对于 Holtek 八位元单片机来说，堆栈资源往往是有限的。例如，HT48R10A-1 就只有两级堆栈。 本文将介绍如何利用软件堆栈来解决这一问题。软件堆栈是用通用数据寄存器来保存返回地址的， 现在，它已经可以应用于HT48R10A-1、 HT48R30A-1、 HT48R50A-1、 HT48R70A-1 这几款单片 机，而且，软件堆栈也将很容易应用于其他单片机。

为了有效地提升铅酸蓄电池的使用寿命，同时实现对充电过程的监控，设计出一种用单片机控制的36 V铅酸蓄电池充电电源。本电路采用反激式拓扑，连续电流工作模式，电源管理IC设计在电源的副边，由ELAN公司的EM78P258N单片机模拟，是用可编程器件模拟电源管理IC，实现智能电源低成本化的一次成功尝试，通过对单片机的软件设计实现了充电电源的状态显示、充电时间控制、报警、过温保护、过压保护、过流保护等功能。本充电器真正的实现了铅酸蓄电池的三段式充电过程，其最高输出功率可达90 W，效率约85%，成本不到20元，具有很高的市场竞争力。 Abstract: In order to extend the life of lead-acid battery efficiently and supervise the charging process meanwhile， a 36V lead-acid battery charge powe supply controlled by microcontroller is designed. The charger is flyback switching power supply and works in CCM mode. A EM78P258N microcontroller made by ELAN microelectronics corporation is used as power management IC which is designed at the secondary circuit. The project is a successful attempt to low-cost intelligent power used microcontroller simulating power management IC. The charger also has the functions of the status reveal， charge time control， alarming， thermal protect， current limit and overvoltage protect by the software design. The circuit actually implements the three-step charge process， whose power is up to 90W and whose efficiency can get 85%. The net cost of this charger is less than 20 RMB， so that the charger is of powerful market competitiveness.

在汽车发动机起动时，若发动机起动后起动机不能及时断电，将会烧毁起动机或损坏飞轮齿环；若变速器不在空档位置起动，则起动机的瞬间动力将使汽车位移，还可能引起交通事故和人身安全。为此介绍一种利用NXP P89LPC901单片机控制的汽车起动保护控制器，通过检测汽车起动开关、变速箱档位、发动机转速，实现对汽车发动机起动过程检测和保护。起动保护控制器在发动机起动过程中通过采用逐个关闭打开负载系统，解决汽车发动机过程中因起动电流大而对汽车电源的冲击影响,延长了电瓶寿命。 Abstract: When the automotive engine is started, the engine start motor and flywheel gear may be damaged， even traffic accidents and personal safeties may be caused by wrong operation or other factors.In order to ensure the automotive engine can be started normally and safely,it is necessary that the protecting measures and methods are considered in the automotive electrical control system.This paper introduces a kind of the automotive engine starting protect controller based on NXP P89LPC901 MCU.The controller can protect the engine starting process by detecting the starter key switch,transmission stall and engine speed.Through the use of close and open load system,the controller can solve the impact on automotive power because of the high-current load in the process of the automobile engine starting, and extend battery life.
