Because of the sensor offset, I added just 2 lines of code. The offset is about 0.6V and the sensor has a slope of 60mV/A.
It is directly connected to the "Cur" Pin on the Rushduino board (only a LPF is added 330Ohm/10µF). I haven´t checked the consumption over time, but the values in the OSD have been tested against a multimeter for correct readings.Code: Select all
const int amperageOffset=123; //ACS755 Offset
..
..
rawamperage = analogRead(amperagePin)-amperageOffset;
if(rawamperage<0) rawamperage=0;
amperage = (float(rawamperage))/1.23;
I´m going to try with MWC info thru powermeter, but Allegro is on my wish list for Christmas
