Plz Help Me to do A/D and D/A

i knew embedded programming in c51 and iar but i don't knew how we can do A/D and D/A conversion with eg programs

Hi,
Will you please elaborate your problem. A/D conversion is not possible with software. D/A conversion can be done.
A/D Conversion:
Signals in analog form are not discrete, hence they can't be stored. Since they can't be stored they are sampled and converted to digital form.
D/A conversion depends on the quantizer step-size used in A/D conversion. You only de-quantize and keep the signal in digital form. And then u pass these signals to D/A converter hardware unit.

Bye,
Prashant Adkoli

hi,
through s/w u cant convert but if u want to that through h/w with no pain then chek out Intrsil Corporation,s 7135 for A/d conversion

: hi
you need you inetialise the A/D first and then the chip selection pind of A/D should be conned to the microcontroller and the data lines of the A/D should be connected to the data line of microcontroller through latch
and chip selection is must which yu can select either by decoder or by PAL programming
if clearly explain your design i can help you in this aspect
thanks and regards
