Hello, I need to drive a National semiconductor ADC converter ADC0808CCN (8 channels, 8 bits parallel output) with the DAQ1200 PCMCIA card. It seems to be very easy but I stock on this problem. I have an external clock signal that I would like to use to drive the clock of the ADC circuit and the CLKB1 DI port to produce a signal each eight pulse for the start convertion signal and to change each eight pulse the channel via the three bit address. I wired the start signal (also the enable) and the address signal on the PB DO ports. I can get data in continuous.
Does anybody have an idea of the ICTR Control vi to : 1) display the state of the external clock 2) making a start signal each eight pulse an write it to the PB2 DO
Is it possible to drive such digital pins like PB2 via an external signal at 150 [Khz] (divide by eight = 18.75 [KHz]) ?
Does anybody has an vi example of such acquisitions from external ADC circuit with DAQ1200 ?
