The setup_adc_ports() function is used to do this.
Look at the settings for the setup_adc_port() function in the 16F72.h file.
Here is the file location:

i have define the adc_port to 7 value, but still i unable to set PORT A to digital out.
#byte port_a=5 //address of port a
#define ALL_DIGITAL 7 //setting digital output.
setup_adc_ports(7);
port_a=0xFF; |

| Code: |
#include "16F72.h"
//Put your clock definitions, and fuses here
void main(void) {
setup_adc_ports(NO_ANALOGS);
output_a(0xFF);
//Rest of code
while(TRUE);
}
|
Note the use of the 'output_a' function, rather than writing directly to the port latch. You _can_ write directly to the latch, but if you do, _you_ also need to control the TRIS register. The CCS function does this for you.
