/***********************************************
File:Adcex2.c
Description:This example demonstrates the use of the TempBook/66's lower
level ADC functions. These functions allow separate scan
sequencer setup, trigger source selection, and ADC data collection.
Functions Used:bkSetMux(unsigned startChan, unsigned endChan, unsigned char
gain)
tbkSetFreq(float freq) tbkSetTrig(unsigned char trigger, unsigned char
oneShot, unsigned char ctr0mode, unsigned char pacerMode)
tbkRdNFore(unsigned _far *buf, unsigned count)
*************************************************/
unsigned int buf[80], scan, chan;
sprintf(response,"\r\nAdcex2.c\r\n");
/* Set the default mode of operation to single-ended bipolar */
tbkSetMode(0, 1);
/* Set the scan sequencer for channels 0 - 7 at unity gain */
tbkSetMux(0, 7, TgainX1);
/* Set the scan frequency for 1000 Hz */
tbkSetFreq(1000);
/* Set the trigger source for the Pacer Clock. Note that the trigger
is armed immediately */
tbkSetTrig(TtsPacerClock, 0, 0, 1);
/* Read 10 scans of data */
