I am very new to this hardware and C programming. I just purchased the Uno32 with an AnalogShield. I am running the Passthrough program which works. I would like to also display the input voltage but I am not able to calculate from the digital number that I am getting. At 0V, I get -32693 counts. At 1.587V (AA battery), I get -22377. At -1.587V, I get 22533. At -3.127, 12159. AT 3.167, -11989 counts. So at lower voltage, I get higher counts. I think this is lack of knowledge on my part; hopefully someone can help me out. Thanks! int count = 0;float val = 0;void loop(){ count = analog.read(0); //read in on port labeled 'IN0' //count = count; float voltage=count*(5.0/65535.0); val = map(count, -32768.0, 32768.0, 0.0, 5.0); analog.write(0, count); //write out the value on port labeled 'OUT0' Serial.println("count "); Serial.println(count); Serial.println("map -32768, 32768, 0, 5"); Serial.println(val); Serial.println("Voltage as 65535 over 5V"); Serial.println(voltage); Serial.println(" "); //Serial.println("count"); //Serial.println(analog.read(1)); //Serial.println("voltage"); //Serial.println(v); delay(10000);}
