Autonomous USB MIDI interface

[milk]

I've also tried what happens if I disconnect the cable and try to read/program, I get all 0's.
If I try to program with the ic not in the socket but everything connected I still get all 0's


you think the pic is busted?

you are from France, right?

Yes.

Do you plug the USB when you program ?

Yes.

Yes I do.

I'm going to try this http://electronics-diy.com/electronic_schematic.php?id=752 programmer and see if the chip is busted.

Still no luck getting another pc with serial port.

Cheers, and thanks for all the help.

Hi. Im from Argentina too, and im also building megadrum. I use the JDM programmer for PIC programming, which is cheap and easy to build (really cheap and really easy- I made it using an old tv parts) . Although I must say I havent programmed mine yet, but ill do it tonight and post results.

Why use a PIC programmer ?

Its kinda easier, more straight -forward, and reduces the chance of making mistakes, i guess. Might work for some people. Plus, it is a nice and useful device to have.

saludos!
