1WIRE Mode

This mode allows communication with devices using the 1-Wire protocol, such as iButtons or temperature sensors (e.g. DS18B20).
It supports basic scanning, reading, writing, and sniffing features.

🧩 Commands

Command	Description
`scan`	Detects and lists all devices found on the 1-Wire bus with their ROM IDs
`ping`	Sends a reset pulse and checks for presence response from a device
`sniff`	Passively monitors the data line, detecting timing patterns (reset, presence, bits)
`read`	Reads both the ROM ID and scratchpad of a connected device
`write id <8 bytes>`	Programs a new ROM ID to a supported device (RW1990 compatible)
`write sp <8 bytes>`	Writes 8 bytes to the scratchpad memory (via 0x0F command)
`temp`	Reads and decodes the temperature from a connected DS18B20 sensor
`config`	Lets you change the data pin used for 1-Wire communication
`[0xAA r:8]` ...	Allows sending manual 1-Wire instructions with precise control over command flow

📝 Notes

You can use scan to discover devices like DS18B20 or iButtons.
The read command shows the device's ID and scratchpad if supported.
The write id and write sp commands expect 8 bytes in hex format (e.g. write id 01 02 03 04 05 06 07 08).
The write id implementation follows the official Dallas 1-Wire protocol for ID programming, including the proper timing sequence and command structure.

⚠️ It may not work reliably on inexpensive clones or non-Dallas chips
sniff is useful when passively monitoring a 1-Wire bus connected to another master device. It attempts to automatically detect known 1-Wire timing patterns, including reset pulses, presence responses, and bit-slots, to reconstruct readable transactions.
The instruction syntax ([0x... r:N]) allows precise control of low-level communication, including bit-level reads, delays, and raw hex sequences.
