Re: Lab X1 and 16F877 examples for beginners
Hi ! demon
I want to generator 3 Phase spwm signal for my final year project but I, m started by understanding single phase SPWM by reading the example from
Microchip appliction notes for sine wave with the 16F series chip..http://ww1.microchip.com/downloads/e...tes/00655a.pdf together with the examples given in http://www.picbasic.co.uk/forum/cont...wave-using-DT- interrupts and http://www.picbasic.co.uk/forum/showthread.php?t=14359.
there are number of things which i've not understand from these readings and i'm asking for help from anyone who can help me to understand.these things are:
1)which formular used to generate a lookup table for the sine waveforms
3)what is the purpose of this piece of code and how to get this values from example of http://www.picbasic.co.uk/forum/cont...-DT-interru and
TMR2 = 117
PR2 = 63
TMR1L = 255
TMR1H = 254
