ESP32 C3

Overview

Open source address: https://gitee.com/st7_1a/esp32-c3.git

Function introduction: (Due to shooting issues, the screen image may not be very good)

Main interface: After powering on, connect to the mobile hotspot. After a few seconds, the real-time time will be displayed in the upper left corner.

Interface 2: Displays real-time weather conditions. This part is referenced from LCSC's Practical App.
It will reconnect to the mobile hotspot every once in a while.

Interface 3: Functional interface
1. The color palette in the upper left corner controls the RGB lights under the board. Select any color, then long-press the blank part in the middle of the color palette to jump to the color palette from dark to light... and so on. After trying a few times, it will jump back to the initial color palette. The avocado switch controls the RGB lights to turn on and off.
2. The button in the middle on the right controls the buzzer. There are two modes: a short press makes a sound, "the middle Buzzer will change to Short".
A long press makes intermittent sounds, stopping after 5 seconds, "the middle Buzzer will change to Long".
3. The two sliders in the lower right corner control the screen brightness and volume respectively.
4. The curve in the lower left corner displays the battery level in real time.

The board also has a gyroscope and a temperature and humidity sensor, the same model as those on the LCSC Practical Edition, which are already soldered and can be used directly with the official code.

Initialization of string pointers
If you want to initialize a string, there are two ways to write it: 1: char *p = "hello"; 2: char *p; p = "hello"; Are these two ways wrong? Are there any differences? Tan Haoqiang C Programming p238

The task scheduling cycle of DM8168 is problematic. The simplest task will also intermittently have a scheduling cycle of about 335ms.
After the DM8168 system is started, only one main task is created, and only the following simple loop is performed in it, which is to continuously print the current execution time interval. Statistics
