Thanks

I am thinking of doing something similar. I would use a PIC microcontroller that has native USB 1.1 support. The 16F745 seems to be a good candidate:

it’s in dutch i’m afraid.

Also to get away from the surface mount both of these 2 chips come as 24-pin dip modules that can be used on a breadboard or perf board.

These 2 new chips are natively capable of High speed USB as well if you need it, no external components necessary to add that functionality.

I just wrote an entry on http://www.blogcadre.com using the new 232 chip, but plan on using the fifo chip soon in a design.

(sorry for the double post)

I have the CP2101, using it under osx… i wonder which is better as I’m considering buying a few to convert them to regular usb2serial adaptors. Branded ones, like Keyspan’s, are really expensive. This would be a nice alternative if you don’t wanna deal with the ftdi chip, which I believe only comes in surface mount. Then it’s simply a matter of getting a Serial2Parallel uart such as the 6402. I know it’s old and not that easy to get, but it works good and it’s simple as hell. Check here for a few example circuits : http://beyondlogic.org/serial/serial.html

I’m using a similar circuit to drive a 2×40 VFD and a 4×4 matrix keypad. Using RS232 is perfect for me as the circuit is located about 100~150ft (worth of cat5e) away from the host machine.

Lots of hobbiests use them, especially when their microcontrollers don’t natively support USB (some of the newer PIC’s do).

jared, it seems as if the 3590 and the 3510 are interchangable models where the lcd is concerned. Here is a pinout to the 3510, as well as a datasheet:

http://sandiding.tripod.com/ni3510.html
Epson S1D15G14 LCD Chip…

You probably won’t find any code, especially to drive that color LCD, so good luck and have fun hacking away. If you can’t work your way through the pdf, check out

http://www.sparkfun.com/commerce/product_info.php?products_id=569

they have code and pictures, which kind of takes the fun out of it.

Any ideas?
