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 All,I'm a long time user/developer of STM32 micros (on STM32IDE) but until now have managed to avoid anything ethernet. However, I couldn't avoid it forever and work have tasked me with a fairly urgent project.I plan to design a custom board arou...
Reviewing USART protocol used in the STM32 bootloader, I noticed the system bootloader accepts some commands on the UART bus. By chance, will anyone be able to provide an open-source tool that communicates with the processor to send these UART comman...
Hi,I want to use USB DEVICE and HOST mode in same code. Firstly, I added manuel libraries for host and device configuration. I can do Transiton of host to device or device to host with using init and deinit function of usb. After a while , this proce...
Hello, I have a design with an STM32F446RCT6 where I use the FatFS file system and the USB HS as USB Host in Mass Storage Host Class.The design is made with STM32CubeIDE 1.8.0 and the firmware package is V1.26.2 / 16-july-2021.The configuration param...
I am working on a USB device based on a STM32H743 MCU, using ThreadX/AZURE and USBX.According to RM0433 (the reference manual for STM32H742, STM32H743/753 and STM32H750), the USB peripheral supports:- bidirectional endpoint 0- 8 IN endpoints- 8 OUT e...
I am trying to implement a USB audio device using ThreadX/AZURE and USBX, mostly by following instructions from: https://docs.microsoft.com/en-us/azure/rtos/usbx/usbx-device-stack-supplemental-2#usb-device-audio-class It's been pretty frustrating, un...
I am running a tcp server in STM32H753 MCU using LwIP driver. LwIP raw APIs are used for setting up the server. The server is sending a packet of size 200 bytes every 200ms.Ther server is connected to a single client(application running on an linux P...
I came across a documentation stating that arm m4+ processors have CMSIS DSP api that is implemented with SIMD instructions. When we try to take the library file to use it there are 2 variants single precision and doubles precision FPU. I assumed tha...
Dear All,i'm try to working on this beautiful discovery kit. I was able to create a simple gui in touchGFX with some buttons and managing virtual functions to set a text variable to some letters string. I'm now trying to send these texts to my pc usi...
I'm in situation programming STM32L552 (FD-CAN) MCU from classic CAN (CAN 2.0B) transceiver host through CAN communication line. According to AN5405, this kind of bootloader doesn't be compatible with classic CAN. However, for avoiding my hardware c...
