51单片机低功耗地温检测的上位机软件 通过串口读取单片机ROM存储的温度数据并具有画出图象、记录测试时间、保存为文档保存等功能-51 Single-chip low-power ground temperature detection of PC software to read through the serial port single-chip temperature data stored in ROM and have painted images, records, testing time, save it as a document preservation and other functions

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.
