Hello,
mirc84:
I am using the core posted here https://github.com/mchr3k/arduino-libs-manchester/downloads by mchr3k. I did so in order to get the Manchester library working.
It's a slightly older version of core available here...
http://code.google.com/p/arduino-tiny/
There is nothing "Manchester library" specific in it.
//Set current input pin
int inPinI = 1;
...
sampleI = analogRead(inPinI);
You are reading from ADC1. This is PB2 / digital pin 2 (right side of chip, second pin from the top). Is that where the sensor is connected?
