I2C接口是一种两线接口,实现传输速度从中速到高达几兆位每秒的高速半双工串行通信接口。I2C系统包括一个寻址系统来识别I2C总线上的多个I2C从器件。一个I2C系统可以有一个或多个主器件。I2C系统有两根双向信号线:SDA(串行数据)和SCL(串行时钟)。I2C总线的重要电气特性是,它们都是由集电极开路输出端口组成,并通过上拉...

PSoC4 SCB as SMBus Slave and I2C EEPROM simultaneously. Hi, I need to set up a PSoC 4 SCB to be two I2C slave devices. If it receives one I2C address it must respond as an SMBus Slave, if it revieves another I2C addr... Show more Mikers Level 2 2...

Another shortcoming is, as mentioned, that the code runs only on AVR MCUs (because it uses assembler). If you want to use a software I2C library on the ARM platform, you could usehttps://github.com/felias-fogg/SlowSoftI2CMaster, which uses only C++ code. Because of this, it is much...
