其中最为明显的一个就是,舵机库和LCD库的冲突,前者是默认的servo库,后者是i2c的LCD库。对于输出统计数字,我一开始认为只要在每个循环后面都刷新一次就好了,反正只要计数器准确就不会有问题。事实上,这样做会因为串口通讯影响到舵机库的输出而让舵机一直颤抖。我偷懒用了i2c的LCD驱动芯片,想减少接线的复杂度,于是在...
见下文,我开始了串行通信、I2C 通信和 LCD 操作。 此外,我通过循环将 LED 引脚配置为输出。 void setup(){Serial.begin(9600);Wire.begin();lcd.init();lcd.backlight();for(byte i =2; i <=4; i++){pinMode(i, OUTPUT);}if(!apds.begin()){Serial.println("Falha ao inicializar o dispositivo...
