6 hours ago It only has two UART methods, where an example like i2c.py or spi.py has several. The example above also defines a class. Many people new to the Pico and/or Python probably do not know that "self.any()" refers to UART. No offense @ukscone, I just think the official example for UART should be more "Python basic" and cover more UART functionality.

Frequently Asked Questions

How do I create a UART object?

UART objects can be created and initialised using: Bits can be 5, 6, 7, 8. Parity can be None, UART.EVEN or UART.ODD. Stop can be 1, 1.5 or 2. A UART object acts like a stream object therefore reading and writing is done using the standard stream methods: To check if there is anything to be read, use: class machine.UART (bus, …)

How do I get Started with MicroPython?

Let’s get started! The first thing you need is a board with an ESP32 chip. The MicroPython software supports the ESP32 chip itself and any board should work. The main characteristic of a board is how the GPIO pins are connected to the outside world, and whether it includes a built-in USB-serial convertor to make the UART available to your PC.

How to program a Microbit board with upython?

For this tutorial I’m using version 1.7.0 of uPython for the Micro:bit board. We will start our code by importing the uart object and the sleep function, both from the microbit module. Then we will initialize the serial interface, using as Rx and Tx the micro:bit external pins 1 and 0, respectively. We will use a baud rate of 9600.
