help.. newbie with ADC =)

hi..

is this (picture) will works..?

what signal should i put to ALE, START, EOC, OE ? 5v signal?

should i put resistors between ADC and LED ? 10K ?

and how to get direct output to the LED
while i give voltage input from variable resistor without changing ALE, START, EOC, OE ?
(when i turn the variable reistor, the LED changing automaticly)
connect OE with ALE? and START with EOC?


thanks..



sorry about my english =)

Which ADC is that ?
I wouldent connect your LEDs up that way. you should limit the current with some resistance..

Looks like ADC0808

0809

change your led's to at least 200 ohms per output line..
your clock frequency is a little high , it is within spec . but if you divide it by half with a flip flop you might be better off..
1) output enable you can tie that high ( in your case)
2) EOC is suppose to tell a uP when conversion is done but in your case , you can use a one shot ( or similiar device ) to send a signal from EOC to START and ALE..
