I want to make a signal generator that control able by avr with below specification:
- 1 hz to 100 khz frequency
- square , sine , triangle, sawtooth waves
I search over and over whole internet and don't find a project can satisfy all up conditions and
I also try use of another IV beside avr such ICL8038 or XR2206 (but they are good to work with avr) and also AD9833 or AD9850 (but they don't generate sawtooth wave).
Can any one help me?
