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...
Hi everyone,I'm working with an STM32F401CCU6 and trying to transmit 2 bytes over I2C3 using DMA1 Stream 5 Channel 6, which is the correct mapping according to RM0368 Table 28:DMA1 Channel 6 Stream 5 -> I2C3_TXThe DMA configuration appears correct, a...
Hello Sir,I urgently want to have an idea whether due to the change of LCD from HT043C KunJjian to RK043FN48H-CT672B Rocktech in 32F746GDISCOVERY Board, is there any changes in the firmware due to this?I would like to request for early response from ...
Good day,I've been working for a little on this and can't wrap my head around what the issue is, so figured I'd post here. As a start I'm doing a graduation project from a computer science education and am working on a project that requires a high sp...
Hello everyone, I am using a custom board with STM32H750 and I am trying to develop a file system with FILEX. The file system' s media is a uSD card with 10 MB/s baudrate which is communicating with the micro thanks to the SDMMC peripheral. The SDMMC...
When using USB CDC to communicate via USART, and interacting with USART data, in code is it recommended to interact with it at the USB side, or to interact with it at the USART side?From what I can tell, both offer both polling and interrupt methods....
Hello,in our application, running on a H533RET6 and with no TZ enabled, we need to close debug ports in production.I preliminarly did some tests using CubeProgrammer: I generated password-based credentials (obk+bin files, which as far as I understand...
I'm trying to enable USART transmission (TX only for now) via DMA, but when I call HAL_UART_Transmit_DMA, the transfer doesn't seem to start at all and HAL_UART_TxCpltCallback is never called.I've configured everything through CubeMX: enabled USART w...
Hello everyone, I'm having some trouble implementing I3C communication and would like to ask for some help. I am using the NUCLEO-H503RB board as my main controller. For the target devices, I have the NUCLEO-IKS01A3 expansion board and the TSC1641 ...
I want to make a pedometer app that would count steps and display the number of steps on an LCD screen. I have tested my functions for the screen (ILI9341 SPI), and they work successfully. I tested the LCD code by initializing a timer that incremente...
I am migrating from STM32L431 to STM32L471. After migration, the function relating to internal flash writing does not work any more. The problem is when I programmed internal flash with HAL_FLASH_Program(FLASH_TYPEPROGRAM_DOUBLEWORD, address, data), ...
