Anonymous Poster	Choosing Between PWM Chip and Microcontroller to Generate PWM Waveform? 01/08/2008 7:27 AM
	hi, I wonder if either a PWM chip or microcontroller is easier to generate sinusoidal PWM waveform? I have written a program that produces PWM waveform in MATLAB, but I don't know if i can connect it to a microcontroller to generate exactly the same waveform as in MATLAB? If so, how can it be done? thank you.

	It depends on the frequencies you require. I believe there are some good waveform generator chips which may be a more appropriate starting point. A micro-controller could well be a bit slow? Have you got development kit for a microcontroller? __________________ health warning: These posts may contain traces of nut.

	the frequency i require is 50hz.i am not sure what is the developement kit for microcontroller. by the way, how to connect a MATLAB program to a microcontroller?

	how to connect a MATLAB program to a microcontroller? No idea!... If I wanted 50hz, I'd just use mains frequency via a transformer... Where are you? What is your mains frequency? What do you want to do with the 50 hz...? __________________ health warning: These posts may contain traces of nut.
