Move or copy the relevant core and device drivers into your project tree or library subfolder (For Arduino, this means the/Arduino/I2Cdevand/Arduino/MPU6050folders, for example) Rescan libraries or restart your IDE if necessary For both usage and development, I've found that it's best to ...
Arduino Software I2C User Guide The standard I2C library for the Arduino is the Wire library. While this library is sufficient most of the time, there are situations when it cannot be used: the I2C pins A4/A5 (or SDA/SCL) are in use already for other purposes same I2C addresses devices...
Arduino I2C master library 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中使用I2C通信可直接调用Wire.h库, 这个库允许Arduino链接其他I2C设备, 链接线有两条, 分别是SDA(数据行)和SCI(时钟线). 各型号Arduino的I2C对应引脚: Arduino Board:I2C / TWI pins Arduino Uno/Ethernet:A4 (SDA), A5 (SCL) Arduino Mega2560:20 (SDA), 21 (SCL) Arduino Leonardo:2 (SDA), 3...

arduino的wire.cpp文件 参考链接 IIC总线通讯介绍 i2c总线最多可以挂127个外设,由IIC地址决定,一个字节即8位地址,减去1位广播地址,是7位地址,2^7=128,但是地址0x00不用,那就是127个地址, 所以理论上可以挂127个外部设备。

I've put together a simple library for I2C LCD displays using the HD44780 driver to perform most of the basic tasks that might be useful for simple projects. I'm posting mainly because these displays are frequently used in small embedded projects and hopefully this can be of some help to ...
