# EC718 Console

|
|
## mshell
|
|||
|
|
|
|||
|
|
通过串口指令扩展功能，实现测试和数据采集
|
|||
|
|
|
|||
|
|
* 实现通过LVGL输出到LCD屏幕
|
|||
|
|
|
|||
|
|
## python
|
|||
|
|
|
|||
|
|
* 将python组件分离为单独的subsys便于迁移，subsys只是用于建立快速任务，属于APP，而组件才是核心依赖文件
|
|||
|
|
|
|||
|
|
适配过程是通过参考其他平台的package结构，驱动大致包括open/close/ioctl_config/enable/disable/write/read等封装函数
|
|||
|
|
|
|||
|
|
* open/close用于初始化相关数据堆栈
|
|||
|
|
* enable/disable用于使能配置，init和deinit
|
|||
|
|
* config用于配置相关参数
|
|||
|
|
|
|||
|
|
再根据不同平台和不同SDK，适配出对应的底层C调用，相关的API头文件可以放在pikascript-api路径下
|
|||
|
|
|
|||

|

|
