Hi friends,
I am trying to implement ADC module of 16F676 in MikroC. Please see the code below. A LED, connected to RA5 of MCU is made ON/OFF depending on the value of analogue input to AN4 of MCU. I have tested the hardware developing the code in assembly. But when I try to develop the code in MikroC, it does not work. No effect is seen in output (RA5) while varying the input analogue voltage at AN4. Please suggest an way out.

Code:
int g_volt;
void main() {
TRISC = 0x00;
TRISA = 0x7;
ANSEL = 0x30;
CMCON = 0x7;
do {
g_volt = ADC_Read (4); // Take adc at channel AN4
if (g_volt > 108)
PORTA= 00100000; // Turn ON LED at RA5
else
PORTA= 00000000; // Turn OFF LED at RA5
}
while (1);
}
