The keypad is programmed over 300 baud modem via the Win98 software CJWin32. While it is possible to run this software under a VM on my Mac, I wanted to try building a replacement as an excuse to learn PCB design. It would absolutely be trivial to replace the gate computer with a Raspberry Pi or similar, but that would defeat the point of the project as an educational exercise.</p>https://farad.space/posts/homekit_accesory/Tue, 08 Dec 2020 21:32:54 -0800https://farad.space/posts/homekit_accesory/<h2 id="overview">Overview</h2> <p>Over the past 8 weeks, I built a HomeKit accessory to open and close the gate at the end of my driveway. The project was really fun, and this document outlines the process of creating it, from concept to working prototype.</p> <h3 id="additional-background">Additional Background</h3> <p>Programming examples for microcontrollers will be in C++. For the most part, we’ll be sticking essentially to “C with Classes”, which is typical of most Arduino and other microcontroller projects.</p>
