SDA (Serial Data) – The line for the master and slave to send and receive data. SCL (Serial Clock) – The line that carries the clock signal. I2C is a serial communication protocol, so data is transferred bit by bit along a single wire (the SDA line).

Data Validity START CONDITION: A high-to-low transition of SDA with SCL high is a start condition which must precede any other command (see Figure 3). STOP CONDITION: A low-to-high transition of SDA with SCL high is a stop condition. After a read sequence, the stop command will place the EEPROM in a standby power mode (see scl\sda 分别是什么意思？ 2018-05-19 最佳答案 sda----数据线 scl-----控制线 scl 用来宏定义与操作芯片时钟引脚连接的单片机引脚 sda 用来宏定义与操作芯片数据引脚连接的单片机引脚 在 i2c 总线上传送数据，首先送最高位，由主机发出启动信号，sda 在 scl 高电平期间由高电平跳变为低电平，然后由主机 SCL SDA IN SDA OUT Figure 2.

Hardware characteristics for long-distance transmission are then given by the chosen standard. Control of data transmission is the same as in normal I2C SDA (Serial Data) – The line for the master and slave to send and receive data. SCL (Serial Clock) – The line that carries the clock signal. I2C is a serial communication protocol, so data is transferred bit by bit along a single wire (the SDA line).

I2C. I2C can be used to connect up to 127 nodes via a bus that only requires two data wires, known as SDA and SCL.. SDA => D2. SCL => D1; SPI. SPI is much simpler than I2C.

Because of this, send() and receive() have been replaced with read() and write(). 2020-01-20 2020-05-27 2015-01-16 We can conveniently tie both the SCL and SDA pins together in order to achieve what we want. Note that tying SCL or SDA to Ground or Vcc will cause the BIOS to hang, as transitions between low and high are part of the I 2 C protocol. We can simply short the SCL and SDA pins together with a conductor such as a flat head screwdriver or a paperclip.

On the Arduino boards with the R3 layout (1.0 pinout), the SDA (data line) and SCL (clock line) are on the pin headers close to the AREF pin. The Arduino Due has two I2C / TWI interfaces SDA1 and SCL1 are near to the AREF pin and the additional one is on pins 20 and 21.

So RC is inverted RX1 for SBUS.

SDA SCL Der I2C-Bus ist gut für die Kopplung verschiedener Mikrorechner geeignet. Es können Systeme mit Prozessoren verschiedener Hersteller gekoppelt werden. Geht man von der Entwicklung eigener Leiterplatten aus, so sind die Preise der benötigten Komponenten für z.B. ein minimales Arduino-Systems gering. Es lohnt
