Hello guys i need a working code for sine wave generation using pic 18f mcu

 

Easy.
Store a sine wave in a lookup table and output the data to a DAC.

 

Any example

Do you have any working code??I am a beginner

 

What is the Frequency of your Sine Wave?
How many Data Points per cycle do you require?

 

You also want to use a timer or clock to trigger the dac update, to avoid jitter
in the output waveform. An ISR can do this if its high priority, but thats not a
guarantee there will be no jitter. Only a HW process can guarantee that. There
are processors out there that can do an end to end HW solution. Not sure if PIC
can do this. Would have to have DMA. separate busses, and access to the sine
sample table.

Sine table values all over the net for download.

Google has a ton of examples.
Every one of these (that I looked at) has some version of "we need a better-formed/explained question"
