I want to test a very simple code, insamp (with two PGA and one ADC). When I run the code, it stop in the line:

if (ADCINC_1_fIsDataAvailable() != 0);

Below is the code, can anyone tell me what wrongs, thankks a lot in advance!

#include <m8c.h>        // part specific constants and macros
#include "PSoCAPI.h"    // PSoC API definitions for all User Modules
#include "PSoCGPioInt.h"

int  iResult;

void main(void)
{
    PGA_1_Start(PGA_1_HIGHPOWER);
    PGA_2_Start(PGA_1_HIGHPOWER);
    ADCINC_1_Start(ADCINC_1_HIGHPOWER); /* Turn on ADC power */
    ADCINC_1_GetSamples(0);            /* Sample forever */
   
    while(1) {
     if (ADCINC_1_fIsDataAvailable() != 0) /* If ADC sample is ready... */
     { 
         iResult = ADCINC_1_iGetData() + 2048; /* Get result, convert to unsigned and clear flag */
         ADCINC_1_fClearFlag();
     }
 }
}

The general system setup as below:

VC1=sys/3

VC2=VC1/8

VC3=sys/1

 Analog Power: SC on/RefH

RefMax:Vdd/2+/-BandGap

OpAmp bias Low

A-buff_power low

Switch Mode Pump OFF

Trip Voltage LVD4.81V

Including is my project codes.

Hi JimL,

Can you please repost the question in PSoC1 topics of the forum?

In this space, PSoC5 topics are discussed.

JimL,

You  need to enable Global Interrupts for the ADC to work.  Add the code "M8C_EnableGInt;" in main.  See if this fixes the problem.  Also, check out my blog post PSoC1 ADCs - The Five Golden Rules that talks about best practices to get the ADC working without any problem.
