hello everyone, i finished my 2 axis and 7 button joystick, plugged it into my PC and checked the device manager and everything was working OK
then i unplugged the device and went on with my life....
later, idecided to check my device again and plugged it back into the PC, "unknown Device" showed up on the device manager, i uninstalled the controler for this "unknown Device" and unplugged and plugged back in and i still get unknown device from the device manager.
i was wondering if there is something that went wrong with my coding or with my circuit (maybe i burnt my PIC for some reason) i will attach my code and my schematic for reference.
maybe i did something wrong, please advice me. this would be greatly appreciated :D
Schemmatic;
ignore the LEDS on the diagram (i did not place those there) and C3 is 330nf instead of 470nf
on the outputs you see in the CODE i used an LED connected to a 4kohm resistor an then to GND
i also connected POTS of 2khoms to AN0 and AN1 (RA0 and RA1)
