COM_customplot
说明: 自己用的小软件,仿造原子的XCOM功能,加了一下自己用的功能。
1、基本串口通讯,鼠标放入串口选择自动刷新,显示COM口的驱动类型。
2、多条发送界面,可定时发送,可关联数字键盘、右键发送按钮可更改按钮名称,方便记忆。
3、485通讯,数据有十进制和十六进制可选,发送后自动保留记录。
4、CRC校验小工具。
5、十六进制通信协议提取部分位并根据自定义数据类型转化为十进制
6、字符格式示波器,例:">P:-1.25",示波器显示曲线名称P,数值-1.25,曲线个数最多8个。
7、类似MODBUS协议截取第2-5位,合成一个int数值,然后示波器显示波形,最多5个曲线
8、示波器曲线可键拖拽、放大(QT serial port assistant, plus digital oscilloscope)
