Hi everyone!

I have to design a BPSK modulator via AVR and DAC..


the function must be like this : when PB0 is at "Low" level we must have a Sinusoidal wave with 0 degree phase at the output of DAC

when PB0 is at "High" level we must have a Sinusoidal wave with 180 degree phase at the output of DAC..

I've decided to use DAC0800 as my digital to analog converter. and I know how to use an avr chip and program it in C language.

but I want to know the algorithm and how to use DAC0800..
the datasheet of DAC0800
http://eedept.ncue.edu.tw/study/labs/semilab/Experiment_Data/Experiment_data_sheet/DAC0800.pdf

can anybody help ?

 

there isn't any idea???

 

?????????

 

Hello,

You are saying that you want to switch the phase of a signal with an output of the AVR.
How do you want to generate the signal itself?

Hello

I want to generate the signal via DAC0800 . look at the device datasheet at the first post.. I cant understand it
