class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height:1.8;">本项目基本与本次训练营提供的基本原理图一致，下面将对几个较为特色的点进行阐述。</p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height:1.8;"> </p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height:1.8;">该项目在基本的示例项目上添加了CH343P作为串口通信元件，从而能够直接使用原有设计的供电Type C口进行串口通信，从而实现固件的烧录及相关功能。</p> <p class="paragraph

IP5306和IP3005A设计了充电电路和供电电路。不过需要注意的时，由于单片机电量消耗不大，推荐使用IP5306的遍体——IP5306-CK进行设计，该变体不会因为电流过小而自动休眠，保持常开供电，适合MCU应用供电。</p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto

pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height:1.8;"> </p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height:1.8;">系统使用瑞萨R7FA2E1A72DFL作为主控芯片，软件方面使用e2 studio作为主要开发软件，主要代码也基本和本次训练营所讲解、培训使用的代码相同，不过由于笔者没有jlink作为调试器，所以开发过程中的调试主要依靠串口进行输出。在整体调试流程中，由于没有jlink，最为困难的点是电容式触摸的调优和测试。下面将就这一点进行叙述。</p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height:1.8;">在使用串口进行调优时，按照课程教程，首先在“瑞萨视图>Renesas QE”中选择“CapTouch Workflow（QE）”打开工作流，选择对应的项目、并参考教程配置好电容式按钮。</p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height:1.8;"><img

Tuning（Serial）”并点击“Output Files”，生成测试程序</p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height:1.8;"><img src="//image.lceda.cn/pullimage/YlpfDOn6KiWpQskvJAV4flv7mr4raMb69ro7ZK9t.png" alt="" width="343" height="167"></p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height:1.8;">此时有两种可以选择的方案：1、直接参考“qe_touch_sample.c”，撰写主程序；2、在程序的主循环中声明并调用“qe_touch_sample.c”中的“void qe_touch_main(void)”，也可以实现这一步的工作。</p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height:1.8;"> </p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height:1.8;">同时，需要在配置中调整原有串口配置，将之前配置的串口配置到touch堆栈上，并且选择Touch堆栈，在属性界面中将“Support for QE Tuning using”切换为“Enabled”。</p> <table
