if (real_press) { count_presses++; Serial.println(count_presses); } delay(1); // delay in between reads for stability } 将其上传到Arduino Uno,然后启动串行监视器。 此代码所做的全部就是计数按钮的按下次数并将其打印在串行通讯线上。代码是不言自明的。
(i.e. shift the value one bit to the right), yielding an address between 0 and 127. However the addresses from 0 to 7 are not used because are reserved so the first address that can be used is 8. Please note that a pull-up resistor is needed when connecting SDA/SCL pins. Please...
If you use the Insight SIP4520 or the RAKwireless RAK4630/4631 modules the connections between the chips are fixed. In this case you do not need the hwConfig structure and can instead use simplified initialzation functions as shown below. ...
