单片机编程 MCS51系列单片机软件控制复位的可靠方法

MCS51系列单片机软件控制复位的可靠方法:文章指出了一种广泛流传的误解:在MCS-51系列单片机中,只要用指令使程序从起始地址开始执行,就可以复位单片机,摆脱干扰。通过实验,揭示了软件控制复位的可靠方法。有的单片机(如8098)有专门的复位指令,某些增强型MCS-51系统单片机虽然没有复位指令,但片内集成了WATCHDOG电路 ...

单片机编程 Emulating a synchronous serial

The C500 microcontroller family usually provides only one on-chip synchronous serialchannel (SSC). If a second SSC is required, an emulation of the missing interface mayhelp to avoid an external hardware solution with additional electronic components.The solution presented in this paper and in the a ...

单片机编程 Input Signal Rise and Fall Tim

All inputs of the C16x family have Schmitt-Trigger input characteristics. These Schmitt-Triggers are intended to always provide proper internal low and high levels, even if anundefined voltage level (between TTL-VIL and TTL-VIH) is externally applied to the pin.The hysteresis of these inputs, howeve ...
