/ / the loop routine runs over and over again forever: void loop() { digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level) delay(1000); digitalWrite(led, LOW); delay(1000); // wait for a second // turn the LED off by making the voltage LOW // wait for a...

One workaround is to wait for the IR receiver to be idle before you send the Neopixel data with if (IrReceiver.isIdle()) { strip.show();}. This prevents at least breaking a running IR transmission and -depending of the update rate of the Neopixel- may work quite well. There are ...

If you do this, the firmware will wait UI_DELAYPERCHAR microseconds after each byte send. The faster method is to have a RW pin, so the firmware can ask the display if it is ready for the next command.#if UI_DISPLAY_TYPE==3 // I2C Pin configuration #define UI_DISPLAY_RS_PIN _BV...
第5章Arduino的基本函数 目录1 目录 5 目录9 5.1数字I/O 5.1.1pinMode(pin,mode)pinMode函数用于配置引脚为输入或输出模式，它是一个无返回值函数，一般放在setup里，先设置再使用。pinMode函数有两个参数——pin和mode。pin参数表示要配置的引脚，以ArduinoUno为例，它的范围是数字引脚0～13，也可以把模拟...
