hai everybody....
im now using the adc0808 to convert the human voice into the digital form. but there is no output shown?? why??
where is the problem??
thanks for ur help
Also, you appear to have it wired to continually convert, as you are using a micro-controller you should use a signal from that to initiate a conversion, and wait for the end of conversion signal.
i program the bs so that it can direcly decode the input and producing the require output. but now im facing the problem in converting the huamn voice into digital form.....
two things..
1) the 0808 has no sample & hold circuit built in.. so you may want to use a different ADC.. or add one yourself..
2) as Nigel tried to tell you the interrupt ( or EOC ) is supposed to tell the uController when the conversion is done..
Hi guys,
the adc0808 is 8 bit adc with 8 multiplexed channels for analog signals.
its interfacing with microcontroller 8051 is very simple and easy, you can find code and other tips here on this link.
