[分享] CC1350 LunchPad-433MHz测评（一）——GPIO测试

FuShenxiao 2025-10-3 21:15 楼主

感谢EEWorld提供的CC1350 LunchPad-433MHz开发板测评机会，虽然这款开发板目前已经停产了，但是对于TI芯片的初学者还是挺有意义的

CC1350 LunchPad-433MHz是一款双频带无线开发板，可以在学习TI芯片的基础操作的同时学习TI的无线传输技术SimpleLink，该芯片数据手册与开发板原理图如下

GPIO的测试将基于CCS进行开发，为了实现对这款开发板的开发，需要安装以下几个链接的内容

CCSTUDIO IDE、配置、编译器或调试器 | 德州仪器 TI.com.cn

SIMPLELINK-CC13X0-SDK 软件开发套件 (SDK) | 德州仪器 TI.com.cn

ARM-CGT IDE、配置、编译器或调试器 | 德州仪器 TI.com.cn

进入CCS，选择开发板空白工程并创建

生成文件目录如下

观察生成的主函数，可以看到它使用了RTOS，并调用了mainThread这个线程

int main(void)
{
    pthread_t           thread;
    pthread_attr_t      attrs;
    struct sched_param  priParam;
    int                 retc;

    /* Call driver init functions */
    Board_init();

    /* Initialize the attributes structure with default values */
    pthread_attr_init(&attrs);

    /* Set priority, detach state, and stack size attributes */
    priParam.sched_priority = 1;
    retc = pthread_attr_setschedparam(&attrs, &priParam);
    retc |= pthread_attr_setdetachstate(&attrs, PTHREAD_CREATE_DETACHED);
    retc |= pthread_attr_setstacksize(&attrs, THREADSTACKSIZE);
    if (retc != 0) {
        /* failed to set attributes */
        while (1) {}
    }

    retc = pthread_create(&thread, &attrs, mainThread, NULL);
    if (retc != 0) {
        /* pthread_create() failed */
        while (1) {}
    }

    BIOS_start();

    return (0);
}

mainThread在empty.c中的定义如下，可以看到这里已经为我们定义好了基本的外设，并且实现了基本的闪灯逻辑

void *mainThread(void *arg0)
{
    /* 1 second delay */
    uint32_t time = 1;

    /* Call driver init functions */
    GPIO_init();
    // I2C_init();
    // SPI_init();
    // UART_init();
    // Watchdog_init();

    /* Configure the LED pin */
    GPIO_setConfig(Board_GPIO_LED0, GPIO_CFG_OUT_STD | GPIO_CFG_OUT_LOW);

    /* Turn on user LED */
    GPIO_write(Board_GPIO_LED0, Board_GPIO_LED_ON);

    while (1) {
        sleep(time);
        GPIO_toggle(Board_GPIO_LED0);
    }
}

修改empty.c中的内容，利用下降沿中断触发LED灯翻转电平

/*
 *  ======== gpioButtonFxn0 ========
 *  Callback function for the GPIO interrupt on Board_GPIO_BUTTON0.
 */
void gpioButtonFxn0(uint_least8_t index)
{
    /* Clear the GPIO interrupt and toggle an LED */
    GPIO_toggle(Board_GPIO_LED0);
}

/*
 *  ======== gpioButtonFxn1 ========
 *  Callback function for the GPIO interrupt on Board_GPIO_BUTTON1.
 *  This may not be used for all boards.
 */
void gpioButtonFxn1(uint_least8_t index)
{
    /* Clear the GPIO interrupt and toggle an LED */
    GPIO_toggle(Board_GPIO_LED1);
}

/*
 *  ======== mainThread ========
 */
void *mainThread(void *arg0)
{
    /* Call driver init functions */
    GPIO_init();

    /* Configure the LED pins */
    GPIO_setConfig(Board_GPIO_LED0, GPIO_CFG_OUT_STD | GPIO_CFG_OUT_LOW);
    GPIO_setConfig(Board_GPIO_LED1, GPIO_CFG_OUT_STD | GPIO_CFG_OUT_LOW);

    /* Configure the Button pins */
    GPIO_setConfig(Board_GPIO_BUTTON0, GPIO_CFG_IN_PU | GPIO_CFG_IN_INT_FALLING);
    GPIO_setConfig(Board_GPIO_BUTTON1, GPIO_CFG_IN_PU | GPIO_CFG_IN_INT_FALLING);

    /* Turn on user LEDs */
    GPIO_write(Board_GPIO_LED0, Board_GPIO_LED_ON);
    GPIO_write(Board_GPIO_LED1, Board_GPIO_LED_ON);

    /* install Button callback */
    GPIO_setCallback(Board_GPIO_BUTTON0, gpioButtonFxn0);
    GPIO_setCallback(Board_GPIO_BUTTON1, gpioButtonFxn1);

    /* Enable interrupts */
    GPIO_enableInt(Board_GPIO_BUTTON0);
    GPIO_enableInt(Board_GPIO_BUTTON1);
}

最终实现效果如下
