该程序uc/gui 是再linux(文本界面)环境下运行,需要用到/dev/fb,该版本和uc-GUI 3.24版源码（含VC下的示例程序)都是同一版本,只是运行环境不一样. -the program uc/gui is again linux (text interface) operating environment, the need to resort to/dev/fb, the version and uc-source GUI version 3.24 (including the VC sample program) is the same version, the operating environment is not the same.

HART协议由Rosemount公司开发且已向每个使用者开放HART协议采用标准的Bell 202频移键控信号以1200波特通信以低电平加载于4mA~20mA模拟信号上，由于载波信号的平均值为零所以它对模拟信号没有影响。-HART agreement develops by Rosemount Corporation also opened the HART agreement to each user to use the standard the Bell 202 frequency-shift keying signal increase by 1,200 bauds correspondences by the low level on the 4mA~20mA simulated signal, because intelligence signal mean value for zero therefore it has not affected to the simulated signal.

芯片启动ADC将信号采集端口电压的转换结果按转换数据和对应的模拟电压的形式通过串口发送到PC机屏幕上显示，打开串口调试精灵，正确设置通信格式，观察接收数据，不同的光照强度对应不同的等级，其通信格式：N.8.1, 9600。
