![]() To be able to do so, the firmware needs to implement a python interpreter which understands python code syntax, translate it to machine code, then execute it.Output will be sent back to the terminal via UART. Upon receiving this code, the firmware will interpret your code and execute code line-by-line.Your code will be sent to ESP32 via UART. ![]() Once connected, you can write python code on the UART terminal and press Enter.To see the prompt, you need to use an UART terminal on host computer and connect to the ESP32 board via USB.Provide an interactive python prompt called REPL (Read Evaluate Print Loop) over UART (or WiFi, which we will covered in another article).Booting up the ESP32 chip then create an application that manages ESP32’s UART interface.This firmware is developed using Espressif ESP-IDF framework and is written in C. micropython firmware: to run micropython code, you need to flash a special firmware onto the ESP32 target chip.In this article, we are using ESP32 DevKit C. ESP32 board: this is a PCB board containing ESP32 chip and an UART-to-USB interface so that host computer can communicate with the target ESP32.To understand how everything works, let’s take a look at the following diagram:Īs can be seen from the diagram, there are several components when working with micropython: If you know already know how to write python code, then micropython makes it possible to run python programs on those microcontrollers. ![]() Micropython is a project aiming at running python 3 code on certain families of microcontrollers with limited resources. We will be using ESP32-DevKitC as listed in the table below QTYĪffiliate Disclosure: When you click on links in this section and make a purchase, this may result in this site earning a commission at no extra cost to you. In order to follow along with this tutorial, you will need an ESP32 development Kit.
