SDCC + PIC18 Assembly Manchester Encoding for Neutral RF DC Bias

Building on my previous post regarding inclusion of assembly language files in MPLABX projects that use SDCC for PIC18, I thought I would present a real-world example covering Manchester encoding of data to achieve neutral DC bias for RF applications. This seemed like the perfect example to use as the encoding of serial data is, […]

Microchip PIC Simple EUSART Serial Example

Sometimes, it’s nice to see an example of an implementation that is, otherwise, strewn throughout pages of a datasheet. I decided to pull some serial code out of a debugging file and provide it as an example to anyone who is having trouble getting their Microchip EUSART to perform correctly. The example is thoroughly documented […]

Maxim DS1620 Thermometer Output on Hitachi 44780 Example

Not long ago, I wrote a post regarding hardware and software interfacing a Maxim DS1620 Digital Thermometer/Thermostat. In my copious free time, I decided to follow through with a working example that displays temperature data on any LCD display that uses the ubiquitous Hitachi 44780 chipset. Below you’ll find a schematic as well as a […]

Maxim DS1620 Digital Thermometer Interfacing

Updated: For a working example, please read this post next. It provides schematic and software that will display the output of the Maxim DS1620 on any Hitachi 44780-compatible LCD. I was in the shop the other day, putting some FETs away and labeling drawers when I came across a drawer full of DS1620s. I have […]

Ultrasonic Range Measurement With PIC Assembly

I’ve been meaning to document project specifics as I develop in an attempt to share my software and provide an explanation as to how and why I chose a particular approach. I’d also like to provide readers with usable code that can be adapted to their own projects. Hopefully, this short article will be the […]
