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...
实现巴法云平台对ESP8266的OTA指令升级,基于前面两个实验。 2. 实验准备 本次需要做三个实验,分别是TCP点灯实验,MQTT发送温湿度和OTA指令升级,准备工作包括硬件💡💡💡和软件💻💻💻两部分。 2.1 硬件 你要实现巴法云的三个实验,你需要准备以下材料✨✨✨ ...

delay(ms) This method tells the program to wait for a given number of milliseconds before executing the next instruction. In practice, this means that in the following lines of code: digitalWrite(13, HIGH); delay(1000); digitalWrite(13, LOW); there will be a delay of one full second bet...

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...
