Hello to all What is the easiest way to communicate STM32Fxxx USB and (Delphi) program in PC? Who's idea is it? Please guide me.
The simplest way from the application (Delphi) point of view is serial port emulation. You can also implement custom HID device, which is not much more complicated. On ST32 side, for both exist frameworks that are easy to implement.
