Arduino for STM32

Hello again! Perhaps someone found a tutorial or saw it somewhere, or even knows this thing: via UART c STM32f103 I want to send data. I am creating a data buffer. On the RPI4, I want to open the serial port and convert this data as if it were a USB-HID device to display on the screen. In my case, ...

Thanks for the tips, I'll definitely try it!

Perhaps later I will describe how it turned out to be done in the end, if, of course, it works out.

Thanks for you answer! You helped me! I realized that I can upload new code to STM32 via RPI4 and UART connection by changing the jumper. Can you tell me which development environment to choose? As far as I know RPi4 has ARM architecture and not all applications can work. For example, I did not find...

Good afternoon everyone. I'm new in STM. I have STM32f103c8t6 with arduino bootloader. I can upload code to STM32f103c8t6 via USB. Right now my code is to send a message to UART1(Serial1). I connected this STM32f103c8t6 to Raspberry Pi 4 (RP4). On RP4 I learned how to read UART using pyserial. I hav...
