hi ,
i am interfacing ads1298 evaluation board with freescale controller.
1.i am able to READ AND WRITE the registers of ads1298
2.when i tried to read the channel data connected to internal test signal , i got DRDY toggling in inverted fashion as shown in datasheet and some parts is square wave pattern.
3.suggest me what clock phase and polarity to be used.
blue=DRDY
yellow=clock
i have attached the screen shot of waveform i got in oscilloscope.
thanks in advance.
regards,
shreedhara
