In March is designed a USB LED Matrix board which I afterwards got manufactured at BatchPCB.
After about a month I recieved the board, but unfortunately it had some manufacturing defects. I contacted BatchPCB and got a full refund.
You can read more about the defects in one of my other posts. But now I’ve fixed the defects using a razor blade and some wire.
After a couple of hours programming I’m able to control the display using a nice GUI on the computer (made in Visual Basic 6). The programming is done in PicBasic Pro, and the flashing of the PIC18F2550 is easily done via USB, as I’ve installed Microchip’s PICDEM FS USB Bootloader on the chip.
