WebWhen SDA falls, SCL is high, which means it starts to work. This is used as the currently transmitted data. The falling edge of SCL is used as an adjustable signal for SDA information. Then you can adjust the level of SDA. IIC has three rate options: Normal mode (100kbps) Fast mode (400kbps) High speed mode (3.4Mbps) Web会员中心. vip福利社. vip免费专区. vip专属特权
