Transmit() /* Transmit da...
Nucleo STM32H723ZGCubeMX 6.3.0Cube IDE 1.7.0Package 1.9.0Using CubeMX the UART2 is set up for DMA on transmit and receive. The code is working for transmit and I see data on the scope that matches what is being setup in the buffer. The transmit pin...
