this post here的答案提供了一个查询来查找邻接列表中节点的所有祖先。
现在,如何使用类似查询查找节点的所有后代?我试过了:
#2014 Commands out of sync. You can't run this command now
我只是交换senderid和receiverid,但它给了我import gpio from 'gpio';
import proximity from './proximity';
const gpio4 = gpio.export(4, {
direction: 'in',
});
// bind to the "change" event
gpio4.on('change', (val) => {
// value will report either 1 or 0 (number) when the value changes
if (val === 1) {
console.log('checking proximity');
proximity.getDistance();
}
});
。
有什么想法吗?
