AMBA_3_AHB-Lite

使用89S52单片机对DS18B20进行驱动，在数码管上显示当前温度。(DS18B20 using 89S52 microcontroller to drive on, in the digital pipe display the current temperature.)

一个模拟电子表的程序，有兴趣的可以研究研究(a simulated electronic watches the proceedings, interested can studies)

说明：  一个特别好的modbus从机扫描程序，可以以RTU或ASCII方式通信以此来检验下位机。(A particularly good modbus slave scanner can communicate with RTU or ASCII way to test this lower position.)

通过把开机次数记录在24C02中，并在数码管上显示出来， 124C02的写保护脚为低电平，即允许写(Boot number of records in the 24C02, and displayed on the digital 124C02 write-protect pin is low, that is allowed to write)

at89c52的示例程序，简单的介绍了led的是使用(At89c52 example program, little led is used)

AD7705的采集12864显示，以及PCB电路，加工过了，可以使用(It is about the AD7705)

energy emwin驱动程序，可驱动彩屏及相关LCD控制器(energy emwin)

FreeRTOS_KL16FreeRTOS是一个迷你的实时操作系统内核。作为一个轻量级的操作系统，功能包括：任务管理、时间管理、信号量、消息队列、内存管理、记录功能、软件定时器、协程等，可基本满足较小系统的需要(FreeRTOS is a mini real time operating system kernel.
