This KBA provides a minimal code example with Arduino Uno board for the TLI493D-W2BW 3D magnetic sensor with the in silicon A0 address. The I2C address would be 0x6A for write or 0x6B for read. In the 7-bit format, the I2C address translates to 0x35. Code ...

The I2C example was named “Wire” in the Arduino example. ProcedureIn this example, we use Ameba as the I2C master writer, and Arduino as the I2C slave receiver.When the I2C slave receives a string sent from I2C master, it prints the received string....
There are both 7- and 8-bit versions of I2C addresses. 7 bits identify the device, and the eighth bit determines if it's being written to or read from. The Wire library uses 7 bit addresses throughout. If you have a datasheet or sample code that uses 8 bit address, you'll want t...

2. I2C通讯内容多了一点,虽然使用Wrie库依旧能节省很多在信号时序、读写延迟上的代码量,但是读写的数据要做类型变换,指针引用、寻址读写过多,考虑搭建外部电路还挺麻烦,这个留在大家对arduino更熟悉以后再说3. 在几年以前,即便使用内置EEPROM,读写也要按照Wire库那种比较麻烦的形式开展,所以网上有大量 基于 EEPROM...

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) ...
MPU6050的数据接口用的是I2C总线协议,因此我们需要Wire类库的帮助来实现Arduino与MPU6050之间的通信。 MPU6050的数据写入和读出均通过其芯片内部的寄存器实现,这些寄存器的地址都是1个字节,也就是8位的寻址空间,其寄存器的详细列表说明书请点击下载: https://www.olimex.com/Products/Modules/Sensors/MOD-MPU6050/resources...
