DS2413(3)

💖 DS2413(3) — Dual Channel Addressable Switch 🎀

okay bestie, this is a section 3 page from the One-Wire File System (OWFS) manual, and it's all about the DS2413, aka the Dual Channel Addressable Switch. it's giving "tiny chip, big main character energy" ✨

🌈 SYNOPSIS 🌈

Dual Switch

3A [.]XXXXXXXXXXXX[XX][/[ PIO.[A|B|ALL|BYTE] | sensed.[A|B|ALL|BYTE] |
address | crc8 | id | locator | r_address | r_id | r_locator | type ]]

that's the whole vibe right there 💅

🦋 FAMILY CODE 🦋

3A — that's the family code, no cap.

✨ SPECIAL PROPERTIES ✨

🍓 PIO.A PIO.B PIO.ALL PIO.BYTE

• read-write, yes-no
• this is the state of the open-drain output ( PIO ) pin, fr fr. 0 = non-conducting (off), 1 = conducting (on).
• writing zero turns the switch off, and writing non-zero turns the switch on 🔥
• reading the PIO state gives you back the switch setting. but if you wanna know the actual logic level at the switch, go look at the sensed property, iykyk.
• ALL references both channels at the same time, comma separated.
• BYTE references both channels at the same time as a single byte, with channel A in bit 0.

🌸 sensed.A sensed.B sensed.ALL sensed.BYTE

• read-only, yes-no
• this is the logic level at the PIO pin. 0 = ground. 1 = high (~2.4V - 5V ). lowkey it really only makes sense if the PIO state is set to zero (off), else it'll read zero. 🙈
• ALL references both channels at the same time, comma separated.
• BYTE references both channels at the same time as a single byte, with channel A in bit 0.

👑 STANDARD PROPERTIES 👑

💜 address r_address

• read-only, ascii
• the entire 64-bit unique ID. given as upper case hexadecimal digits (0-9A-F).
• address starts with the family code
• r_address is the address in reverse order, which is often used in other applications and labeling.

⭐ crc8

• read-only, ascii
• the 8-bit error correction portion. uses cyclic redundancy check. computed from the preceding 56 bits of the unique ID number. given as upper case hexadecimal digits (0-9A-F).

🧚 family

• read-only, ascii
• the 8-bit family code. unique to each type of device. given as upper case hexadecimal digits (0-9A-F).

🎀 id r_id

• read-only, ascii
• the 48-bit middle portion of the unique ID number. does not include the family code or CRC. given as upper case hexadecimal digits (0-9A-F).
• r_id is the id in reverse order, which is often used in other applications and labeling.

🦋 locator r_locator

• read-only, ascii
• uses an extension of the 1-wire design from iButtonLink company that associated 1-wire physical connections with a unique 1-wire code. if the connection is behind a Link Locator, the locator will show a unique 8-byte number (16 character hexadecimal) starting with family code FE. if no Link Locator is between the device and the master, the locator field will be all FF.
• r_locator is the locator in reverse order.

💀 present (DEPRECATED)

• read-only, yes-no
• is the device currently present on the 1-wire bus?

heads up bestie, this one is DEPRECATED — it's still here, but it's giving "vintage," not "iconic." 💅

🌈 type

• read-only, ascii
• part name assigned by Dallas Semi. e.g. DS2401. alternative packaging (iButton vs chip) will not be distinguished.

🔥 ALARMS 🔥

use the set_alarm property to set the alarm triggering criteria.

💖 DESCRIPTION 💖

🌸 1-Wire

1-wire is a wiring protocol and 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. obsessed. ⚡

each device is uniquely and unalterably numbered during manufacture. there are a wide variety of devices, including memory, sensors (humidity, temperature, voltage, contact, current), switches, timers and data loggers. more complex devices (like thermocouple sensors) can be built with these basic devices. there are also 1-wire devices that have encryption included. 🔐

the 1-wire scheme uses a single bus master and multiple slaves on the same wire. the bus master initiates all communication. the slaves can be individually discovered and addressed using their unique ID.

bus masters come in a variety of configurations including serial, parallel, i2c, network or USB adapters.

✨ OWFS design

OWFS is a suite of programs that 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. 🗂️

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. there are some performance enhancements in the implementation, including data caching, parallel access to bus masters, and aggregation of device communication. still the fundamental goal has been ease of use, flexibility and correctness rather than speed.

🎀 DS2413

the DS2413 (3) allows control of other devices, like LEDs and relays. 💡 it differs from the DS2405 with a cleaner interface and two channels. the DS2413 also has two channels like the DS2406 and DS2407 but has no memory, and no alarm. there is also varying types of switch and sensing in the DS2408, DS2409, LCD, DS276x, DS2450.

unique among the switches, the DS2413 can switch higher voltages, up to 28V. 👑

---

🌟 ADDRESSING 🌟

all 1-wire devices are factory assigned a unique 64-bit address. this address is of the form:

• Family Code — 8 bits
• Address — 48 bits
• CRC — 8 bits

addressing under OWFS is in hexadecimal, of form:

01.123456789ABC

where 01 is an example 8-bit family code, and 12345678ABC is an example 48 bit address.

the dot is optional, and the CRC code can included. if included, it must be correct. ⚠️

and that's a wrap, bestie 🫶 this was OWFS Manpage, dated 2005, for DS2413(3) — go forth and switch some channels, you absolute icon 💅✨
