interrupt service routine (isr) is the most important peripheral accessing method.
中断是主机与外部设备交互的最重要的方法。
at last, in the section of software design, startup code programming, operating system choosing and transplanting, task design, drivers design and interrupt service routine design had been discussed.
this article helps device driver developers test the interrupt service routine as much as possible by simulating the various interrupts.
本文通过模拟各种中断,尽可能地帮助设备驱动程序开发人员测试中断服务例程。
code generated for silicon labs single-cell c80519xxf by a non-ocg compiler results in an average of 108 cycles to execute the interrupt service routine and main loop overhead for each sample of data.
