## 描述
|
||
|
||
|
||
**M5StickC PLUS** 是M5StickC的大屏幕版本，主控采用ESP32-PICO-D4模组，具备蓝牙4.2与WIFI功能，小巧的机身内部集成了丰富的硬件资源，如红外、RTC、麦克风、LED、IMU、按键、蜂鸣器、PMU等，在保留原有M5StickC功能的基础上加入了无源蜂鸣器，同时屏幕尺寸升级到1.14寸、135*240分辨率的TFT屏幕，相较之前的0.96寸屏幕增加18.7%的显示面积，电池容量达到120mAh，接口同样支持HAT与Unit系列产品.
|
||
|
||
|
||
**开关机操作：**
|
||
|
||
* 开机：按复位按键，持续至少 2 秒
|
||
|
||
* 关机：按复位按键，持续至少 6 秒
|
||
|
||
**注意：**
|
||
|
||
* M5StickC Plus支持的波特率: 1200 ~115200, 250K, 500K, 750K, 1500K
|
||
|
||
* G36/G25共用同一个端口，当使用其中一个引脚时要将另外一个引脚设置为浮空输入
|
||
* 比如要使用G36引脚作为ADC输入，则配置G25引脚为浮空状态
|

```arduino
|
||
setup()
|
||
{
|
||
M5.begin();
|
||
pinMode(36, INPUT);
|
||
gpio_pulldown_dis(GPIO_NUM_25);
|
||
gpio_pullup_dis(GPIO_NUM_25);
|
||
}
