Arduino——PAJ7620手势识别模块

手势识别模块

---

前言

在用arduino驱动这些模块得时候，方法很简单，先去管理库中找这个库，如果有这个库，然后下载这个库，运行历程就行。

一、安装PAJ7620库

下载第二个库，然后找到

下面有你需要的历程

然后对应接线就可以了，SCL,SDA在uno上有专门的引脚，或者接到A4 A5上都可以。

二、代码

#include <Wire.h>
#include "paj7620.h"

/* 
Notice: When you want to recognize the Forward/Backward gestures, your gestures' reaction time must less than GES_ENTRY_TIME(0.8s). 
        You also can adjust the reaction time according to the actual circumstance.
*/
#define GES_REACTION_TIME		500				// You can adjust the reaction time according to the actual circumstance.
#define GES_ENTRY_TIME			800				// When you want to recognize the Forward/Backward gestures, your gestures' reaction time must less than GES_ENTRY_TIME(0.8s). 
#define GES_QUIT_TIME			1000

void setup()
{
    
    
	uint8_t error = 0;

	Serial.begin(9600);
	Serial.println("\nPAJ7620U2 TEST DEMO: Recognize 9 gestures.");

	error = paj7620Init();			// initialize Paj7620 registers
	if (error) 
	{
    
    
		Serial.print("INIT ERROR,CODE:");
		Serial.println(error);
	}
	else
	{
    
    
		Serial.println("INIT OK");
	}
	Serial.println("Please input your gestures:\n");
}
