Re-Post: iButtonLink T-Sense 1-wire sensor (Maxim DS18B20) + PIC 18F14K22

Using a PIC Microcontroller to pull temperature of iButtonLink T-sense sensor. I pulled this off the wayback machine because I lost this post in the great database loss of how ever many years ago. I’m re-posting because I’m working on an expanded version of this with an Arduino dev board and wanted a reminder of…

ESP32 Boot Camp

… for me. I got a rando e-mail offering me “free parts” and I usually don’t even bother opening the e-mail. It’s ALWAYS garbage right? Well, maybe I hadn’t slept well the night before but I opened it. (psss. You can scroll down about a page before I actually get anywhere in this post…) What…

MODbus/RTU on a PIC Microcontroller

By request one of my long lost blogs was a MODbus RTU application for a PIC 18F27J53. You could easily plop this onto many of the 18F series micros. It doesn’t do much but it’s a great stepping stone for throwing in your own IO. I’ll probably follow up with an Arduino version in a…
