pyks2
A python module to access the Kyowa KS2 binary file
By ZC. Fang Copyright © 2018
功能
-
读取KS2文件
数据采用int16存储，转化公式：
data = coefA * raw + coefB -
转存至.mat
仍然采用int16存储
-
基本的绘图功能（对高速采集信号进行下采样后绘出）
-
TODO:
- 增加导出excel, txt等功能
依赖环境
- Python >= 3.4
- Numpy >= 1.13
- Scipy >= 0.19
- Pandas >= 0.20
KS2版本要求
- ks2 version: 01.00
- csv version: 0 (old)
- No CAN channel
- No digital channel
使用
见run.ipynb
