![]() Set the correct parameters for flashing the MicroPython firmware to an ESP32 microcontroller. Make sure that “Erase flash before installing” is checked, then click “Install”. Select your device’s port again, and browse for the MicroPython firmware that you downloaded earlier for the “Firmware” field. Set the interpreter and the port.Īfter setting the interpreter and the port, click on the button that says “Open the dialog for installing or upgrading Under the “Which interpreter or device should Thonny use for running your code?” label, select “MicroPython (ESP32)”. Next navigate to “Run > Select Interpreter”. If you are not familiar with how to to do this, you should check our guide on the subject: How To Find Your Device’s Port. Now would be a good time to find out which port your device is on. Plug your ESP32 NodeMCU into your computer using a microUSB cable and launch Thonny. Download the latest MicroPython firmware for 'GENERIC' ESP32 microcontrollers with ESP-IDF v3.x. Take note of its location in your filesystem after downloading. The latest firmware should be at the very top. If the process fails, try running the same command again with elevated permissions (sudo).įrom the Micropython website, download the latest stable binary (.bin) file for ESP32 microcontrollers under the “Firmware with ESP-IDF v3.x” marked as “GENERIC”. Open a terminal and enter pip install thonny. On Windows and MacOSX I recommend installing Thonny through the download links on its website.ĭownload the Thonny installer from and run it. If you are using Linux, I recommend installing Thonny using pip. Thonny is a Python IDE that keeps the process of programming a microcontroller simple, which is great for beginners.Īfter Thonny is installed, we will go over getting Thonny setup for an ESP32 NodeMCU, flashing the MicroPython firmware, and writing a simple program for the ESP32 device using MicroPython. Through my journey, I found that the most streamlined and simple way of programming a microcontroller with MicroPython is through a program called Thonny. In the process of learning MicroPython for myself, I have used many different setups for programming microcontrollers. ![]() ![]() However we can use any variables in our conditions.Computer running Windows, Linux, or MacOSX In the above examples, we have used the boolean variables in place of conditions. Python if example without boolean variables The output of this code is none, it does not print anything because the outcome of condition is ‘false’. Lets take another example to understand this: flag = False If the outcome of condition is true then the statements inside body of ‘if’ executes, however if the outcome of condition is false then the statements inside ‘if’ are skipped. The output of the condition would either be true or false. The important point to note here is that even if we do not compare the value of flag with the ‘True’ and simply put ‘flag’ in place of condition, the code would run just fine so the better way to write the above code would be: flag = Trueīy seeing this we can understand how if statement works. In the above example we are checking the value of flag variable and if the value is True then we are executing few print statements. Python – If statement Example flag = True The syntax of if statement in Python is pretty simple. However in this guide, we will only cover the if statements, other control statements are covered in separate tutorials. There are other control flow statements available in Python such as if.else, if.elif.else, In this guide, we will learn how to use if statements in Python programming with the help of examples. For example, you want to print a message on the screen only when a condition is true then you can use if statement to accomplish this in programming. If statements are control flow statements which helps us to run a particular code only when a certain condition is satisfied.
