使用IIC协议可以通过两根双向的总线数据线SDA 和时钟线 SCL 使arduino 连接最多128个 IIC 从机设备。 与串口通信的一对一通信方式不同,总线通信通常有主机和从机之分。通信时,主机负责启动和终止数据传送,同时还要输出时钟信号;从机会被主机寻址,并且响应主机的通信请求;在IIC通信中,通信速率的控制有主机完成,主机...

The SCL & SDA pins of Mega 2560 R3 board connects to beside the AREF pin. Additionally, there are two latest pins located near the RST pin. One pin is the IOREF that permit the shields to adjust the voltage offered from the Arduino board. Another pin is not associated & it is kept f...
and 127. However the addresses from 0 to 7 are not used because are reserved so the first address that can be used is 8. Please note that a pull-up resistor is needed when connecting SDA/SCL pins. Please refer to the examples for more informations. MEGA 2560 board has pull-up ...
TWI接口(20(SDA)和21(SCL)):支持通信接口(兼容I2C总线)。 3.AREF:模拟输入信号的参考电压。 4.Reset:信号为低时复位单片机芯片。 The MEGA 2560 is designed for more complex projects. With 54 digital I/O pins, 16 analog inputs and a larger space for your sketch it is the recommended board for...
23脚(A4)为双向数据线SDA,24脚(A5)为时钟线SCL。 支持通信接口,兼容I2C总线。 外部中断引脚(D2、D3):5脚、6脚 触发中断引脚,可设成上升沿、下降沿或同时触发。 INT0(芯片中断号):D2(映射引脚号)为int0(Arduino中断号)。 INT1(芯片中断号):D3(映射引脚号)为int1(Arduino中断号)。
Arduino hardware package for ATmega64, ATmega128, ATmega165, ATmega169, ATmega325, ATmega329, ATmega640, ATmega645, ATmega649, ATmega1280, ATmega1281, ATmega2560, ATmega2561, ATmega3250, ATmega3290, ATmega6450, ATmega6490, AT90CAN32, AT90CAN64 and AT90CA
To start, you get a nice prototyping area underneath your Feather, with extra pads for ground, 3.3V and SDA/SCL. Not one to stop there, we expanded the PCB out to 2" x 2.5" with 3.5mm pitch terminal blocks down each side. There's... Notify Me, Assembled Terminal Block Breakout ...
The new connections provide a pin (IOREF) for shields to detect the analog reference voltage (so that analog input values can be correlated with the supply voltage), and SCL and SDA pins to enable a consistent pin location for I2C devices. The location of the I2C pins had varied on some...
The Mega 2560 R3 also adds SDA and SCL pins next to the AREF. In addition, there are two new pins placed near the RESET pin. One is the IOREF that allow the shields to adapt to the voltage provided from the board. The other is a not connected and is reserved for future purposes. ...
