前言

上一篇文章TP屏幕适配--驱动篇 介绍了TP屏幕底层驱动处理以及按键处理上报，这篇文章主要讲到UI界面如何对TP底层上报的按键手势等信息响应处理。

TP的上报处理流程

TP触屏信息上报的函数处理流程如下图所示：

graph LR start[开始]-->B(底层上报TP触屏信息) B-->C(TPCallBackFunc) C-->|当触屏在LCD屏内|D(MMK_DispatchExtSig P_TPP 正常发tp消息) C-->|当触屏在LCD屏外|E(MMK_DispatchExtSig KPDSVR 转成物理按键消息) D-->|LCD屏内坐标处理|F(MMK_DispatchMSGTp) E-->|按键码处理|G(MMK_DispatchMSGKbd) F-->|按下|F1(DispatchMSGTpDown) F-->|抬起|F2(DispatchMSGTpUp) F-->|移动|F3(DispatchMSGTpMove) G-->DEAL F1-->DEAL F2-->DEAL F3-->DEAL DEAL(各个UI窗口处理) DEAL-->|处理完成|END[结束]

LCD屏内函数处理
