Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
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,I am testing UART via a loopback test. This shows that the expected data is being sent on TX and received on RX, but the receive function always times out.This post stated to clear the OVR and RXNE flags before calling the receive function, but...
Hello,I'd like to set up a log management system that would allow me to write to both the UART and a file (NOR flash).However, I'm encountering data architecture difficulties that I can't resolve.I'll typical want to write in my file only after buffe...
I'm working on an STM32 project where I'm jumping to code in external QSPI flash (address 0x90000000) after booting from internal flash. I've configured the QSPI memory-mapped mode correctly, and the jump to the external flash works. The interrupt ve...
Source code formatted - please see How to insert source code for future referenceFor example, I want to send NTS(net status): Dspic33 will send Hex string 4E 54 53 12 00 03 10 00 00 06 10 00 00 01 10 00 00 96 90 00 0D 0A (this is correct Hex data str...
I have an older STM32 Nucleo-F746ZG and I want to try and send some serial over the ST-Link. I am in Ubuntu with VS Code. I have successfully built the project and it appears to be running in debug mode. However when I try to connect and read the ser...
I am using STMicroelectronics.X-CUBE-AZRTOS-F4 and STM32CubeIDE to make an NetXDuo HTTP server serve a web page POST from the MCU. The sample: "rtos-docs/netx-duo/netx-duo-http/Chapter2" is a minimal implementation. It is not an ST project, and d...
I've tried to disable the XferHalfCpltCallback when using UART DMA transmit without any luck. I believe that you cannot change the callbacks, or disable them. Observations:When you call HAL_UART_Transmit_DMA(), the callbacks are set to predefined U...
HelloThis is my first post on the forum, always a happy reader in the past and happy STM32 user as well!Now I want to go a bit further then the standard IO and control. I want to implement LWIP + FreeRTOS with a STM32F7. And yes, the fresh generated ...
Hello Forum, I have a question regarding OTA and toggling between flash banks on a STM32L496. I have read many forum posts on here relating to this and I have reached a point where I need assistance as debugging iteratively is taking a lot of time....
Hi guys,unfortunately I am not able to find an example on how to use/configure the STM32F769I-DISCO with FatFS and USB-Mass Storage to be able to stick a USB-Stick into the board and read/write files. Can someone of you point me in the right directio...
