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
Nasty 4-channel logic analyser using dsPIC30F4011
This post is about a quick and dirty 4-channel logic analyser that I hacked together to get a snapshot of four parallel binary signals from something I was building. I just want to quickly capture this information here for the … Continue reading

Short dsPIC30F4011 program to test output compare SFR values
I’ve been playing around with the output compare feature of the dsPIC30F4011 microcontroller for the last day or two and finding out some interesting things about it. There are two output compare channels (OC1 on pin 23, OC2 on pin … Continue reading
PWM Sinewave generation using output compare on dsPIC30F4011
Reader Manu Abraham wrote in with an interesting query about sinusoidal variation of PWM duty cycle using the output compare feature of the dsPIC30F4011. The 30F4011 has two output compare channels which can be used to very easily generate periodic … Continue reading

Using pk2cmd to transfer a hex file onto the dsPIC30F4011
Since upgrading to MPLAB X, I’ve had difficulty using the PICkit2 from within the IDE, so I’ve mainly been using the PICkit2 helper application to transfer my compiled hex files to the dsPIC. However, there is another handy way of … Continue reading
Creating a new XC16 project in MPLAB X
