About driving that LCD

[Eeyore]

Thanks to all who replied to my post about driving a simple LCD.

Thanks especially to Dave Platt who suggested the NXP 89LPC94xx devices. The
'9408 could have purpose designed for the task with an onboard LCD controller
plus it also has a 10 bit ADC and 512 byte EEPROM both of which I was looking
for too. In 1k+ it's a resonable $2.93 too.

Incidentally, it's only in LQFP packaging. How do prgramming adaptors work for
those ? I'm curious how a socket would grip the leads. I've intentionallly only
previously used PLCC parts of this type before.

You can certainly buy a clamshell test socket for LQFP (eg. Yamaichi),
but I'd use ICP/ISP instead.

snap.

the LPC family are great.

I recently did a design for some isolated I/O, and an LPC with two
opto's was cheaper than a couple of shift registers and 4 optos. by
quite a bit. Plus of course internally they are "proper" micros - I've
worked on projects using PICs, but ugh (fortunately others did the
programming). And I had the misfortune of using an AVR chip that didnt
have a multiply once. double ugh!

I was wondering about that. I didn't see that much about programming so far. There
must be some boot code of some description to allow that.

I nearly forgot to say it's got an 8051 core too. Just the ticket since I've plenty
of experience with that.

I don't know if NXP has gotten around to adding it, but ICD can be a
really, really nice feature.
