NCDLib – Random Code for Controlling NCD Devices

Sometimes I like to write code to simplify my life, particularly when I need to call the same routines over and over.  Over the years, I have pieced a few code elements together to help make the NCD Component Library easier for me to use.  Some of this code is old, some is new, some is tested heavily, and some of it is random ideas I have had over the years.  A recent post on the forum prompted me to release the code, as I have been meaning to do this for a long time anyway.  This code represents a

Maximizing Performance of NCD ProXR Relay Controllers

ProXR controllers have been the standard for relay control applications for many years.  Over the years, we have improved firmware to add functionality.  Several years ago, we migrated from a PIC16F690 processor to a PIC18F46K22 processor, which has more memory and runs 4 times faster.  After this migration, we found it necessary to slow down the CPU to safer levels, as older software was not able to handle the ultra-low latency of the new CPU.  NCD ProXR relay controllers have the ability to perform much faster by tuning a few settings.  This guide will help you get the most performance

Unable to Mount Virtual COM Port in Windows 10

Unable to Mount Virtual COM Port in Windows 10 If you are using Windows 10 (or any other operating system) and having problems getting a Virtual COM Port to be assigned to your system, follow these steps.  We recently discovered after a Windows 10 Update, that Virtual COM Port drivers may not load any-longer by default for some devices. If you are unable to use Base Station or AnyI2C software because the COM port is not showing up, here’s an easy fix: Prerequisite: VCP Driver Installation Recent operating system updates, hardware (VCP Chip) revisions, and VCP drivers may prevent a
