sirish Posted April 10, 2006 Report Share Posted April 10, 2006 Hi Friends,How can i interface standard adc chips like adc0800 or adc 0808 to the parallel port of the computer. My application has one analog input.Plz let me know which pins of the adc chips adc0800 or adc 0808 should be connceted to which pins of parallel port.Plzzzzzz help me.

windoze killa Posted April 10, 2006 Report Share Posted April 10, 2006 As far as which pins on the parallel port goes it will depend on your software that is going to read the port. Quote Link to comment Share on other sites More sharing options...
sirish Posted April 11, 2006 Author Report Share Posted April 11, 2006 i want to know where the pins soc(start of conversion) eoc ( end of conversion)and oe (output enable) of adc chips like adc0808 / 0800 should be connected to which pins of the parallel port.The D0-D7 pins of adc chips will be connected to d0-d7 pins of parallel port.I will be using visual basic 6 to read the data lines.

windoze killa Posted April 11, 2006 Report Share Posted April 11, 2006 Grab the datasheet for the chip. It should be easy enough to work out from there. For OE, SOC and EOC pins you should be able to use any of the control lines ie. busy line, for these outputs. Quote Link to comment Share on other sites More sharing options...
MP Posted April 15, 2006 Report Share Posted April 15, 2006 D0 is LSB and D7 is MSB on Parallel port. Is this what you wanted to know? D0 on Parallel port connects to LSB on the ADC0808.MP Quote Link to comment Share on other sites More sharing options...
