SCCB协议和I2C协议的区别 SCCB是简化的I2C协议，SIO-l是串行时钟输入线，SIO-O是串行双向数据线，分别相当于I2C协议的SCL和SDA。SCCB的...
-SCCB protocol and I2C protocol differences
SCCB is to simplify the I2C protocol, SIO-l is the serial clock input line, SIO-O is a bidirectional serial data line, respectively, equivalent to the I2C protocol SCL and SDA. SCCB and I2C bus timing is basically the same, the response signal ACK is called a transmission unit of the first nine, divided into Don t care and NA. Don t care bits generated by the slave NA bits generated by the master, the SCCB does not support multi-byte read and write, NA bit must be high. In addition, SCCB did not repeat the initial concept, so the SCCB read cycle, when the host sending the on-chip register address, you must send a bus stop conditions. Otherwise, send the read command, the slave will not respond to signals generated Don t care.
SCCB as I2C and some nuances, so the use of GPIO analog SCCB bus way. SCL pin is always connected to the output mode is set, and the SDA pin is connected to the data transfer process, by setting the value of IODIR
