pxa270-关于PXA270的I2C总线共用的问题

问题描述 关于PXA270的I2C总线共用的问题 1.CPU使用PXA270 2.RTC使用外部芯片M41T81,使用IIC总线与PXA270进行通讯: 3.扫描头用来扫描二维码,使用IIC总线与PXA270进行通讯: 4.操作系统用的是wince5.0 问题描述: 当在注册表里注释掉扫描头的启动信息,不让其开机启动,这种情况下,RTC是可以正常工作的,能够在断电情况继续保持守时功能: 但是当我们在注册表里加上扫描头的启动信息,让其开机启动后,不管硬件上扫描头有没有接上,这时RTC都不能正常工作

fatal error:php中通过register

今天发现php中,如果要记录fatal error的时候,可以实用一个不错的函数, 叫register_shutdown_function,小结如下:   register_shutdown_function可以让我们设置一个当执行关闭时可以被调用的另一个函数.也就是说当我们的脚本执行完成或意外死掉 导致PHP执行即将关闭时,我们的这个函数将会被调用.所以,我们可以使用在脚本开始处设置一个变量为false,然后在脚本末尾将之设置为true的方 法,让PHP关闭回调函数检查脚本完成与否. 如果我们
