飞思卡尔S12 系列单片机系统硬件设计，详细介绍了该单片机的硬件使用，为全中文，MC9S12DG128B 有16路AD 转换，精度最高可设置为10 位；有8 路8 位PWM 并可两两级联为16 位精度PWM，特别适合用于控制多电机系统。它的串行通信端口也非常丰富，有2 路SCI，2 路SPI 此外还有IIC，CAN总线等端口，并且采用了引角复用功能，使得这些功能引角也可设置为普通的IO 端口使用。此外 它内部还集成了完整的模糊逻辑指令，可大大简化我们的程序设计。-Freescale s S12 family of single-chip microcomputer system hardware design, detail the use of single-chip hardware for the whole Chinese, MC9S12DG128B 16 Road AD conversion, the highest precision can be set to 10 are 8 and 8 PWM 22 Alliance for the 16-bit precision PWM, is particularly suitable for controlling multi-motor system. Its serial communication ports are also very rich 2-way SCI, 2 road SPI in addition to IIC, CAN bus, such as ports, and using the primers angle multiplexing function, so that these functions can also be cited angle is set to normal IO port to use. In addition, it also integrates the internal integrity of the fuzzy logic instructions, can greatly simplify the design of our procedures.

在做项目（工程）的时候，我们经常要用到比较多的按键，而且IO 资源紧张， 于是我们就想方设法地在别的模块中节省IO 口，好不容易挤出一两个IO 口，却 发现仍然不够用，实在没办法了就添加一个IC 来扫键。一个IC 虽然价格不高， 但对于大批量生产而且产品利润低的厂家来说，这是一笔不菲的开支! 那，我们能不能想到比较好的扫键方法：用最少的IO 口，扫最多的键？可以吗？-Doing the project (engineering), we often use the relatively large number of keys, and the IO resource constraints, so we are trying to save in another module IO ports, finally out of one or two IO ports, only to find is still not enough there is really no other way to add an IC to sweep on the keys. Although the price of an IC is not high, but low profits, high-volume production and product manufacturers, this is spending a lot of money! That, we can not think of a better scan key method: with a minimum of IO ports, scan Most of the keys? OK?
