Overview
This document is a substantially periodic describing the project, and the need to implement the process of content.

Platform development plan
Since the platform has not yet come out, so the final estimate of time is not good software, but the software can be preliminary tasks to be achieved can evaluate it.
Hardware planning steps:
- Selection roughly the end of the end of March;
- The core board schematics ended in mid-April;
- Layout territory ended in mid-May;
- Welding Schematic substantially completed before the end 6;
- Early July to complete the power-on debugging;
- The end of July the FBI;
- In mid-August to complete the final prototype.
Software planning steps:
Due to a combination of hardware debugging software debugging, so the time is not good forecast, and so when the ANDROID 9.0 software platform of choice, you need to 200G of the environment, to build a longer period, and has a certain relationship with the hardware cycle, time is not detailed care set, but the time required by the overall environment will be set up by July, the end of July the FBI, the end of August to complete the final prototype:
BSP plan:
- Environmental structures;
- Core board firmware transplantation;
- Logo production;
- The FBI;
- optimization.
UI plan:
- Environmental structures;
- Android file system cutting;
- Debug module function (wifi, serial port, usb, touch);
- The FBI;
- optimization.

design style
All current design, the class must be allocated according to the manner function module. To facilitate cutting, each module must be independent. In designing the module, structured as possible, unrelated modules, physical and non-operational level not mix.
