如果把
if(Serial.available()>0)
{
val = Serial.read();
switch(val)
{
case 'q': //測距離
for(int i = 0; i < 3; i++)
Serial.write(packet); //send packet to phone
break;
case 'f': // car forward
forward(0, 255);
break;
case 'd': // car backward
backward(0, 255);
break;
case 'l': // car turn left
left(0, 255);
break;
case 'r': // car turn right
right(0, 255);
break;
case 's': // car stop
motorstop(0, 0);
break;
}
}
}
會出現call of overladed write(byte [3])' is ambiguous 調用write（byte [3]）'是不明確的
是不應該write嗎?作者: leo0983405269 時間: 2017-10-16 18:04 本帖最後由 leo0983405269 於 2017-10-16 18:07 編輯
