'[AVR]: Looking for C utility code'

I am looking for some C utility code for Mega chip for serial I/O, servos, LCD displays, and ADC routines. I am not interested in AVRFreaks web site. Been there, done that. Had enough of the unorganized pile of led blinking routines and the attitudes.

Any help would be welcome.

Thanks.

I have AVR-GCC code for
+ Buffered serial output (mega128)
+ Driving 1 or 2 servos from a port pin (mega8)
+ Driving a whole stack of servos through a 4017 (mega128)
+ Single-conversion (i.e. not free-running ADC) (8 & 128 i think)
Sorry, no LCD stuff. Never managed to get one of those to work right.
I had one almost working with a PIC and then I fried something :(
BTW that's why you should just buy the right connector instead of
hacking one together out of bits of stuff you have lying around.

The code is kind of long to send to the list. If you're interested I
can put it up on my website.

Stanton,

I would be delighted if you could post it.

Don't forget to let me know the address of your web site too.

Thank you.

John

Hi John,

Ask on the AVR-Chat list on yahoo, or the relevant group for your compiler
(I know codevision have an email group :o)


Regards,

Kat.

Go to http://www.geocities.com/uav_fun/
and click "bits of code" on the menu on the left.

If there are any big chunks missing I probably forgot to convert
a "<" to &lt; and it thinks a bit of code is an HTML tag. I think
I caught all of those though; it looks OK.

The 4017 servo driver is kind of a mess (so few comments I'm not
sure what half of it does anymore; I know, I know!) so I didn't put
that one up. The regular servo driver is OK.

The AVR's timers make it easy to work with servos. You can probably
convert the code to other processors fairly easily; just look through
the datasheet to see which registers are different. The servo stuff
does need a 16-bit timer but can be made to work with an 8-bit one;
they just won't move quite as smoothly.
