PIC18F4550 interface with PC through USB

pic usb interface

Hi all,

I am new in MCU PIC18F4550, I am trying to program the MCU to communicate with PC through USB.
I bought the ccs compiler PCWH and microchip's demo board.
The terrible thing is that their resources are belong to different coding,
I am frustrated in it. Is anyone tried to use the driver provided by microchip and program the MCU with ccs compiler?
Can anyone suggest me how to get start on it?
Thanks.....

Hmm ...

Try mikroC. It has excellent library for USBHid interface and more over it works ! I had tested it.

you can use C18 compiler from microchip with MPLAB IDE, also microchip offers a ready made USB firmwares for many platforms including PIC18F4550, check this link:
**broken link removed**

good luck

See the attached file.
This is complete project in ccs c.
Also C# interface.

I'm learning programming with CCS C and have wondered how i will ever use most of their rich source. It's great opportunity to get hands on USB interface. Hope to get help subsequently. I also programme in mikroC. I'm just comfortable with C syntax for PIC but want to take it to another level like good use of libraries and more.

Hi!

I've tried the project what hina33 suggested. I don't know why, but I can't install the PC driver for it.
