基于LM3S2948芯片的一个火车运行沙盘的控制程序，程序经过严格验证过应用在一个发布会上。速度用PWM控制，红外IO采集到站状态，自己写的一个验证的滤波程序。(Based on a train running sand table LM3S2948 chip control program, application procedures rigorously validated in a release. Speed with PWM control, infrared IO collection station status, himself wrote a validation of the filtering process.)

液晶1602万年历显示 ① 利用单片机内定时器，通过软件编程方式实现年、月、日、星期、时、分、秒7个参数的运行。 ② 按大、小月显示月末日期。 ③按24小时制显示时、分、秒。 ④通过2个外接独立键盘实现对“万年历”的日期和的时间调整。 (602 liquid crystal display calendar The use of single-chip microcomputer timer, through software programming to achieve the year, month, day, week, hours, minutes, seconds, 7 parameters of the operation. According to the end date, Xiaoyue display. According to the 24 hour system shows hours, minutes, seconds. Through the 2 external independent keyboard implementation date and time adjustment of calendar .)
