随着单片微机在各个领域中的应用越来越广泛,对其可靠性要求也越来越高。单片机系统的可靠性由多种因素决定,其中系统抗干扰性能是可靠性的重要指标。本文介绍了硬件及软件单片机抗干扰的方法,从而全面提高系统的可靠性。 With the application of single-chip microcomputer in various fields more and more widely, its reliability requirements are also getting higher and higher. The dependability of the one-chip computer system is decided by many kinds of factors, among them the anti-interference performance of the system is an important indicator of reliability. This article describes the hardware and software microcontroller anti-jamming methods, thereby enhancing overall system reliability.
