const data = [ 97, 98, 99, 100 ];
let path = "";
function handle(value:any){
console.log("handle::",value);
}
function autoWrite(){
setInterval(function () {
_Port.write(path,data);
}, 1000);
}
_Port.list().then((v:any)=>{
const size = v.length;
if (size<1){
return ;
}
const option = v[size-1];
console.log("option:",option);
path = option.path;
_Port.createPort({ path: path, baudRate: 115200, autoOpen: true },handle);
if (path =="")return;
autoWrite();
// _Port.close(path);
});
