πΈ DESCRIPTION πΈ
okay bestie, welcome to DESCRIPTION(1so) β this is the page that explains what the heck 1-Wire even is, and honestly it's giving iconic hardware lore. β¨
1-Wire is a wiring protocol and a series of devices designed and manufactured by Dallas Semiconductor, Inc. The bus is a low-power, low-speed, low-connector scheme where the data line can also provide power. like, the same wire does both?? lowkey obsessed. π₯
Each device is uniquely and unalterably numbered during manufacture β a permanent name, fr fr, no changing it later.
There are a wide variety of devices, including:
- memory
- sensors (humidity, temperature, voltage, contact, current)
- switches
- timers
- data loggers
More complex devices (like thermocouple sensors) can be built with these basic devices. π There are also 1-wire devices that have encryption included β fancy.
The 1-wire scheme uses a single and multiple on the same wire. The bus master initiates all communication. The slaves can be individually discovered and addressed using their unique ID. π«Ά
Bus masters come in a variety of configurations including:
- serial
- parallel
- i2c
- network or USB adapters
π¦ the programs part π¦
Then there's the suite of programs, designed to make the 1-wire bus and its devices easily accessible. The underlying principle is to create a virtual filesystem, with the unique ID being the directory, and the individual properties of the device are represented as simple files that can be read and written. literally so clean it hurts. π
Details of the individual slave or master design are hidden behind a consistent interface. The goal is to provide an easy set of tools for a software designer to create monitoring or control applications. π
π performance stuff (yes, it exists) π
There are some performance enhancements in the implementation, including:
- data caching
- parallel access to bus masters
- aggregation of device communication
Still, the fundamental goal has been ease of use, flexibility and correctness rather than speed. periodt. π
note: speed is not the main character here β ease of use, flexibility and correctness are. keep that in mind before you go benchmarking anything, bestie.
and that's the whole vibe of DESCRIPTION(1so) π β go build something cute with a sensor, mwah πβ¨
