用于Linux下的触摸屏驱动，使用在2.6.15版本内核上，可以作为两种方式使用，运行可靠稳定。-For the Linux driver under the touch screen, use the version in the 2.6.15 kernel, it can be used as two ways, reliable operation and stability.

研究了一种基于嵌入式系统和超声波测距系统的设计方案。应用移植嵌入式操作系统并给出障碍物检测优化方法，并且根据超声波测距的工作原对障碍物进行距离测量。实验结果表明，该系统在自然盲道情况下达到了处理实时性和判断的准确性要求，可较好地服务于盲人的独立出行。

所有的代码都要经过我自己，和他们工作得很好。它包括几个 C 文件和 H 文件，其中包含的某些功能。轻松地调用这些函数可以初始化 C8051 芯片。

应用背景The CMX990 provides, on-chip: a flexible, formattable GMSK packet and freeformat modem, a dual synthesiser fed from an external source, IF and RF transceiver stages for both Rx and Tx modes, and auxiliary ADCs and DACs for system control and monitoring.关键技术Operating in the range of 400MHz to 1GHz at data rates of 4 to 16 kbps. This single-chip, half-duplex device requires a minimum of external components, keeping end-product board size, power consumption and cost to an absolute minimum. The versatile GMSK modem is configured for either packet and freeformat data operation via an efficient task-oriented Rx and Tx format and command structure combined with data scrambling, interleaving and FEC and CRC capabilities. Rx data acquisition, extraction and tracking functions use Rx data-quality feedback to support varying signal environments. IF and RF functions in the Tx path handle all the signal processing requi

使用51单片机的输入口P3作为驱动口，步进电机使用的是4相电机28BYG-48，使用ULN2003作为驱动芯片，P3.0控制A相，P3.1控制B相，P3.2控制C相，P3.3控制D相，通过循环遍历数值表，使P3.0-P3.3交替产生高脉冲，频率不宜过高，太高的话步进电机只会内部振动，并不转动。相邻高电平之间的时间间隔在1-10ms之间就可以了
