Unleashing Tio: Serial Communication on Raspberry Pi Pico 2
Guideline for Employing Tio: Linking Serial Devices with Linux Operating System
Ready to bring that vintage charm to your tech game? Let's dive into using Tio, the trusty old-school tool for managing serial connections, with your Raspberry Pi Pico 2.
Tio Installation
Before we get started, make sure you've got Tio installed on your Linux system. If not, you can whip it up in a jiffy through your package manager:
Now, let's get this show on the road!
3V3 Out
Raspberry Pi Pico 2 Demo Circuit
Pin 1 (VDD)
First, connect your Raspberry Pi Pico 2 to your Linux box via USB. Once it appears as a serial device, we'll locate its path. Use this snazzy command to list all available serial devices:
3V3 Power
Red
This will output something like . Hang tight; we'll use thatPath later.
Connecting to the Serial Device with Tio
GPIO 17
Time to connect with Tio! Open up your terminal and follow these simple steps:
Pin 2 (Data
- Connect using Tio: Use the following command to connect at the default baud rate:
Data out
To kick it up a notch, you can specify a custom baud rate using the option:
Orange
Here, we've boosted the baud rate to 115200.
Logging Serial Data to a Text File
Any GND
Keeping a record of your data is smart, and Tio makes it easy to do just that. To log serial data to a file, redirect the output using the operator:
Pin 4 (GND)
- Run Tio and Redirect Output:
Ground (GND) reference
This will save all your serial goodness to .
Black
- Stop Logging: Press to break the connection.
Interactive Mode and Closing Tio
- Enter Interactive Mode: Press while connected to drop into an interactive mode where you can enter commands.
- Close Tio: To properly exit Tio, press , followed by .
Example Code on Raspberry Pi Pico 2
Using MicroPython on your Raspberry Pi Pico 2? Here's a lean, mean temperature-reading machine with the DHT11 sensor:
```pythonfrom machine import Pinimport timeimport dht
sensor = dht.DHT11(Pin(17))
while True: time.sleep(2) sensor.measure() temp = sensor.temperature() print("Temperature Checker") print('The temperature is:', "{:.1f}ºC\n".format(temp))```
From now on, your Raspberry Pi Pico 2 will spit out its temperature readings, and Tio will be ready to catch 'em all! Keep rocking that retro charm, tech-ninja style!
In the process of setting up serial communication with the Raspberry Pi Pico 2, it's essential to have Tio, a data-and-cloud computing technology, installed on your Linux system. You can install it using the package manager:
Furthermore, when interacting with the serial device using Tio, the technology plays a crucial role in connecting, parsing, and even logging data. For instance, to log serial data to a text file, you can redirect the output using Tio:
- Run Tio and Redirect Output:
Tio facilitates a seamless and interactive experience with your Raspberry Pi Pico 2 in the realm of data-and-cloud computing.
