Module to control an l298n motor controller on a Pi,dependencies pigpio.
npm install pigpio-l298n
$ npm install pigpio-l298n
`
用法
可以控制两个连接到L298N的电机。电机被编号为NO1和NO2.
使用模块的例子
`
const readline = require('readline');
const L298N = require('../l298n.js');
//bcm code
let l298n = new L298N(17,27,22,null,null,null);
l298n.setSpeed(l298n.NO1,20);
const rl = readline.createInterface({
input: process.stdin,
output: process.stdout
});
rl.on('line', function (input) {
if (input === 'quit()') {
rl.close();
} else if (input === 'f') {
l298n.forward(l298n.NO1);
} else if (input === 'b') {
l298n.backward(l298n.NO1)
} else if (input === 't') {
l298n.stop(l298n.NO1);
} else {
l298n.setSpeed(l298n.NO1,parseInt(input));
}
});
process.on("SIGINT", function(){
l298n.stop(l298n.NO1);
console.log('shutdown!');
process.exit(0);
});
`
设置转速
`
l298n.setSpeed(NUM(NO1\NO2), speed(0-100));
`
向前转动
`
l298n.forward(NUM(NO1\NO2));
`
向后转动
`
l298n.backward(NUM(NO1\NO2));
`
停止转动
`
l298n.stop(NUM(NO1\NO2));
