It's a uart driver to fast development.
Your can use this code to fast fit common uart protocal.
There are five kind type in UartDriver.h enum type { frame_header, frame_end, frame_data, frame_cnt, frame_check };
- frame_header : common use of the header of frame , you can also use it to fixed data. So you can have multiple frame_header.
- frame_end : common use of the end of frame. Note that once you receive the frame_end, however if the data is right ,the frame will be end.
- frame_data : common use of the data. When you need add multiple data. Use the AddLayer Function like AddLayer(MyUartDriver::frame_data,cnt). The cnt represent the data number you want to add.
- frame_cnt : Represent the not fix number of data. Your will receive frame_cnt data.
- frame_check : like frame_data. Your need to check the data after your receive a whole frame.
