3 工作原理
这是一个单刀双掷继电器,线圈电压为直流5V,触点电流可达10A,适合驱动直流或交流大功率负载。NO为常开触点,NC为常闭触点,COM为公共触点。当向S引脚施加高电平,继电器线圈导通,此时NO触点断开,NC触点闭合。
4 硬件连接
4.1 连接NanoPi NEO/NanoPi NEO Air
NanoPi M1和NanoPi NEO以及NanoPi NEO Air的前24Pin引脚定义是一模一样的,所以它们操作Matrix配件的步骤是一样的,并且使用同一份代码。
参考下图连接模块:
Matrix-Relay_nanopi_NEO
连接说明:
Matrix-Relay | NanoPi NEO |
S | Pin7 |
V | Pin4 |
G | Pin6 |
4.2 连接NanoPi M1
连接说明:
Matrix-Relay | NanoPi M1 |
S | Pin7 |
V | Pin4 |
G | Pin6 |
4.3 连接NanoPi 2
连接说明:
Matrix-Relay | NanoPi 2 |
S | Pin7 |
V | Pin4 |
G | Pin6 |
4.4 连接NanoPi M2 / NanoPi 2 Fire
NanoPi M2和NanoPi 2 Fire的40 Pin引脚定义是一模一样的,所以它们操作Matrix配件的步骤是一样的,这里仅以NanoPi M2为例。
参考下图连接模块:
连接说明:
Matrix-Relay | NanoPi M2 |
S | Pin7 |
V | Pin4 |
G | Pin6 |
4.5 连接NanoPi M3
参考下图连接模块:
Matrix-Relay_nanopi_m3
连接说明:
Matrix-Relay | NanoPi M3 |
S | Pin7 |
V | Pin4 |
G | Pin6 |
4.6 连接NanoPC-T2/NanoPC-T3
由于NanoPC-T2跟NanoPC-T3的引脚是一样的,所以连接方式是一样的,这里仅以T2为例,参考下图连接模块:
Matrix-Relay_NanoPC-T2
连接说明:
Matrix-Relay | NanoPC-T2 |
S | Pin15 |
V | Pin29 |
G | Pin30 |
5 编译运行测试程序
启动开发板并运行Debian系统,进入系统后克隆Matrix代码仓库:
$ apt-get update && apt-get install git $ git clone https://github.com/friendlyarm/matrix.git
克隆完成后会得到一个名为matrix的目录。
编译并安装Matrix:
$ cd matrix $ make && make install
运行测试程序:
$ matrix-gpio_out
注意:此模块并不支持热插拔,启动系统前需要确保硬件连接正确。
运行效果如下:
1: gpio status change 2: gpio status change 3: gpio status change 4: gpio status change 5: gpio status change
6 代码说明
所有的开发板都共用一套Matrix代码,本模块的测试示例代码为matrix-gpio_out,内容如下:
int main(int argc, char ** argv) { int pin = GPIO_PIN(7); int i, value, board; int ret = -1; if ((board = boardInit()) < 0) { printf("Fail to init board\n"); return -1; } if (board == BOARD_NANOPI_T2) pin = GPIO_PIN(15); if (argc == 2) pin = GPIO_PIN(atoi(argv[1])); if ((ret = exportGPIOPin(pin)) == -1) { printf("exportGPIOPin(%d) failed\n", pin); } if ((ret = setGPIODirection(pin, GPIO_OUT)) == -1) { printf("setGPIODirection(%d) failed\n", pin); } for (i = 0; i < STATUS_CHANGE_TIMES; i++) { if (i % 2) { value = GPIO_HIGH; } else { value = GPIO_LOW; } if ((ret = setGPIOValue(pin, value)) > 0) { printf("%d: GPIO_PIN(%d) value is %d\n", i+1, pin, value); } else { printf("setGPIOValue(%d) failed\n", pin); } sleep(1); } unexportGPIOPin(pin); return 0; }
