记得没多久前还用一款串口调试助手来画曲线，现在却怎么也不知道软件的名字了。无奈！
想看原始数据的变化，SerialChart_v034这款软件试了试，的确还不错。
打开后需要自己写下配置文件
[_setup_] port=COM3 baudrate=115200 width=1000 height=400 background_color = white grid_h_origin =100 grid_h_step = 10 grid_h_color = #EEE grid_h_origin_color = #CCC grid_v_origin = 100 grid_v_step = 10 grid_v_color = #EEE grid_v_origin_color=transparent [_default_] min=-0.3 max=1.5 [1] color = green [2] color = blue [3] color = red [4] color = green [5] color = blue [6] color = red
上边这段代码就是6个数据的曲线，发过来一条逗号分割的6个数据就可以自动画出曲线了。性能也不错。
