1 NanoPi门铃系统

1.1 NanoPi门铃系统介绍

门铃系统
  • 使用Matrix Starter Kit套件的蜂鸣器、LED、声音传感器做一个门铃系统,当按键按下时,蜂鸣器会响起来,以及LED会闪烁;当声音传感器识别到声音时,蜂鸣器也会响起来。
  • 如果需要更好的效果,可以发挥自己的想象力,按键在按下来的时候,蜂鸣器随机播放一首音乐。


1.2 Matrix配件

  • 这里需要使用到Matrix的配件为LED、声音传感器、无源蜂鸣器,均可参考以下链接了解Matrix配件的使用:
NanoPi门铃系统 NanoPi
Matrix-LED [1]
Matrix-Sound Sensor [2]
Matrix-Buzzer [3]
Matrix-Button [4]


1.3 下载Matrix源码

Matrix配件相关的代码是完全开源的,统一由一个仓库进行管理:git://github.com/friendlyarm/matrix.git
该仓库里不同的分支代表着Matrix配件所支持的不同开发板。

  • nanopi分支包含了Matrix对NanoPi的支持;
  • tiny4412分支包含了Matrix对Tiny4412的支持;
  • raspberrypi分支包含了Matrix对RaspberryPi的支持;


1.4 连接使用

NanoPi门铃系统 NanoPi
Matrix-LED PIN12
Matrix - Sound Sensor PIN7
Matrix - Sound Sensor PIN22
Matrix - Sound Sensor PIN11


1.5 编译程序及使用

进入Matrix代码仓库,切换到nanopi分支

$ cd matrix
$ git checkout nanopi

编译Matrix配件代码

$ make CROSS_COMPILE=arm-linux- clean
$ make CROSS_COMPILE=arm-linux-
$ make CROSS_COMPILE=arm-linux- install

注意:请确保你的主机PC当前使用的交叉编译器为NanoPi-Debian配套的arm-linux-gcc-4.4.3。
编译出来的库文件位于install/lib目录下,而测试程序则位于install/usr/bin目录下,模块Matrix-doorbell对应的测试程序为matrix-doorbell。
拷贝库文件和测试程序到NanoPi的文件系统上

$ cp install/usr/bin/* nanopi_rootfs/usr/bin/
$ cp install/lib/* nanopi_rootfs/lib/ -d

然后启动NanoPi,在Debian的shell终端中执行如下命令运行模块Matrixdoorbell的测试程序

$ matrix-doorbell

int devFD = -1;
 
int pwm_HZ = 1000;
int pwm_duty = 500;
 
int BUZZERpin = PWM_PIN1;
int LEDpin = GPIO_PIN3;
 
int stop = 0;
void Stop(int signo) {
	stop = 1;
}
 
int doorbell_init() {
	//sensor init
	if ((devFD = sensorInit(sensor_dev, ARRAY_SIZE(sensor_dev))) == -1) {
	        printf("Fail to init sensor sound\n");
	        return -1;
	}
 
	//LED init
	if ((exportGPIOPin(LEDpin)) == -1) {   
	        printf("exportGPIOPin(%d) failed\n", LEDpin);
		return -1;
	}
	if ((setGPIODirection(LEDpin, GPIO_OUT)) == -1) {
        	printf("setGPIODirection(%d) failed\n", LEDpin);

	}
	if(PWMStop(BUZZERpin) == -1) {
		printf("Fail to stop PWM\n");
		return -1;
	}
	return 0;
}
 
int main(int argc, char ** argv) {
	int sensor_state;
	char value[ARRAY_SIZE(sensor_dev)];
	doorbell_init();
	signal(SIGINT, Stop);
	printf("you can press ctrl+c to stop\n");
	while(!stop) {

2.1 温室报警系统介绍

温室报警系统
