Hi every one!
How can I create a program that is interface by which PC and 18F4550 could communicate via USB (HID) communication. A simple program with three buttons(switch on/off leds) and one progress bar(for ADC signal). I mean, what is the program language that have direct access to USB port (may be C++,C#,Pascal or another program)? Just put me at the right direction, not to teach me on that language.something similar to this: Untitled.jpg
 

I assume you have looked at

if you download the MCHPFUSB framwork

there is plenty of sample code including a HID device custom demo
C:\Microchip Solutions v2012-04-03\USB\Device - HID - Custom Demos

this includes example PIC firmware USB device code and Visual C++ USB host code, e.g. using an Explorer 16 switching the LEDs ON/OFF and read a switch state. You can adapt this to suit your requirements.
it is fairly easy to implement VB.NET and C# code as well

Hi LillyMag,

What is "card based on µcontroller" ?

Try to describe your problem with more details, maybe someone can help you?



Best regards,
