Description

数据传输方法和移动终端 技术领域
本发明实施例涉及移动终端领域，并且更具体地，涉及一种数据传输方法和移动终端。
背景技术
在某些情境下，我们需要移动终端(如手机)的处理器输出多种格式的接口数据，例如I2C(Inter－Integrated Circuit)，通用异步收发传输器(Universal Asynchronous Receiver/Transmitter，UART)，串行外设接口(Serial Peripheral Interface，SPI)等，但是在移动终端的处理器的专用接口数量不足的情况下，就需要用通用输入/输出(General Purpose Input Output，GPIO)口来模拟其他接口形式，这时就需要处理器通过延时来控制何时发送接收数据/时钟。对与I2C，SPI这种同步数据来说，延时可以不需要太准，只要时钟和数据可以对得上，就可以通过时钟触发准确的完成数据的发送及接收。但是对与UART这种异步通信来说，接收端检测到起始位后，是通过延时来采集数据的，如果延时不准就很容易导致数据的接收错误，因此，延时的准确性对于GPIO模拟UART串口就极为重要。
移动终端的处理器一般会同时执行多种任务，但是要让其保证延时的准确性，就必须要求锁住处理器，屏蔽掉所有的中断响应，保证在运行延时函数时，处理器不会被其他中断打断，去处理其他事物，而导致延时超时。这样就会引起另外一个问题，如果模拟的UART串口传输的数据过长，就需长时间锁住处理器，会导致各种中断来不及处理，最终处理器会崩溃死机。
