段式液晶驱动芯片BU9792驱动程序,也是低功耗的,是日本设计的,非常不错啊。(Segment LCD Driver IC BU9792 driver, but also low-power, is a Japanese design, very good ah.)

用c语言编写的产生正态随机数的源代码: 算法一产生12个（0，1）平均分布的随机函数，用大数定理可以模拟出正态分布。 算法二用到了数学中的雅可比变换，直接生成正态分布，但此算法在计算很大规模的数时 会出现溢出错误。 (With the c language normal random number generation source code: Algorithm 1 produces 12 (0,1) the average distribution of the random function, with large numbers theorem can be simulated normal distribution. Mathematical algorithms used in the two Jacobi transformation, directly generate a normal distribution, but this algorithm is very large in the calculation occurs when the number of overflow error.)

通讯录设计一个通讯录管理系统，每条记录包括：联系人姓名、性别、电话、住址、Email等。系统功能要求：（1）显示通讯录所有内容。按联系人姓名首字母排序，并统计共有多少条记录。（2）查询通讯录。可按联系人姓名或电话号码查询，将查询结果整条记录输出到屏幕。（3）修改通讯录。通过查询功能，找到需要修改的记录，并修改内容。在修改记录前显示是否要删除的提示。（4）添加记录。需要判断新添加的记录是否存在，若存在终止该操作。（5）删除指定记录。通过查询功能，找到要删除的记录。在删除记录前显示是否要删除的提示。（6）退出通讯录管理系统。
