RESOLVED - emonGLCD breakout pins?

Submitted by mattnj on Thu, 09/05/2013 - 10:08

I am trying to find 2 pins to use on the back of the emonGLCD, I need 1 x digital, 1 x analog....

I can't work out how to identify the pin numbering from the schematic at:-

I was hoping to use pin2 and pin5 on the jeeport expansion as DIG8 and ADC2....

I have referncenced them as :-

const int pump=8;
const int motorspd=2;

then

pinMode(pump, OUTPUT);
pinMode(motorspd, OUTPUT);

and

if blah blah then

digitalWrite(heatpump, HIGH);
analogWrite(motorspd, 200);

} else {

digitalWrite(heatpump, LOW);
analogWrite(motorspd, 0);

the digital one seems to sort of work ok, it switchs on/off ok but I get a low voltage, between 1.7v > 2.4v (on a multimeter)

if/when I add the code above for pin2 the emonGLCD crashes and doesnt work at all?

Help please, are these even the right pins to use, and are the numbers (8,2) I am using right?

Thanks

I answered my own question with trial and error:-

const int pump=8; //DI06 on GLCD marked as Jeeport
const int motorspd=4; //Pin17 on the GLCD (strip at the bottom)
