1.连线 我使用的是Arduino(UNO)开发板和LCD1602带拓展板I2C。具体连线比较简单。 GND --- 地线 VCC --- 电源5V SDA --- I2C 数据线 SCL --- I2C 时钟线 2.安装库 arduinoIDE里面有专门为lcd1602编写的库,打开项目->加载库->搜索LiquidCrystal_I2C 3.查找串口地址 首先需要知道LCD的串口地址,之后会用到 ...
MegaPRO(嵌入式)2560CH340G / ATmega2560-通过microUSB电缆连接到计算机(几乎适用于所有Android智能手机)。 您可以通过 p1:aduino上传报错:avrdude: ser_open(): can't open device "\\.\COM3":系统找不到指定的文件 这里是指arduino端口的驱动,正常下载IDE之后就已经安装好了,我是在使用arduinouno开发板时一切...

I2C总线的Arduino库函数 I2C即Inter-Integrated Circuit串行总线的缩写,是PHILIPS公司推出的芯片间串行传输总线。它以1根串行数据线(SDA)和1根串行时钟线(SCL)实现了双工的同步数据传输。具有接口线少,控制方式简化,器件封装形式小,通信速率较高等优点。在主

A better I2C master library, originally by Wayne Truchsess. Seehttp://dsscircuits.com/index.php/articles/66-arduino-i2c-master-library On most Arduino boards, SDA (data line) is on analog input pin 4, and SCL (clock line) is on analog input pin 5. On the Arduino Mega, SDA is digita...
The problem turned out to be due to relatively long cables that I used for SDA and SCL pins. Apparently 2 jumper cables are too much for STM32 i2c communication. The weird thing is it has no effect whatsoever on an Arduino UNO.
It's just like our popular PWM/Servo Breakout but now Arduino-ready and works with any Arduino that uses shields: Uno, Leo, Mega, ADK, its all good. Play video: Servo party - Adafruit 16-Channel 12-bit PWM/Servo Shield -- I2C interface When we saw this chip, we quickly realized ...
