I would like to control an RC model via USB from my computer. I don’t need a real radio control, so controlling the servos directly through cables is sufficitent (yes, there will be cables between the model and the controlling unit). I thought I would build some microcontroller-based device which would be connected to the computer via USB and the servos would be connected to this device.

I’m asking for some hint where I should start. I know how servos are controlled and how should I eventually program the microcontroller to control the servos, but the thing I really don’t know much about is the USB communication neither on the device side nor the computer side (which will be Linux).

I would like to do the progamming in C (maybe Assembler for the microcontroller).

Thanks for every hint.

    You might want to start with something like an Arduino, which is a microcontroller on a separate board that you can talk to over USB. There’s great development environments and community for Arduino projects.

    If you use an FTDI chip alone, you will still need something to understand the RS232 serial instructions from the computer and to control the servo lines. This is where the Arduino will be really helpful.
