M5Core2 Arduino Library
**问题描述：** 使用 M5Core2 录音存储 pcm 文件，然后从 pcm 文件读数据，使用 I2S 可以播放（音量较低，听着也有杂音，但是能正常听清内容）。但是从电脑打开该 pcm 文件，不能正常播放（进而导致 ASR 服务不能正常进行识别）。 怀疑过电脑打开 pcm 设置不对，所以尝试了电脑能正常播放的 WAV(PCM+header)，M5Core2 也能正常播放该 WAV 文件。也尝试了电脑换不同的参数打开（虽然很确定录音参数，以防万一^-^!）,包括各种采样率，位宽，大小端，声道数 等，也不能正常播放。同时，换了各种采样率/I2S参数进行录音，并不奏效。基本断定是获取的 pcm 文件本身就有问题。 使用该 repo 提供的录音样例 https://github.com/m5stack/M5Core2/blob/master/examples/Basics/record/record.ino ，存储为pcm文件，也有该问题。 所以感觉是...
Hi, I'm trying to play wav file from SD card on my Core 2, I find the M5Unified library seems to have the solution however M5Core2 Library does not. Wondering...
deleted line SetPeripheralsPower(true) within AXP192::begin() code which causes PowerOff on M5Core2 hardware powered externally via 5V Bus w/o USB cable connected. The crash is caused by setting EXTEN to 1...

A bad commit has been merged on master branch :eyes:
AppWifi work only. - Fixed number of lines per page - Added new color for strong network signals (blue).
The TFT_eSPI_Button compatibility mode was half-baked and apparently untested: `TFT_eSPI_Button::justPressed()` and `TFT_eSPI_Button::justReleaed()` always returned true :facepalm: With this patch, TFT_eSPI_Button does not use the `::contains()` and `::isPressed()` methods from the...
The VL bit in the seconds register records a voltage low event that could invalidate the date and time readings. It's already in M5 Unified, but many of us are...
This allows you to draw text such that characters that would be drawn cannot be seen since they are offscreen (say, -100) The functionality is toggled on with `#define FORCE_TEXT_ON_SCREEN`
### Describe the bug I want to use M5Core2 at Ethernet network (not WIFI network). I try to use Ethernet and ESP_Mail_Client library to send e-mail but it failed. ###...
