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...
Hi,I am also trying to test a bare STM32 IC "STM32L4P5RET6", but have been unable to program it using Nucleo.I have tested the following connections and it seems to be working.https://os.mbed.com/media/uploads/mega64/2nucleos_2.jpgCan I replace NUCLE...
I am using the STMCubeIDE version 1.8.0I try to create a STM project for a STM32f407VEI get the error message as many users : the IDE does not find the 1.26.2 firwareI tried to follow the solution to install with the Import from local option, this do...
Dear Community,I'm recently having some trouble with STM32F7 DMA (STM32F767 Nucleo, STM32CubeIDE, some HAL stuff, but using more and more direct register writes & reads).I'm using timer input capture with circular DMA from timer peripheral to memory,...
Hi, I have a low power controller which i will use as RTC.type: STM32L031F6P7.I use a custom boardThese are the clock settings I also notice there is no oscillating signal at PC15 . When should the LSE oscillator start? after powerup or after System...
HiWe are using the STM32H7A3ZIT6 for one of our irrigation controllers that we are developing. To check the "power cuts" time, we always save the RTC value (uint_32 seconds value) before voltage goes down, using:HAL_PWR_EnableBkUpAccess();HAL_RTCEx_B...
