This article is about what Euglena is. Xiaobian thinks it is quite practical, so share it with everyone for reference. Let's follow Xiaobian and have a look.

Euglena is an Iot (international of things) platform with a simple look and a strong heart. You can develop Euglena in C or Python. Python is recommended if you are a Windows or Mac OS user.

A brief introduction to Euglena. Euglena is based on the ESP 32S IoT module (click to view module details), which integrates dual-core 240 MHz processor, WIFI, Bluetooth 4.2 and rich peripheral resources. Euglena supports mirco SD extension, using TI's lithium battery fast charging technology. Euglena is a fully open source hardware project hosted on github:

Limited to hardware resources, Euglena runs micropython, whose syntax is consistent with Python 3. Unlike Python 3, most Python 3 libraries require alternate versions or are unavailable in micropython. Some Python 3 built-in functions are also different or unavailable on micropython.

If you don't have Python basics, I suggest you buy a Python 3 study book. If you have Python basics, just pay attention to micropython features.

Euglena supports serial REPL (real-time interactive interface) and telnet. The Telnet account is micro and the password is python.

It is recommended to log into Euglena using SercureCRT HyperTerminal software.

No account or password is required to log in to Euglena via serial port. Serial port parameters are shown in the figure below, note that the baud rate is 115200.

The serial port number, which can be viewed in the Device Manager.

After logging in via serial port, Euglena will automatically restart. If you don't want Euglena to run the default program, short the SAFE (pin on the back of the USB socket) on the board and Euglena will go into "safe mode."

Wait for the system startup to complete. After startup, the interface is as follows:

Switch the input method to English. Enter print("hello world") and press Enter to simply state. The effects are as follows:

You need to connect to Euglena's WiFi hotspot before you can log in to Euglena using Telnet. Euglena's WIFI name is in the format GM-XXXX and the password is GeekModels. The telnet settings for SercureCRT are shown in the figure.

Alternatively, after installing the firefox extension firebbs, type telnet://192.168.4.1 in the address bar.

Log in as micro, password is python. SercureCRT login as shown below

Screenshot after login in Firefox

Log in, you can enter the language and press enter to execute.

For example, change Euglena's blinking color

import pycom

pycom.beatcolor(0x005000)

Enjoy ：-）
