51上的RTOS，该RTOS为非占先式多任务操作系统，如果用户任务的最长执行时间小于 系统节拍时间，则本MiniRTOS要优于占先式TOS。因为本MiniRTOS占用资源小，RAM不超过20字节，程序空间只占为600多字节。-51 on the RTOS, the RTOS non-preemptive multitasking operating system, if the user of the longest task execution times smaller than system beats time, it is superior to the MiniRTOS Preemptive 200040. Because of the small resources MiniRTOS occupation, RAM no more than 20 bytes, procedures only for the space of more than 600 bytes.

本程序运行于C8051F330，功能为接收遥控器发出的红外信号，然后等待上位机通过I2C总线来读取。IR数据接收完毕后，不再采集新的IR数据，一直等待上位机将数据取走后才开始准备接收新的IR数据-this program running on the C8051F330, functional remote control device to receive the infrared signal, Then wait for the PC through the I2C bus to read. IR data receiving end, not the acquisition of new IR data have been waiting for the PC will be removed after data began preparing to receive the new IR data

NS12864R测试程序 实现NS12864的相关操作，程序使用keilc编写，是C语言程序。能很好的移植到其他编译器中，已成功编写了飞思卡尔单片机的相关驱动。-NS12864R test procedure NS12864 realize the relevance of the operation, procedures used to prepare keilc is the C language program. Transplant well to other compilers have been successfully prepared a Freescale SCM-related drive.
