成员枚举类型说明

◆ ErrorCode

enum emakefun::GestureRecognizer::ErrorCode : uint32_t

错误码

枚举值
kOK	0：成功
kI2cDataTooLongToFitInTransmitBuffer	1：I2C数据太长，无法装入传输缓冲区
kI2cReceivedNackOnTransmitOfAddress	2：在I2C发送地址时收到NACK
kI2cReceivedNackOnTransmitOfData	3：在I2C发送数据时收到NACK
kI2cOtherError	4：其他I2C错误
kI2cTimeout	5：I2C通讯超时
kInvalidParameter	6：参数错误
kUnknownError	7: 未知错误

◆ Gesture

enum emakefun::GestureRecognizer::Gesture : uint8_t

手势类型

枚举值
kGestureNone	0x00: 无手势动作
kGestureRightSwipe	0x01: 右移动作
kGestureLeftSwipe	0x02: 左移动作
kGestureBackwardSwipe	0x03: 后移动作
kGestureForwardSwipe	0x04: 前移动作
kGestureUpward	0x05: 上拉动作
kGestureDownward	0x06: 下压动作
kGestureExited	0x07: 离开感应区
kGestureHover	0x08: 悬停

构造及析构函数说明

◆ GestureRecognizer()

emakefun::GestureRecognizer::GestureRecognizer	(	TwoWire &	wire = `Wire`,
		const uint8_t	i2c_address = `kDefaultI2cAddress`
	)

explicit

构造函数

参数

[in]	wire	TwoWire对象，默认为Arduino Wire
[in]	i2c_address	手势识别传感器I2C地址，默认值为0x39

成员函数说明

◆ GetGesture()

GestureRecognizer::Gesture emakefun::GestureRecognizer::GetGesture ( )

获取识别到的手势

返回: 手势类型，参考枚举: GestureRecognizer::Gesture

类成员变量说明

◆ kDefaultI2cAddress

constexpr uint8_t emakefun::GestureRecognizer::kDefaultI2cAddress = 0x39

staticconstexpr

手势识别传感器默认I2C地址

0x39: 默认I2C地址
