Update on PIC-USB boards

[Tim Williams]

I understand all the features. It's sounds like a nice project. I just wanted to point out that a stand alone USB chip can do the same thing and has many ports also. I look forward to the board.

Tim,

It's been a while since I looked at FTDI chips, but I believe the one you mentioned is strictly a USB interface chip, and has to be connected to a micro. I suspect that this adds more complexity in communicating with the PC. Also, does it allow you to easily reprogram the micro via USB? With the 18F4550 and the code Microchip provides, everything is done for you. No chip-to-chip communication or bit-banging.

The FTDI handle ALL USB controls. Yes I program the 16f877 in the Arc-Geo logger with my boot loader installed. It's a new chip and is recommended for new projects. If you want to purchase a license you can even program an area on the chip that will say "Arc-Geo Logger" found when you plug it into the USB port.

You can do that with the 4550 without paying a royalty.
