Epp+dis learning path (1) -- Hello world!

    In the public, “ Ningzhong physics Innovation Laboratory ” Wrote a lot based on Mixly Introduction to , I feel that my ability to write code is also declining ...... Because the information technology selective examination in Zhejiang Province has already been taken phthon Programming the , So I thought if ESP32+Python+Phyphox The combination of the three （ abbreviation EPP Well ） Develop physical DIS Experimental words , That really can achieve the perfect integration of multiple courses . So we have the idea of developing elective courses based on these three , Try to finish this summer vacation , We can teach students in the club class next semester .

        Most of the previous articles are written by my own previous experience , Then these are my learning paths , Although it will be a little python, But it's still very shallow , So I learned while writing .

       ESP32 Upper python Strictly speaking, it should be called micropython, There are many software available , Let's choose a relatively simple software ——Thonny To write! .

      python It is an interpretative high-level language ...... About the introduction of language, I went to Baidu . use python Here it is ESP32 The best thing about writing programs is that they are super fast ！ Compared with Mixly About fast 100 times ！ Nonsense , Get to the point ：

One 、Thonny

  Download the software first , You can baidu , Go to the official website , In this way, we can get to the latest , Of course, you can also use what I share .

link ：https://pan.baidu.com/s/1BMrNs1Lz6HNciNFjFs7h-A?pwd=nbzx

Extraction code ：nbzx

   Install after download

A very clean and concise software . Then in order to give ESP32 Write program , Still have to give ESP32 Write support micropython The firmware of , You can use Baidu or my following ：

link ：https://pan.baidu.com/s/1S3iIFn6btyQ2L22N7345AQ?pwd=nbzx

Extraction code ：nbzx

After downloading, it's a .bin The file of

Next, let's use Thonny to ESP32 To burn in new firmware ：

Open the tool first - Set up - decoder , Pay attention to the choice above MicroPython（ESP）,Port Choose yours ESP32 Corresponding COM mouth （ Of course, you have to insert ESP32）, Then click on the bottom right corner Install......

 

Open it as follows , Again Port Is your ESP32 Corresponding COM mouth ,Firmware That's what I shared above .bin file . Then click Install .

 

about 100 Seconds later, the recording is finished . Then close and enter Thonny The main page ：

Two 、Hello world！

  Below the main page Shell There will be Python The dialog . Because it is a high-level language , It supports conversational programming , Let's say hello to new world first , stay Shell Enter print("Hello world!")

 

Then it outputs Hello world!

Be careful , At the moment ESP32 Output Hello world！ Hardware players generally don't like this way of greeting , Our way of greeting is usually to light a light ！ Here we go. ESP32 The lamp on board is on .

Enter ：

import machinepin = machine.Pin(2, machine.Pin.OUT)pin.on()

 

Then click the button with a white arrow in the middle of the green circle , Then a dialog box will come out

Ask where you want to save the program , Of course MicroPython equipment

stay File name Input in main.py, Point determination .

And then in a second , The program is uploaded , Observe ESP32 Is the light on the light on ！

    After lighting the light, you should be able to understand ESP32 On Micropython The mechanism of operation , In fact, the program we want to run is named main.py And then upload it to ESP32 Just go up ,ESP32 It will run automatically as soon as it is powered on main Program .
