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
