You propose to make analog sine wave without external filtering ? I can worry about the filters and everything else later.Ĭonsidering that the PIC you're using only has i/o ports and 2-level (highĪnd low) hardware PWM, and can't make an analog waveform, how do What my professor said is that for now I should just focus on getting a sine wave output on labVIEW and that I can worry about the filters and everything else later. Is this a school assignment ' i did it' project More data needed before we can really help. This is what is commonly used to simulate sinusoids for things like synchronous motors.Ĭhoose a PIC with a DAC, and as PCM_programmer points out you can then get a 'stepped' sinusoid.Īdd a better DAC, and the step sizes get smaller. However to give an actual sinusoidal waveform from this, requires hardware filtering. The 18F46K22, it has a DAC with 32 levels.Īnd (of course), a lot depends on what you actually want to 'do' with the resulting sinusoid.įor instance, in terms of 'power delivery', you can get a sinusoidal behaviour using a modulated PWM. Thanks.ĭo you have to use that PIC ? It doesn't have a built-in DAC. I am new to programming microcontrollers so I am not sure where to start. I want to write a code that re-creates the same sine wave on CCS C so I can output it on labVIEW. I have the PIC hooked up to a function generator so I can see the sine wave on the oscilloscope. I am using a PIC18f6722 microcontroller and I want to generate a sine wave at 60Hz.
