RC Analog

[Slick]

Thanks. I'm using the new code from Kevin. When I put
Get_Analog_Value(rc_ana_in01); in my code I get errors. Can you show me a small loop to achieve this. Thanks again.

Kevin's code uses a different method. Use Get_ADC_Result instead and make sure to choose the right options in adc.h.

It's also important to note that Get_ADC_Result uses just the number (1, 2, 3 etc...) not rc_ana_inXX

So instead of

Get_Analog_Value(rc_ana_in01);

you'd write

Get_ADC_Result(1);

You'll also need to enable the ADC in teleop.c and enable the ADC timer in ifi_frc.h

Tried the Get_ADC_Result(1); and it does not compile. Went to the old code and used Get_Analog_Value(rc_ana_in01); and it does compile. I'm using the printf to see my value: example: printf ("Analog 1 = %i \r\n"' rc_ana_in01); and I'm not getting any readings from my IR sensors. I fell very confident the sensors are working correctly and I have it plugged to the Analog one port on the RC. What am I doing wrong??? How can I get the analog reading? Thanks for all of the help so far and I feel close to solving this problem.

We use the following lines to read an ultrasonic sensor...

uProximityRaw = Get_ADC_Result(RHS_PROXIMITY_LEFT);
uProximityMv = Convert_ADC_to_mV(uProximityRaw);

... and it absolutely works. So you must not have Kevin's ADC stuff set up correctly. If this does not compile, make sure that adc.c is in your project, follow the directions in adc.h for configuration and make sure to put the following line in all source files where you call Get_ADC_Result(x).

#include "adc.h"

That was it.. Thanks to all. You guys are "THE MAN"...
