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,we intend to use the STM32F479 in an industrial application where ambient temperatures might vary, and we would like to use the system memory dfu as a backup bootloader. In AN2606 I found the following note:„For STM32 devices embedding bootloader ...
I am using the ETH module in the STM32H743 microcontroller. Added support for LwIP and DHCP. Everything works, the device receives an IP address and responds to ping requests. But there is a problem - the interruption of the ETH-module does not work ...
in CubeMX i can choose USB Device in DFU mode or Virtual Com Port, but i want to use VCP and upgrade firmware using USB port. Is it possible?
Hello,Is it correct to call HAL_SRAM_Init()for each external FMC memory ( So that each one has its own mdma handle )?The story:We have 3 memories: external nor, eternal sram, and fpga.But we don't get the dma callback called after calling to HAL_SRAM...
For the HAL Library file "stm32f4xx_hal_i2c.c", version V1.4.0, I see the macro "#define I2C_TIMEOUT_BUSY_FLAG " was added. Why was this timeout of 10 seconds added? Doesn't 10 seconds sound too much for a blocking call on the I2C bus?
Hello everyone, actually I'm working on stm32 Nucleo- F767zi board and I want to send/receive data over ethernet by assigning static ip to the board with the help of LwIP and Free RTOS. So when I just simple assign static ip to the board and it gets ...
I got a project to use one native UCPD of STM32G0 and one discrete TCPC (via standardized TCPM/TCPC solution). do I have to use 'USB-PD Power Delivery Software Expansion' ?what's the difference between 'USB-PD Power Delivery Software Expansion' and '...
Hi all,I managed to build HID + CDC for STM32F072 and STM32L152 and I am experiencing data corruption if I try to run both interfaces at the same time, however it is not happening always. I am testing on windows and linux (ubuntu 16, 18 and raspbian ...
Hello,I'm trying to use STM32CubeH7 SPI_FullDuplex_ComDMA example code inside a CubeMX generated project.I have been using the original SPI_FullDuplex_ComDMA (as it is) successfully.Now I copied it to my CubeMX project.First I have read the following...
Hello, i'm a begginer in stm programming and i've encountered an issue. I'm using two stm32F103 mcu which are communicating via USART1. One F103 is connected to the PC via USART2, that same device is also connected to I2C LCD 16x2 Display , a matrix...
