Tarsil said:Any ideas about the easiest way to conect a 4Dg display to a 12F683?
I'd realy like to use this chip so...no way I'm using a biger one.
Well...not quite. One digit is for diplaying the number of cells (is for NiCd&NiMh) eq.2,5....Another digit is for displaying C&D (charging and discharging). Digits 3&4 are for diplayng current ..eq. 05 (.05A), 20 (.2A) and so on.manish12 said:i.e LED = cell in your case.
right or wrong ?
if it is so ! than nice idea .
i dont konw , what i got ? , if i am right , than you have to think about charging current.
Maxim has a chip for everything but usualy on the expensive side. At that price I'd buy a 16F877A with a lot of goodies.Madhouse said:**broken link removed**
Take a look at this, it isn't a "cheap" solution but might give you an opportunity to save time/money/work elsewere. And in a 16PDP isn't too big either - especially as you can get some of your spare I/O pins "back".
Tarsil said:BTW...Does someone knows a uC (pref a PIC or 8051 clone) that has a 10 bit AD, a comparator,2k+ of flash and more than 8 pins?
And.....under 2$
Tarsil said:The next chip I could buy&use is a 16F877A. In the boxex It whould be OK to put a 12F683 and 2X595IC but a single 877A...whould be a problem due to the size&shape of the boxes (i'l have to cram inside a radiator, some power electronics etc.).
