| HidLibrary.dll problem for C# and PIC18F4550 usb interface |

Hi........
I am facing some problems to read data from PIC18F4550 through USB. I am using C# express edition and HidLibrary.dll. As for firmware I am using CCS compiler.
Anyone please help me to read USB packet using C#?
Also let me have a good documentation about this.
Here is my sample code.... (not working)
| Code: |
HidDevice myDevice;
HidDeviceData myData;
public bool initialize();
public String read_data()
{
myData = myDevice.Read();
return myData.Data[0].ToString();
}
|
The program stopped at myDevice.Read(); and can not read.
I am eagerly expecting your help.

Download the CCS USB software package here:
http://www.ccsinfo.com/compilerupdates.php
There's a button for it. You need to have a current maintenance
contract with CCS to be able to download it.
They have a Windows application that talks to their Ex_usb_hid.c
firmware for the 18F4550.
Here's the directory in the USB package:
- HIDDemo Source
It's written in Delphi, but you can study it and see how CCS talks
to their HID example firmware. |
