QT interfacing with stm32 board through USB

[kk2507]

Hello, I am working with stm32 board
I have to establish communication between the stm32 board and qt gui through the usb(not rs232)
I have created gui in which 3 leds and 1 switch included.
So, when I select led1 ON these command I have to send to the stm32 board through USB.
Then LED will start blinking on stm32 board.
In stm32 board, we are using USB_FS.
So, in qt how I can establish these communication?Can you share me usb related projects or link using USB.
I am using only usb and not RS232 or serial port(UART).

Hi @kk2507 ,

Are you using your STM as USB CDC libusb device or USB virtual COM port to communicate with your application?

PS: I suggest you move this topic to the category Mobile and Embedded.

@ndias Yes, we are using usb as virtual com port

Hi @kk2507 ,

Although I have never worked with serial ports in QML, I think a good starting point would be: https://github.com/ayberkozgur/qml-serialport . It implements a QML wrappers from QSerialPort object.
