I've done wonders with TQFP PIC16F887's (capable and cheap) and ULN2803A (also cheap)

Mostly AVR Studio, but learning BASCOM Basic.

They also work from a Joule Thief, if you add a diode and capacitor...

Great Info the more the better. It would nice if someone can move this to chit chat. Since its not really a technical thing.

Thanks.

If you are thinking commercial I would suggest that you consider supporting the lower end PICs, like 16F628A, 12F675, 16F887 etc. Hobbyists have these in stock, also the hobby oriented parts suppliers stock these (+ heaps of them on Ebay etc) so they are seen as "standards" in a way. If you use the newer/bigger PICs exclusively you will alienate many potential customers who would like to use the chips they know/have/can get/can program.

I like the tiny11's myself, unfortunately they've been discontinued, they didn't have a lot of features but they were only 50 cents. I miss them terribly, I still have a few from my last Digikey purchase, they make great LED blinkers. The Tiny25/45/85 (different memory sizes) are my next favorite, massive features in an 8pin package. The tiny15's are nice for switch mode or motor drive applications because it has a PLL module which allows a PWM out of up to 100khz at 8 bit. For a few extra pins the tiny26/46/86's are nice, for real projects the Mega series has everything including the kitchen sink built in.

I prefer AVRs over PICs, for many reasons, mainly it's because AVR's are newer than PIC's the feature set is much more standardized across the entire line of products so it's much easier to 'change gears' than it is with a PIC. Even the tiny11 has the same core features as the Mega series. The same can not be said for PIC's where moving from say the 12 series to the 18 series is basically re-learning the whole chip from scratch.

Sweet! thanks guys. i see these seem to be a fav.

ATTINY45
ATTINY46
PIC16F628A
PIC16F887

someone referred to a AT91SAM7.. Those are so expensive i can see why a jump to a LPC would be nice. Its about the same price and has more features.

check out the sale:

The tiny25/45/85 26/46/86 are all effectively the same part. The odd part numbers are 8pin the evens are 20pins The 2/4/8 is available programming memory, also from low to high it's 128/256/512 bytes of eeprom and SRAM each.

AtomSoft · 29th May 2009, 01:07 PM

heh thanks. Even tho they are basically the same, Physical size changes alot since there are more pins to work with. Different Project ranges.

I like them all. But I have to say the 18f1220 which is just less ram then it brother the 18f1320 I like the best It easy 18fxxx chip to start with and I don't need a lot of pins to control two motors and some Ir sensors. But the neatest thing I did with it was a combination lock with 3/4 keypad and a light dimmer.
