2.将曝光时间和曝光时那一帧数据的最大值显示在浮窗上； 3.优化浮窗显示内容，将内容密度提高，不需要下滑浮窗就能看见所有信息； 4.浮窗第一行为滚动显示区域； 5.错误控制； 6.判断ximeaAirborneSystem系统是否存活：测出有bug，相关代码已经注释掉；
Payload SDK package directory structure introduction: doc/psdk_other_docs/psdk_code_style: Template files described code style of Payload SDK. doc/simple_model: Some structural models of Skyport 1/Skyport 2/X-Port and aircraft. The structure models provide convenience for users to design payload structure. psdk_lib/api_headers: Header files of Payload SDK, describing all API of Payload SDK. Users can understand features provided by Payload SDK and its usages relying on the header files. psdk_lib/lib: Library files of Payload SDK. Users select appropriate library file to use based on target platform. sample/api_sample: Sample code used to demonstrate usage of Payload SDK features. sample/platform: Sample code related to specific platform, including Linux and FreeRTOS platforms. sample/platform/linux/common/osal: OSAL layer implementation of Linux operation system. sample/platform/linux/manifold2: Sample project used on Manifold 2. sample/platform/rtos_freertos/common/osal: OSAL layer implementation of FreeRTOS operation system. sample/platform/rtos_freertos/psdk_development_board_1.0: Sample project used on Payload SDK development board 1.0. sample/platform/rtos_freertos/stm32f4_eval: Sample project used on STM32F4XX-EVAL development board. tools: Some tools used with Payload SDK.
