1-WIRE

1-Wire is a half-duplex protocol that uses one data line plus a ground reference. It is asynchronous: specific timings tell the commands apart. Like I2C, it is open-drain at the hardware level.

Settings

Within this segment, users can opt to use internal pull-up resistors if available in the host adapter. Accessing the Command dropdown menu reveals available ROM Commands: SKIP and SELECT (often referred to as MATCH). The SKIP command broadcasts a message to all connected target devices, while the SELECT command communicates with a specific device. If there’s only one target device on the 1-Wire bus, these commands are disregarded. The SCAN button initiates a series of SEARCH commands, unveiling the 64-bit addresses of all target devices connected to the bus.

Transfer

This segment features two inputs: ‘Bytes to Read’ and ‘Bytes to Write’. It also includes three action buttons: READ, WRITE, and TRANSFER. As with other protocols, the ‘Bytes to Write’ field recognizes bytes in hexadecimal format. Activating the TRANSFER button initiates a Write action, immediately followed by a Read action.
