Using UART with Raspberry Pi Pico using MicroPython

Today, we’re diving into the world of UART communication using MicroPython on the Raspberry Pi Pico.
This session is all about showing you how to set up and run UART connections like a pro.
Once you wrap your head around these concepts, you’ll not only level up your embedded systems skills but also snag some hands-on experience along the way.
So, get ready to enhance your tech toolkit!.

Setting up UART connections is pretty straightforward! First things first, you’ll need to use pin Y10 for RX and Y9 for TX with a UART to TTL converter.
Make sure you have secure connections with jumper cables that have female connectors on both ends.
Don’t forget to add a ground wire to one side of your setup to keep everything running smoothly.
For wiring, the black wire should go to the GND terminal, while the white wire from Y10 (RX) should connect to the TX pin.
Meanwhile, Y9 (TX) needs to connect to the RX pin on the other end to nail down that communication setup.
Finally, double-check that all connections are spot on to ensure effective communication throughout your project!.

So, let’s dive into how the UART communication code kicks off! First, it starts by grabbing the machine module and decides to use UART 1 for setting up the communication interface.
Next up, it sets the baud rate to 115200, which is a pretty standard speed for transmitting data, and it even prepares a handy reference message saying “hello device SMT”.
Now, it’s super important to get the pin configuration right: TX goes to Y9 and RX fits into Y12 , ensuring those physical connections for smooth data transfer.
The code also keeps an eye out for incoming data, checking if there’s anything coming from the connected device, which helps it respond quickly.
And when data is detected? The system is all set to read up to 128 bytes and print out whatever text it received, showing just how those code conditions come into play in a real-world scenario!.

Getting started with MicroPython code execution is super simple! First off, you connect everything and run the program, and you’ll see it in action right away.
Once you link up with the Arduino serial monitor, the fun begins as it communicates seamlessly, flashing a friendly ‘hello device SMT’ message to show that data is flying back and forth.
Curious about what’s happening? You can even send your own message, like ‘nice to’, and watch as it pops up on your screen, proving that the communication process is crystal clear.
On the Raspberry Pi Pico, you’ll be using pins 9 and 10 to read in data—specifically 128 bytes from whatever device you’ve got connected— and then it shows that data right on the console for you to check out.
So, this whole practical setup really breaks down how to get UART working on the Raspberry Pi Pico with MicroPython, making it easy for everyone to get the hang of it..

In this session, we dove into the world of controlling the UART on the Raspberry Pi Pico using MicroPython.
It was a great way to get hands-on experience with pin configurations and data transfer techniques.
By the end, we had a solid grasp of how to set up and operate UART connections like pros.
Plus, we walked away with a better understanding of how practical application can boost our embedded systems skills.
And don’t worry, this learning journey isn’t over yet; we’ll have even more exciting content in our upcoming sessions!.
