Hello.

I got one project board where I connected Vinculum USB chip on my pic 18F452. From this project board I want to send data to PC.

Till now I didn't work with Vinculum so any help is welcome.

Use Google to search for CCS code. Use this search string:

I'm using the VNC1L -- good luck finding code from anyone else that works.

Are you planning to send data to the PC just using the VNC1L like an FT232? If so, it's pretty straightforward. I can give you some help if you need it. I will say, though, if that's ALL you are doing, go with the FT232RL. The VNC1L is an awesome little chip *IF* you need USB host capabilities. For just a simple interface to send data to a host PC, it's some very expensive, complex overkill.

I obtained the CCS USB host dev kit documentation and example files, which helped a lot. I'm using some very heavily customized versions of the files to meet my specific requirements.

The first thing you need to do is establish communication with the VNC1L. If you are developing on your own hardware, make sure the various pins are driven as needed - VPROG high, etc. Once you have the PIC and the VNC1L talking, you are ready to do some real work. Let me know what you need.
