Yes, it is possible to implement the 1-Wire protocol by using the UART hardware on a microcontroller. The 1-Wire protocol uses a single data line to communicate with devices, and the UART hardware on a microcontroller can be used to generate the timing signals required by the protocol.

To implement the 1-Wire protocol using UART, you will 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 implement the 1-Wire protocol using UART:

```
// Configure the UART hardware
uart_init(115200, 8, 1, 0);

// Send the 1-Wire Reset command
uart_write(0x55);

// Receive the 1-Wire Presence Detect response
byte response = uart_read();

// Check the response byte
if (response == 0x00) {
  // A device is present on the 1-Wire bus
} else {
  // No device is present on the 1-Wire bus
}
```

This is just a simple example, and there are many other ways to implement the 1-Wire protocol using UART. The specific implementation will depend on the microcontroller that you are using and the specific application that you are developing.
