Sure, I can give you some more information about the UART hardware on the Arduino Uno.

The UART hardware on the Arduino Uno is a simple serial communication interface that can be used to send and receive data between the Arduino and other devices. The UART hardware has two pins: TX (transmit) and RX (receive).

To use the UART hardware to implement the 1-Wire protocol, you need to configure the UART hardware to use the following settings:

* Baud rate: 115200bps
* Data bits: 8
* Stop bits: 1
* Parity: None

Once the UART hardware is configured, you can use it to send and receive 1-Wire commands. To send a 1-Wire command, you simply write the command byte to the UART transmit register. The UART hardware will then generate the appropriate timing signals to send the command on the 1-Wire bus.

To receive a 1-Wire command, you read the UART receive register. The UART hardware will return the byte that was received on the 1-Wire bus. The first bit of the byte will be the 1-Wire acknowledge bit, and the remaining bits will be the data bits.

Here is an example of how to configure the UART hardware on the Arduino Uno:

```
// Initialize the UART hardware
Serial.begin(115200);
```

This code will configure the UART hardware to use a baud rate of 115200bps, 8 data bits, 1 stop bit, and no parity.

Here is an example of how to send a 1-Wire command using the UART hardware:

```
// Send the 1-Wire Reset command
Serial.write(0x55);
```

This code will write the 1-Wire Reset command (0x55) to the UART transmit register. The UART hardware will then generate the appropriate timing signals to send the command on the 1-Wire bus.

Here is an example of how to receive a 1-Wire command using the UART hardware:

```
// Receive the 1-Wire Presence Detect response
byte response = Serial.read();
```

This code will read the byte that was received on the 1-Wire bus and store it in the variable `response`. The first bit of the byte will be the 1-Wire acknowledge bit, and the remaining bits will be the data bits.

I hope this information is helpful. Please let me know if you have any other questions.
