sirish Posted April 5, 2006 Report Share Posted April 5, 2006 Hi Friends,Can i design a ADC ckt that can be directly interfaced to the parallel port of the computer.Plzzz i am looking out for the adc ckt that can be interfaced directly.**********Suppose if i use avr controller for adc then can anyone give me the sample code that reads the analog input and then giving the output of avr controller to the parallel port of the computer.I am dummy as far as microcontrollers are concerned.Plzzzzzzzz help me.

windoze killa Posted April 5, 2006 Report Share Posted April 5, 2006 You don't need to use an AVR or PIC. There many many ADC and DAC chips on the market. Analog Devices has heaps that will do the job. Browse their site for datasheets. Quote Link to comment Share on other sites More sharing options...
sirish Posted April 6, 2006 Author Report Share Posted April 6, 2006 Thanks for the reply.But for ADC Chips like adc0808 i will have to interface with microprocessors which i don't want.I am looking out for ADC circuit that can be directly interfaced to the parallel port.Plzzzz help me.

windoze killa Posted April 6, 2006 Report Share Posted April 6, 2006 ADC chips like that can be interfaced directly to the port. You may need a buffer chip for some of them. You should then be able to read the data from the port with some software. Quote Link to comment Share on other sites More sharing options...
