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.

SD卡驱动 SD_CARD_TIMEOUT 当一个SD卡的操作超出时限，将导致返回错误和该标记被置位 SD_CARD_EXIST 当卡槽内插入了合适的卡体，不管是什么卡，都会使该位被设置； SD_CARD_WRITE_PROTECT 当卡体的写保护开关被 LOCK 时，则该位被设置； SD_CARD_READY 当卡槽内的卡被正确识别，并可以随时访问时，则该位被设置； SD_CARD_DOOR_CLOSE 当卡槽的门（产品外壳上的挡板开关）关闭时，则该位被设置； SD_CARD_IS_SD 当卡槽内插入的是 SD 卡时，则该位被设置。 SD_CARD_IS_MMC 当卡槽内插入的是 MMC 卡时，则该位被设置； 注意：不要使用 0x80，免得和整数作逻辑运算时被误为负数。-err
