本文档记录CC2640R2F simple_peripheral_oad_onchip工程下抽象LED控制接口

硬件平台：官方 LAUNCHXL-CC2640R2F （http://www.ti.com/tool/cn/launchxl-cc2640r2）

SDK:  simplelink_cc2640r2_sdk_1_50_00_58  (http://www.ti.com/tool/download/SIMPLELINK-CC2640R2-SDK)

编译环境： iar for arm 8.20.2 (https://www.iar.com)

 

1、工程中增加led.c、led.h文件，增加头文件目录，修改宏定义

 

注：宏定义里面修改如下，红圆圈为修改项（关闭默认的LED_DEBUG 宏)

 

2、自定义LED引脚

CC2640R2F_LAUNCHXL.h 文件下修改

2.1、去掉默认LED定义引脚

 

 去掉有冲突引脚（红色圆圈)，增加自定义引脚(红色方圈)

 

2.2、CC2640R2F_LAUNCHXL.c 文件修改

 

2.3、led.c 文件

2.4、增加测试接口方式（simple_peripheral_oad_onchip.c）

系统启动后 绿灯以500ms频率闪烁5次

连接APP后红灯闪烁以200ms频率闪烁3次，绿灯常亮（函数 static void SimpleBLEPeripheral_processStateChangeEvt(gaprole_States_t newState)）

断开APP后红灯闪烁以200ms频率闪烁3次，绿灯常灭（函数 static void SimpleBLEPeripheral_processStateChangeEvt(gaprole_States_t newState)）

 

3、编译烧录，运行
