Revision:
1:f30bdcd2b33b
Parent:
0:098463de4c5d 
changed the inputscale from 1 to 7 in analogin_api.c.  This will need to be changed later, and accessed from the main level, but for now this allows the  adc to read a value from 0 to 3.7V, instead of just up to 1V.;

Who changed what in which revision?
