Once I get up to scratch with the pic stuff I would like to interface a .net app to the picf4550 through usb, I have read that the picf4550 is a usb client device.

I'm just getting started with PIC controllers and I don't think I would have been able to find a better "Getting-started" tutorial. This has really helped my frustration level go WAYYYY down. Thanks for the great tutorial, Andrey!

I have programmed PIC16s and am now learning the PIC18. I needed a quick start for testing my setup to see how things are working. The ability to toggle an LED allows me to gauge how the oscillator is working by the output switching and giving me a value my freq counter can read. Thanks for doing such a nice job!

I would like to note that the data space reservation at the beginning of your program test2.asm is wrong. The MPASM compiler says: "No memory has been reserved by this instruction". This will result in an infinite loop (instead of a finite delay) and the LED will not blink. The correct code would be: CBLOCK 0x00 Delay1:1 Delay2:1 ENDC ORG 0x00 .... Best regards: I. Cserny Hi!

And it still works ? IMHO after RESET, BSR = 0x00. And all special registers like PORTD, TRISD etc. are on page 15. Can you explain it for me ? I programmed only 16F processors and they are a little bit different... You did not set BSR to 0x0f ? And it still works ? IMHO after RESET, BSR = 0×00.
