【ESP32-Korvo Review】 04 Development Environment Construction [Copy link]

 

 

The previous review article described a smart atmosphere light example based on the Blinker component written in the Arduino environment . Unfortunately, it can only be used for basic program development of the ESP32-WROVER module, and this development board is a voice application, which does not seem to be supported by Arduino . I can only honestly install the official development environment of Espressif.

Log in to Espressif's official website and find the development board page: Development Board Overview | Espressif Technology (espressif.com)

Click "User Guide" to view the user instructions for the development board:

The user guide mainly includes an introduction to the development board, environment construction, sample codes, etc.

The user guide explains how to use the default firmware for the development board, which is a simple voice control program that can control the on/off and color of the light.

To develop ESP32-Korvo voice function programs, you need to install ESP-IDF and ESP-Skainet . ESP-IDF is the basic tool for developing ESP32 , while ESP-Skainet is a voice assistant tool specially developed by Espressif.

1. Install ESP-IDF

As we can see, to use ESP-IDF, you need to install git and python . There are two ways to install them: one-click installation through the official installation assistant or download and install the three software separately. Since I have already installed python when I installed the Arduino development environment , I chose the second installation method and downloaded and installed them separately.

Download Git Windows version and install:

Download the ESP-IDF installation package. The user guide recommends using version V3.3.1 . OK , let’s use this version.

Download address:

I refreshed the git page many times before entering it. The download was also very slow, only a few KB in speed, and often became 0KB . Git is becoming less and less friendly to Chinese users. I decisively gave up this method and downloaded the esp-idf-tools tool directly from the official website : https://dl.espressif.com/dl/esp-idf-tools-setup-2.3.exe

After downloading, run esp-idf-tools . Since git and python are already installed on your computer , the installer will automatically identify the installation path. Just click Next to come to the ESP-IDF version selection interface.

The development board user guide recommends using version V3.3.1 , so I chose version V3.3 for installation here, and then entered a long download wait. The speed is really unparalleled ... I was in tears ... I strongly recommend that Espressif put the relevant information and tool software on a local server or on China's gitee .

After waiting for more than an hour, a failure message still popped up.

I'm speechless. What's wrong? It's my network problem, but my broadband is 100M . The speed of browsing other web pages and downloading resources is very fast.

Ok, let's skip to the next step.

(II) Install ESP-Skainet

Go to the ESP-Skainet page from the User Guide:

Judging from the introduction on the website, ESP-Skainet's offline function is still very powerful. It can recognize up to 100 offline speech words, and also integrates echo cancellation AEC (Acoustic Echo Cancellation), automatic gain adjustment AGC (automatic_gain_control), noise suppression NS (Noise Suppression), voice activity detection VAD (Voice Activity Detection) and microphone array algorithm (Mic Array Speech Enhancement).

Use the git command to clone ESP-Skainet locally:

git clone --recursive

The result is another long wait...

Continue to the next step

(III) Install the Flash download tool

Go to the official website of Espressif to download a PC -side Flash download tool, download link:

https://www.espressif.com/zh-hans/support/download/other-tools

If you have a useful tool, you should definitely use it. It’s so time-consuming to type in commands, haha.

At the end of the article: When I finished writing this review report, ESP-IDF and ESP-Skainet had not been successfully downloaded. How can I develop application code later? I was in tears and decided to go to bed first.

Thanks for sharing, the process is very clear! Like it!

Have you downloaded it successfully? Can you ask @cruelfox @数码小叶 @yangjiaxu where they downloaded it, or if they have downloaded it, please send it to you.

Not yet. I read the posts of several other review partners and they also downloaded it through git. I can only go back and try again in the evening. Oh, I am speechless. As a domestic chip company, Espressif has actually uploaded most of its resources to the Internet. It is too unfriendly. Moreover, a lot of the information is also in English.

cruelfox

I downloaded esp-skainet from git. All other tools were downloaded directly from the Espressif website.

I uploaded an esp-skainet package file to EE's download center, and you can download it and use it.

If you want to use the idf.py tool and some submodules, you must clone it completely with the parameter --recursive. It will take more than ten hours on a slow network and tens of minutes on a fast network. A complete clone of idf+skainet is 2G in size. If you use your Flash download tool to download the program to 32, you may not need a complete clone. I haven't tried it.

Well, I also discovered a problem. During the day, Github's webpage often cannot be opened. Even changing the hosts file does not work. On the contrary, browsing GitHub is slightly normal after 10 o'clock in the evening. I don't know if it is because it is daytime in the United States. Haha, so embarrassing.

Well, thank you. I'll try it again after get off work tonight.

You need to change the IP in the hosts file yourself, don't copy it from the Internet. Different operators have different effects. I don't understand why GitHub's IP changes every once in a while.

Well, I just relocated GitHub's IP address in ipaddress and filled in the hosts file instead of using the one on the website. But the effect was not good and there was no improvement.
