MCD1实战入门篇,点亮单个LED的程序。 该实战的目的作为学习和应用MCD1在线调试工具套件，进行项目的软件和硬件 联合调试的范例程序，也就是当做一个用户程序实例，而演示板暂时充当用户电 路的角色。这样就构成了一个软件、硬件齐全的自制项目模拟环境。 本程序实现的功能是，把端口RC的8条引脚全部设置为输出模式，并让RC0 送出高电平，从而点亮RC0口的一个LED。 该程序可用于PIC16F87X(A)所有系列-Actual entry MCD1 articles, a single LED lit procedures. The real purpose for learning and application debugging MCD1 online suite of tools to carry out the project software and hardware examples of joint commissioning procedures, that is, as a user instance, and the demo board temporarily to serve as the role of the user circuit. This constitutes a software, hardware, a full range of home-made simulation environment projects. Realize the function of this procedure is that the 8-port RC pin all set to output mode, and sent high RC0, so I lit RC0 a LED. The program can be used to PIC16F87X (A) of all series

模拟银行卡取款操作，银行卡号为8位，能够进行查询、取款、存款、修改密码等操作。查询时需要输入密码，密码为6位。当密码位数和相应位都符合时，显示卡内余额，否则密码三次错误，结束操作。取款时也需要输入密码，密码为6位。当密码位数和相应位都符合时，显示现有余额，输入取款金额，操作结束显示所剩金额，否则密码三次错误，结束操作。限制每天总共可取的金额 ，若违规给出相应的警告。取款操作时输入取款金额 ，操作结束，显示卡内余额，输入密码时，不显示真实值，修改密码时显示真实值。-simulated bank teller card operation, a registered member of the eight to conduct inquiries, withdrawals, deposits, change passwords operation. Inquiries need to enter a password, the password to six. When the median and the corresponding password-meet, showed the card balance, otherwise the wrong password three times, the end of operation. Teller also need to enter the password, the password to six. When the median and password are consistent with the corresponding position, shows that the existing balance of the amount imported withdrawals, the remaining operation ended shows the amount, otherwise the wrong password three times, the end of operation. Limit daily total amount of desirable, if irregularities are given corresponding warning. ATM withdrawals
