Cypress触摸芯片自己做的demo 代码

1.前言

（1）cyprees芯片主要是可以做一些触摸的检测并实现一些IO输出，使用的工具psoc creater
（2）psoc creater 可以i直接通过GUI的方式配置一些GPIO的状态以及集成的功能模块，编译后，我们可直接通过include 对应的头文件后，可在主函数中直接调用相关的接口，基本不怎么编写代码了

2.工程使用逻辑

• 如下图为工程主界面：

• • topDesign：可以从右边拖一些关键的功能过来，并配置一些基础参数
• • PIN： 对一些功能进行功能进行对应的管脚进行对应
    

• 对上图进行详细介绍说明的
  – 一个capsense 进行触摸检测
  – 6个led灯

• capsense的配置截图如下：

• led的配置如下： 注意不要勾选HW connection

3.主函数逻辑

完成如上配置后，点击编译后会出现自动声场相关功能模块，我们需主要在main函数中进行编辑即可：

#include "CapSense.h"
#include "project.h"#define LED_ON						(0u)
#define LED_OFF						(1u)
void LED_Write(uint8 value);
uint8 LED_Read(void);uint8   LED1_Read(void);
void    LED1_Write(uint8 value);uint8   LED2_Read(void);
void    LED2_Write(uint8 value);
uint8   LED3_Read(void);
void    LED3_Write(uint8 value);
typedef enum
{SENSOR_SCAN = 0x01u,                WAIT_FOR_SCAN_COMPLETE = 0x02u,     PROCESS_DATA = 0x03u,               
} DEVICE_STATE;int main(void)
{CyGlobalIntEnable; /* Enable global interrupts. *//* Place your initialization/startup code here (e.g. MyInst_Start()) *//* Start CapSense block - Initializes CapSense Data structure and performs first scan to set up sensor baselines */DEVICE_STATE currentState = SENSOR_SCAN;  CapSense_Start();/* Scan all widgets *///CapSense_ScanAllWidgets();for(;;){/* Place your application code here. *//* Place your application code here. *//* Do this only when a scan is done *//* Process all widgets */CapSense_ProcessAllWidgets();/* Include Tuner */ // CapSense_RunTuner(); /* Scan result verification */if (CapSense_IsAnyWidgetActive()){/* Add any required functionalitybased on scanning result*/}/* Start next scan */switch(currentState){case SENSOR_SCAN:/* Initiate new scan only if the CapSense block is idle */if(CapSense_NOT_BUSY == CapSense_IsBusy()){#if ENABLE_TUNER/* Update CapSense parameters set via CapSense tuner before the beginning of CapSense scan */CapSense_RunTuner();#endif/* Scan widget configured by CSDSetupWidget API */CapSense_ScanAllWidgets();/* Set next state to WAIT_FOR_SCAN_COMPLETE  */currentState = WAIT_FOR_SCAN_COMPLETE;}break;case WAIT_FOR_SCAN_COMPLETE:/* Put the device to CPU Sleep until CapSense scanning is complete*/if(CapSense_NOT_BUSY != CapSense_IsBusy()){CySysPmSleep();}/* If CapSense scanning is complete, process the CapSense data */else{currentState = PROCESS_DATA;}break;case PROCESS_DATA:/* Process data on all the enabled widgets */CapSense_ProcessAllWidgets();/* Controls LEDs Status based on the result of Widget processing. *///LED_Control();LED_Write(CapSense_IsWidgetActive(CapSense_BUTTON0_WDGT_ID ) ? LED_OFF : LED_ON );LED1_Write(CapSense_IsWidgetActive(CapSense_BUTTON1_WDGT_ID ) ? LED_OFF : LED_ON );LED2_Write(CapSense_IsWidgetActive(CapSense_BUTTON2_WDGT_ID ) ? LED_OFF : LED_ON );LED3_Write(CapSense_IsWidgetActive(CapSense_BUTTON3_WDGT_ID ) ? LED_OFF : LED_ON );LED4_Write(CapSense_IsWidgetActive(CapSense_BUTTON4_WDGT_ID ) ? LED_ON : LED_OFF );LED5_Write(CapSense_IsWidgetActive(CapSense_BUTTON5_WDGT_ID ) ? LED_ON : LED_OFF );/* Set the device state to SENSOR_SCAN */currentState = SENSOR_SCAN;  break;  /******************************************************************** Unknown power mode state. Unexpected situation.******************************************************************/    default:break;} //CyDelay(10);}
}

4.程序下载

1. 编译工程完成HEX文件
2. 打开psoc programmer 软件，选择对应的芯片iC，选中hex文件，点击下载：
4. 使用效果如下
5. 按下去的时候灯光灭掉，松手灯光亮起来

结论

本文通过查找简单的工程代码实现了一个触摸控制灯光亮灭场景。如有任何问题评论区交流。
