tcDspAdc9235

Introduction

The tcDspAdc9235 class may be used to provide access to the MityDSP ADC9235 interface core. The ADC9235 interface core marries the MityDSP to a Analog Devices 9235 series high speed 12 bit analog to digital converter.

This class allows for configuring the ADC to provide continuous or burst data collection data.

Example

This is a simple example of tcDspAdc9235 creation and usage:

 {
     tcDspAdc9235* mpADC;
     int numwords;
     volatile unsigned int* lpData;
     unsigned int tmp, index;

     // new up the ADC9235 core.
     mpADC = new tcDspAdc9235((void*)BASE_ADDR);

     // burst capture of 512 samples
     mpADC->Enable(false);
     mpADC->DrainFIFO();
     mpADC->SetBurstCapture(true);
     mpADC->SetCaptureLength(512);
     mpADC->ClearBurstComplete();
     mpADC->Enable(true);
     mpADC->SetPack(false);

     while(false == mpADC->IsBurstComplete());
     mpADC->Enable(false);    
     numwords = mpADC->GetFIFOLevel();
     lpData = mpADC->GetFIFODataPtr();
     index = 0;
     while(false == mpADC->GetFIFOLevel(eeEmpty))
     {
        tmp = *lpData;
        printf("%d - %8.8X\r\n",index,tmp);
     }
     
     ... 

 } 

Note:

When using packed mode, the burst capture length must be even.
