Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
At first, let me say that these are my first steps with the STM32H743 so it's really possible I'm doing something really wrong. I've been having issues with the USART which would show that the PC only receives some characters and others have invalid ...
Hi everyone!I am trying to interface my TETRA device with the microcontroller using the USB interface. The microcontroller will act as a usb host while the TETRA will act as a USB device. I am using STM32F469I-DISCO development board.How can I do suc...
I'm trying to get the USBPD middleware running with 2 ports: 1 source and 1 sink. I already followed the tutorial to get 1 port working as a sink. When I add the second port as a source, the chip immediately hits a hardfault after starting. I traced ...

This error callback function is not getting called when we connect to PC. But we are getting during modem (UART based)communication only. Whats purpose of this callback ? Is there any configuration need to add ?
Hi all, Just find a problem whenI trying to use STM32F205 w/ FreeRTOS CMSIS_V2. When I call f_mount in FATFS libraries, complier return "Middlewares/Third_Party/FatFs/src/option/syscall.c:65: undefined reference to `osSemaphoreCreate'". Once I go de...
I'm using STM32F439ZI development board. Now i want implement the my own Custom USB class. I'm new to this topic. Can any suggest the how to implement this one.Thank you.
In the code I wrote, it is very straightforward being initialising USART2, receiving a character from a serial monitor and turning on/off an LED based on the character received. The LED does not turn on, in this case when I type the letter 'y' on put...
