# I2C Linux
## 1. I2C 简介
- 一种串行、半双工总线；主要用于近距离、低速的芯片之间的通信
- IIC总线有两根双向的信号线：数据线 SDA 用于收发数据，时钟线 SCL 用于通信双方时钟的同步
- IIC总线硬件结构简单，成本较低
- 一种多主机总线，连接在 IIC 总线上的器件分为主机和从机；主机有权发起和结束一次通信；从机只能被主机呼叫
- 当总线上…

目前action.yml 中对所有action中的bsp都做了scons检查，大家觉得，是不是提交的bsp没有对一些I2C 或者SPI 等做编译检查呀？会检查到吗？
- [ ] 根据修改的文件的目录寻找需要详细检查的bsp
- [ ] 对该bsp进行检查I2C, SPI, PWM , ADC, DAC 等其他驱动的编译情况。

If this is called on a system where the pull up isn't present then the project can hang…

The recent i2c/spi driver changes and corresponding board level support has been a solid step forward, but one small thing we've lost is the configuration of on board I2C devices. In many cases the I2…
