tcDspAdc1278

Introduction

The tcDspAdc1278 class may be used to provide access to the MityDSP ADS7844 interface core. The ADS1278 interface core marries the MityDSP to a TI ADS1278 series 24 bit analog to digital converter.

For hardware interfaces, the ADS1278 and McBSP should be connected as follows:

McBSP Port	<ADS1278 Port	Notes
DX	DIN	External 2K Pulldown Resistor required
DR	DOUT
CLKX	DCLK
CLKR	No Connect
FSX	No Connect
FSR	BUSY
Ground	CS

Example

This is a simple example of tcDspAdc1278 creation and usage:

 {
     tcDspAdc1278* mpADC;
     unsigned int sample[32];

     // new up the 1278 core.
     mpADC = new tcDspAdc1278(MCBSP_DEV0);

     // read samples, print results
     while(true)
     {
        sample = mpADC->GetSamples(sample, 32);
        for (int i = 0; i < 32; i++)
        {
           printf("[%d] - %d\r\n",i,sample);
        }
        TSK_sleep(1);
     }
     
     ... 

 }
