Help! Analog Inputs!!
 

Were using a potentiometer and I have no idea how to read the potentiometer value!

PLease help

Re: Help! Analog Inputs!!
 

Simply plug your POT into a analog port

Then use Get_Analog_Value(rc_ana_in0*)

Where * is the number port you placed the POT.

It will return a value between 0 and 1024, depending on how far it has been turned.

So i just printf("Pot %d\r", Get_Analog_Value(rc_ana_in0*)); to display it?

Yes that should do it.

Re: Help! Analog Inputs!!
 

Well, to clarify, you would replace * with the number of the analog input you put the potentiometer into. For example, if you plugged the potentiometer into analog input 1, you would put
But you may have already known that.

It doesn't really matter in this case, but when using an unsigned value, like analog inputs, you should use %u and not %d (the ADC conversion gives you a 10-bit value, 0-1023, so it should never come up as negative, but it's good to know in case you need a full 16-bit unsigned int).

Just make sure that the pot is properly connected (red + black leads to the outer leads on the pot, white to the wiper/middle lead) and you should have no problems. Our arm potentiometer got disconnected during testing and its value started creeping by 1 every few seconds, it was really weird. O_o

Also, make sure you've included ifiutilities.h in whatever file you're using Get_Analog_Value() or else it won't work. o_o

Yep, Get_Analog_Value('the analog input number').
