Josip Retro Bits | Measure Temperature with Commodore 64 @JosipRetroBits | Uploaded July 2023 | Updated October 2024, 4 hours ago.
In this video, we connected DS18B20 digital temperature sensor to Commodore 64. Then we learned how the 1-wire protocol works and implemented the same in assembly. In addition, you will see how I dealt with floating point numbers in assembly. Enjoy :)
