I've been using the Picaxe 20x2 for awhile and I am pretty happy with that chip. Recently I have discovered a need for a 2.048 ref voltage for the ADC function and the 20x2 does not have that capability.
So basically my question is, what chip should I use to get the internal 2.048 ref and still be compatible with the 20x2 software and pin out configuration? If there is no "perfect" upgrade chip what comes closest?
Thanks,
Frank
