Abstract: Nowadays there are many hardware communications protocols to choose from, UART, SPI, I2C three protocols are the most representative, they are widely used. They have different ...
在2440开发板上,有两个接口SCL和SDA,其中SCL是时钟线,SDA是数据线,他们分别连接一个上拉电阻(控制SDA的电平和SCK电平),这两条线上挂载了许多设备,这些设备也有两条线,分别连接ARM的SCL和SDA。 那么我们怎么传输数据? 比如说和一个存储芯片连接,我们 ...
