Dear STM32 Community, We believe that the example projects provided for the STM32Cube embedded software are a valuable resource when developing projects. We would like to better understand how developers use these examples in their workflow and e...
Hello everyone,I'm working on a project that involves UART communication between an STM32f429 and an nRF5340DK, with the nRF5340 acting as the UART transmitter and the STM32 as the receiver. However, I've been facing issues where the data received on...
Posted on February 28, 2018 at 12:19Hi,I've been playing around with FatFs for about 1 mounth now. I succefully used SDMMC and SPI protocol to save and read data from an SD card.I order to improve the system (it's a improvement for the project) We d...
Dear all, I just came across something strange. I debugged into the function HAL_InitTick() to better understand how the OS tick (SysTick) is managed if FreeRTOS is used. I'm using TIM16 for the SysTick of the OS. At the beginning of HAL_InitTick() t...
I have an optimized SPI Slave DMA setup which is driven by the chip select interrupt. It looks something like: int main(void) { // Initialize SPI SLAVE, SPI_DATASIZE_8BIT, SPI_DIRECTION_2LINES HAL_SPI_TransmitReceive_DMA(hspi, (uint8_t *)&spi...
We are migrating a project from H750 to H733 and I have run into an issue with our custom bootloader.We have our own External Loader, Bootloader and Application. Works fine on 750, but I have had to remake the projects for a move to the H733 micro.W...
Hi, I am trying to make the MCU the host where a USB can be connected, and the MCU can read/write to the USB. I configured my IOC /CubeMX to use the USB with FATFS. The USB USE OS (RTOS) is automatically enabled.However, the issue is that once the US...
I have spent over a week trying to get USB to work with my board, and have had no luck. As soon as the device detects the USB, the usb goes straight into a HOST_USER_UNRECOVERED_ERROR. I have received almost no assistance from STM32 regarding this, e...
My goal is to display text on the TFT LCD using stm32F756. The display I have is just the screen, no controller or gram. So I have configured the LTDC and was able to display a sample image which I stored in the flash. Now, the internal SRAM is not s...
Hello,I'm beginner in STM32 and would need help with HAL callback function usage.When I've started to use STM32s after PICs, one of the reasons why I was happy that the timer module encoder receiver function works really well, robust. I did used othe...
I want to initialize the STM32H573 ETH module using the STM32CubeMX code generator (see ioc file attached). It should run in MII mode using an external transceiver.I kept the configuration unchanged, however it always jumps to ErrorHandler, because H...
