How to get going: run the USBDebugging FXE on a GP32 that has its USB cable plugged into your PC correctly - then run the USBDeMon app on the PC, and try pressing [A] on the GP32 - text should appear on the PC app showing a successful connection A couple of random notes about using GP32USB and the USB debugging console.. * because two programs cannot control the same USB channel at any given time, the debugging console ideally should be started once your program is running on the GP32 - otherwise it may interfere with any PC Link operations, etc. Ideally I should add a Connect/Disconnect button to assist with this :) * I recently made it so that the debugging GP32 code would not stall the app if called when the PC debugging monitor was not present - it times out after a number of retries. * Although the monitor is written in C#, 90% of what it actually does is entirely compatible with standard Win32, etc - I prefer doing UI's in C#, however :)
