STM32单片机项目实例：基于TouchGFX的智能手表设计（7）MVP架构下的交互逻辑设计

发布时间：2023年12月19日

一、概述

? 本文例程是基于 TouchGFX 的智能手表设计—Designer 软件 UI 设计的例程?0B-2_STM32U575_MVP_Interactive工程的拷贝，用于MVP架构下的逻辑代码添加。

二、MVP架构下的交互逻辑

? 将资料光盘中的0B-2_STM32U575_MVP_Interactive例程拷贝至工程目录，并将文件夹重命名为0B-3_STM32U575_MVP_Interactive，打开…\0B-3_STM32U575_MVP_Interactive\TouchGFX 下的0B-2_STM32U575_MVP_Interactive.touchgfx，点击DialPage，在Interactions增加GoToAPP的硬件交互，用于表盘页面与APP页面的切换（硬件按键触发）。

? 点击ApplicationPage，在Interactions增加GoToDial的硬件交互，用于APP页面与表盘页面的切换（硬件按键触发）。

点击右下角的</>.生成代码，打开MDK工程，进行工程的全编译。

? 点击工程管理目录下的gui，打开MenuElement.cpp与MenuElement.hpp,在MenuElement.hpp中添加Scroll Wheel的相关函数声明。
