Using a dsPIC30F4011 to generating 4 PWM signals with equal duty cycles but at 90 degree phase increments
In a recent comment on one of my blog posts, Saptarshi De posed an interesting problem: How can the dsPIC30F4011 be used to generate four PWM signals of equal (but variable) duty cycle at 90 degree phase increments? Saptarshi wants … Continue reading

First attempt at printing to an LCD display from a dsPIC30F4011
The following example is my first attempt at printing to an LCD display using the dsPIC30F4011 microcontroller. The display I’m using is a 16×1 character screen with what I think is a standard Hitachi interface. It’s my first time using … Continue reading
Simple interrupt-driven sampling example for the dsPIC30F4011
Reader Swetha wrote in with a query about performing 10Hz sampling on a dsPIC30F4011 in some kind of energy monitoring system. The following example illustrates a basic structure for interrupt-driven sampling using Timer 1. I compiled this program with Microchip’s … Continue reading
Updated version of IGBT control program for buck-boost dc-dc converter
This is an updated version of my IGBT control example for the dsPIC30F4011, which appeared in an earlier post. In this version, an analog control signal on pin AN6 is used to vary the duty cycle of the waveforms produced. … Continue reading
