Anybody has a digital function generator ?

[vlamish]

Hi all,

my aim is to build a ‘digital function generator’ .
Waveforms:
• Sine
• Square
• Triangle
• Sawtooth

The waveform must be selected with a ‘switch’ .

The frequency of the signal must be adjusted with an analog input signal.

There is no requirement to adjust the amplitude of the signal.

Using PIC2kit. MPLAB. C programming

Any codes, please ? Would be very grateful )))

You're not going to find anything ready made exactly to your specifications, but here's a good start!.

hi,
Have a look at the XR2206 ic.
