WiFi and Bluetooth are supported as standard and it includes an on board 16MB Flash and 8MB PSRAM, USB TYPE-C interface for charging, downloading of programs and serial communication, a 2.0-inch integrated capacitive touch screen, and a built-in vibration motor. 20 | 21 | M5Core2 also features a built-in RTC module which can provide accurate timing. The power supply is managed by an AXP192 power management chip, which can effectively control the power consumption of the base and a built-in green LED power indicator helps to notify the user of battery level. The battery capacity has been upgraded to 390mAh, which can power the core for much longer than the previous model. 22 | 23 | The M5Core2 retains the SD card slot and speakers. However, in order to ensure higher quality sound output, the I2S digital audio interface power amplifier chip is used to effectively prevent signal distortion. There are independent power and reset buttons on the left side and bottom of the base. 24 | 25 | The 3 icons on the front of the screen are capacitive buttons which are programmable. There is a small expansion board on the back of the base with a 6-axis IMU sensor and microphone. 26 | 27 | ## M5Core2 M-BUS Schematic diagram 28 | 29 | 30 | 31 | ## More Information 32 | 33 | **UIFlow Quick Start**: [Click Here](https://docs.m5stack.com/en/quick_start/core2/uiflow) 34 | 35 | **MicroPython API**: [Click Here](https://docs.m5stack.com/en/quick_start/core2/mpy) 36 | 37 | **Arduino IDE Development**: [Click Here](https://docs.m5stack.com/en/quick_start/core2/arduino) 38 | 39 | **M5Core2 Arduino API**: [Click Here](https://docs.m5stack.com/en/api/core2/axp192_core2) 40 | 41 | **PinMap**: [Click Here](https://docs.m5stack.com/en/core/core2) 42 | -------------------------------------------------------------------------------- /README_cn.md: -------------------------------------------------------------------------------- 1 | # M5Core2 Library 2 | 3 | [![Arduino Compile](https://github.com/m5stack/M5Core2/actions/workflows/arduino-action-compile.yml/badge.svg)](https://github.com/m5stack/M5Core2/actions/workflows/arduino-action-compile.yml) 4 | [![Arduino Lint](https://github.com/m5stack/M5Core2/actions/workflows/Arduino-Lint-Check.yml/badge.svg)](https://github.com/m5stack/M5Core2/actions/workflows/Arduino-Lint-Check.yml) 5 | [![Clang Format](https://github.com/m5stack/M5Core2/actions/workflows/clang-format-check.yml/badge.svg)](https://github.com/m5stack/M5Core2/actions/workflows/clang-format-check.yml) 6 | 7 | 中文 | [English](README_cn.md) 8 | 9 | M5Core2_P1 10 | 11 | * **如果查看 M5Core2 的详细介绍文档，[点击这里](https://docs.m5stack.com/zh_CN/core/core2)** 12 | 13 | * **如果想要购买 M5Core2 的话，[点击这里](https://item.taobao.com/item.htm?spm=a1z10.5-c-s.w4002-22404213529.31.5ada1d91KUL15v&id=625561056791)** 14 | 15 | ## 描述 16 | 17 | **M5Core2** 是M5Stack开发套件系列中第二代主机，在原有一代主机基础上对功能进一步加强，硬件功能更加齐全。主控ESP32型号为D0WDQ6-V3，具有两个可以单独控制的 Xtensa® 32-bit LX6 处理器，主频高达240Mhz，支持WiFi与蓝牙功能，板载16MB Flash与8MB PSRAM，可通过TYPE-C接口下载程序，强劲的配置满足复杂应用的资源开销。正面搭载一块2.0寸一体化电容式触摸屏，为用户带来更流畅的人机交互体验。机身内置震动马达，可提供触觉回馈和震动提醒功能。内建的RTC模块可提供精准计时功能。电源部分搭载AXP192电源管理芯片可有效控制机身功耗，内置绿色电源指示灯，配备390mAh电池，续航时间更持久。同时机身内配备了SD卡槽与扬声器，为了保证获得更高质量的声音效果，采用I2S数字音频接口的功放芯片，能有效防止信号失真。在机身的左侧和底部配有独立的电源按键与重启(RST)按键，屏幕正面的3个圆点属于触摸屏的一部分，可通过编写程序设置热区映射为3个虚拟按键。机身背部有一块扩展小板，板上带有6轴IMU传感器与麦克风。 18 | 19 | ## M5Core2 M-BUS示意图 20 | 21 | 22 | 23 | 24 | ## 更多信息 25 | 26 | **UIFlow 快速上手**: [点击这里](https://docs.m5stack.com/zh_CN/quick_start/core2/uiflow) 27 | 28 | **MicroPython API**: [点击这里](https://docs.m5stack.com/zh_CN/quick_start/core2/mpy) 29 | 30 | **Arduino IDE 环境搭建**: [点击这里](https://docs.m5stack.com/zh_CN/quick_start/core2/arduino) 31 | 32 | **M5Core2 Arduino API**: [点击这里](https://docs.m5stack.com/zh_CN/api/core2/axp192_core2) 33 | 34 | **引脚地图**: [点击这里](https://docs.m5stack.com/zh_CN/core/core2) 35 | -------------------------------------------------------------------------------- /examples/Advanced/Display/Display_Unicode/Display_Unicode.ino: -------------------------------------------------------------------------------- 1 | /* 2 | ******************************************************************************* 3 | * Copyright (c) 2021 by M5Stack 4 | * Equipped with M5Core2 sample source code 5 | * 配套 M5Core2 示例源代码 6 | * Visit for more information: https://docs.m5stack.com/en/core/core2 7 | * 获取更多资料请访问: https://docs.m5stack.com/zh_CN/core/core2 8 | * 9 | * Describe: Display_Unicode.
