hi!
At first sorry for my bad language! Please help me someone because i am a begginer in AVR library. In Arduino i have a good knowledges! I need to generate a 3 phase sinewave with 60 degree offset! I find how to generate a sinewave http://interface.khm.de/index.php/lab/experiments/arduino-dds-sinewave-generator/ but in this programm is used a "avr/pgmspace.h" library and i in it didn't un derstand, where is what! I didn't understand even vhere is in program initializet from witch pin is output signal! I just read it in specification, but in program i can't find! Can someone help me PLEASE?

Look here:-

to find where to down load it from and what it does. You need to put it in your libraries folder when you get it.

Hi,
Did you carry out your job successfully ?
Is it possible to have a 120° offset instead of 60° with your Arduino based on what you already done ?
See ya.

Yes it is a simple matter of adjusting the second readout pointer to point at one third through the lookup table instead of one sixth.
