16F916 and setup_adc_ports
PostPosted: Wed Dec 07, 2005 3:59 am     Reply with quote
Dear,

PCWH 3.236
MPLAB 7.22
PIC16F916

Code:

setup_adc_ports(RA0_ANALOG);


results in : Undefined identifier RA0_ANALOG

using

Code:

setup_adc_ports(AN0_ANALOG);


is the same.

Any ideas what is wrong?

best regards

I have not tested the code, but if you look at the 16F916.h file (find it in the c:\program files\picc\devices folder), you get:

Code:
// Constants used in SETUP_ADC_PORTS() are:
#define sAN0            1       //| A0
#define sAN1            2       //| A1
#define sAN2            4       //| A2
#define sAN3            8       //| A3
#define sAN4            16      //| A5
#define NO_ANALOGS      0       // None
#define ALL_ANALOG      31      // A0 A1 A2 A3 A5


Modify your code as:
Code:
setup_adc_ports(sAN0);

and test it.

Best regards.

Paolo.
