TI 论坛、您好!
我正在尝试在以下代码中为 LED2添加更长的延迟。 我尝试了使用__delay_cycles、但最多可以达到15秒左右。 如果我增大该值、则会编译代码、但不起作用。
我尝试实现的是以下目标、
1.用户触摸按钮(进入 CAPT_APPHAN德勒())
2.输出 LED2 (30秒始终开启、无切换)和输出 LED1 (30秒、但快速切换、以降低功耗
3.回到睡眠状态。
下面是我的代码:

The application handler manages // whether the user interface (UI) is running in full active scan mode, or // in a low-power wake-on-proximity mode. // // The CapTIvate application handler will return true if proximity was // detected on any of the sensors in the application, which is used here // to control the state of LED2. LED1 is set while the background loop enters // the handler, and is cleared when the background loop leaves the handler. // // \version 1.83.00.05 // Released on May 15, 2020 // //***************************************************************************** #include <msp430.h> // Generic MSP430 Device Include #include "driverlib.h" // MSPWare Driver Library #include "captivate.h" // CapTIvate Touch Software Library #include "CAPT_App.h" // CapTIvate Application Code #include "CAPT_BSP.h" // CapTIvate EVM Board Support Package void main(void) { // // Initialize the MCU // BSP_configureMCU() sets up the device IO and clocking // The global interrupt enable is set to allow peripherals // to wake the MCU. // WDTCTL = WDTPW | WDTHOLD; BSP_configureMCU(); __bis_SR_register(GIE); // // Start the CapTIvate application // CAPT_appStart(); // // Background Loop // while(1) { // // Run the captivate application handler. // Set LED1 while the app handler is running, // and set LED2 if proximity is detected // on any sensor. // if(CAPT_appHandler()==true) { LED2_ON; __delay_cycles(300000000); } else LED2_OFF; // // This is a great place to add in any // background application code. // __no_operation(); // // End of background loop iteration // Go to sleep if there is nothing left to do // CAPT_appSleep(); } // End background loop } // End main()
