I promised some pictures in the beginning of this thread so here they come.

This is the FTDI chip soldered in the first proto:


This is another proto I've been working on lately:


Slightly newer version of the same thing:

Very nice Henri! You've been busy

Well, one thing is for sure - it has not been progressing very fast. I found about these FTDI chips in sometime first half of 2002 and started planning this. Then it took about a year to really do something and then put together the first prototype which worked very nice. Now almost a year after that I finally started working on a more compact version of the hardware.

Hehe, I know the feeling. Been working from 5:45 am till 7 pm and that'll continue for some months... so lots off ppl begging to get these projects finished

Anyways, if you need some assembly code, let me know. It's written in MPLab, contains bugs, but might be helpfull.

Thanks for the offer. I think I can manage this myself but if something comes up I'll let you know.

I have modified the code from my previous AVR based proto to this one (I'm using C) and the thing is running with LCDInfo now. I also wrote a bootloader that allows loading new program through USB to speed up development and to make future upgrades possible without programmer hardware. While writing the bootloader I noticed that using C it's easy to write code that takes very much space. But after looking at the compiler generated ASM and keeping the processor limitations in mind I was able to get it much smaller without switching to ASM.

Wow....I'm really impressed. All my LCD work with LPT Port. But I want to control them via USB, too. Can you write or give me a site where a completly
newbie tutorial is ? That tells me exactly which Chips to use and so.
Please Help

The best I can think of a newbie tutorial is Zotty's project pages about very similar hardware: http://liquid-mp3.schijf.org/usb2lcdii.html

Hmmz, I never considered it to be some sort newbie tutorial... lol. In any case, the section needs some work, so if you have things you need to know which would be usefull for other people to know, let me know (got to read that text twice you know ). Might as well update it with some good info if that's missing!

Heh, maybe newbie tutorial isn't the best way to desribe it but still it's the best I'm aware of.

Today I have finished newbie guide on USB-LCD.
My goal was minimize number of parts. I using Motorola MC68HC908JB8 with integrated usb-lcd module.
