本文主要是介绍CC1310 SimpleLink SDK PIN/GPIO的使用，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
1.声明配置并初始化PIN
在“CC1310_LAUNCHXL.h”文件中预定义
#define CC1310_LAUNCHXL_PIN_BEEP IOID_3
#define CC1310_LAUNCHXL_PIN_RS485_TEN IOID_0
#define CC1310_LAUNCHXL_PIN_SYSLED IOID_9
#define CC1310_LAUNCHXL_PIN_ALMLED IOID_8
/* UART Board */
#define CC1310_LAUNCHXL_UART_RX IOID_1 /* RXD */
#define CC1310_LAUNCHXL_UART_TX IOID_2 /* TXD */在文件“CC1310_LAUNCHXL.c”中配置如下：
const PIN_Config BoardGpioInitTable[] = {CC1310_LAUNCHXL_PIN_RS485_TEN | PIN_GPIO_OUTPUT_EN | PIN_GPIO_LOW | PIN_PUSHPULL | PIN_DRVSTR_MAX, /* LOW RECEIVE */CC1310_LAUNCHXL_PIN_BEEP | PIN_GPIO_OUTPUT_EN | PIN_GPIO_LOW | PIN_PUSHPULL | PIN_DRVSTR_MAX, /* LOW OFF */ CC1310_LAUNCHXL_PIN_SYSLED | PIN_GPIO_OUTPUT_EN | PIN_GPIO_HIGH | PIN_PUSHPULL | PIN_DRVSTR_MAX, /* HIGH OFF */CC1310_LAUNCHXL_PIN_ALMLED | PIN_GPIO_OUTPUT_EN | PIN_GPIO_HIGH | PIN_PUSHPULL | PIN_DRVSTR_MAX, /* HIGH OFF */CC1310_LAUNCHXL_UART_RX | PIN_INPUT_EN | PIN_PULLDOWN, /* UART RX via debugger back channel */CC1310_LAUNCHXL_UART_TX | PIN_GPIO_OUTPUT_EN | PIN_GPIO_LOW | PIN_PUSHPULL, /* UART TX via debugger back channel */PIN_TERMINATE
};初始化PIN如下：#include <ti/drivers/PIN.h>
void CC1310_LAUNCHXL_initGeneral(void)
{Power_init();if (PIN_init(BoardGpioInitTable) != PIN_SUCCESS) {/* Error with PIN_init */while (1);}/* Perform board-specific initialization *///Board_initHook();
}PIN初始化后，我们已经可以使用driver/PIN.h文件中提供的API使用这些引脚了，如果我们想要直接使用某些引脚实现IO功能的话可以直接调用PIN_open()函数，但是在有操作系统的应用程序中并不推荐这样做，因为这并非线程安全的。上面PIN_init函数会将我们需要的引脚配置为GPIO可用的状态，但是在想使用这些引脚作为GPIO之前，还需要完成GPIO外设的初始化。
2.声明配置并初始化GPIO
#include <ti/drivers/GPIO.h>
在“CC1310_LAUNCHXL.c”文件中
/** =============================== GPIO ===============================*/
#include <ti/drivers/GPIO.h>
#include <ti/drivers/gpio/GPIOCC26XX.h>/** Array of Pin configurations* NOTE: The order of the pin configurations must coincide with what was* defined in CC1310_LAUNCHXL.h* NOTE: Pins not used for interrupts should be placed at the end of the* array. Callback entries can be omitted from callbacks array to* reduce memory usage.*/
GPIO_PinConfig gpioPinConfigs[] = {GPIOCC26XX_DIO_00 | GPIO_CFG_OUT_STD | GPIO_CFG_OUT_HIGH, /* RS485 设置默认高则为发送状态 */GPIOCC26XX_DIO_01 | GPIO_DO_NOT_CONFIG, /* UART RX */GPIOCC26XX_DIO_02 | GPIO_DO_NOT_CONFIG, /* UART TX */GPIOCC26XX_DIO_03 | GPIO_CFG_OUT_STD | GPIO_CFG_OUT_LOW, /* BEEP 默认不发声音*/GPIOCC26XX_DIO_07 | GPIO_DO_NOT_CONFIG, /* NO USE */GPIOCC26XX_DIO_06 | GPIO_DO_NOT_CONFIG, /* NO USE */GPIOCC26XX_DIO_04 | GPIO_DO_NOT_CONFIG, /* NO USE */GPIOCC26XX_DIO_05 | GPIO_DO_NOT_CONFIG, /* NO USE *//* ALARM LED 默认不亮*/GPIOCC26XX_DIO_08 | GPIO_CFG_OUT_STD | GPIO_CFG_OUT_HIGH, /* SYS LED 默认不亮*/GPIOCC26XX_DIO_09 | GPIO_CFG_OUT_STD | GPIO_CFG_OUT_HIGH,
};/** Array of callback function pointers* NOTE: The order of the pin configurations must coincide with what was* defined in CC1310_LAUNCH.h* NOTE: Pins not used for interrupts can be omitted from callbacks array to* reduce memory usage (if placed at end of gpioPinConfigs array).*/
GPIO_CallbackFxn gpioCallbackFunctions[] = {NULL, /* */NULL, /* */NULL, /* */NULL, /* */
};const GPIOCC26XX_Config GPIOCC26XX_config = {.pinConfigs = (GPIO_PinConfig *)gpioPinConfigs,.callbacks = (GPIO_CallbackFxn *)gpioCallbackFunctions,.numberOfPinConfigs = CC1310_LAUNCHXL_GPIOCOUNT,.numberOfCallbacks = sizeof(gpioCallbackFunctions)/sizeof(GPIO_CallbackFxn),.intPriority = (~0)
};以上 GPIOCC26XX_DIO_?? 其实就是 IOID_? ， 在“ti\drivers\gpio\GPIOCC26XX.h”文件中有声明如下：
#define GPIOCC26XX_DIO_00 IOID_0 /*!< @hideinitializer */
#define GPIOCC26XX_DIO_01 IOID_1 /*!< @hideinitializer */
#define GPIOCC26XX_DIO_02 IOID_2 /*!< @hideinitializer */
#define GPIOCC26XX_DIO_03 IOID_3 /*!< @hideinitializer */
#define GPIOCC26XX_DIO_04 IOID_4 /*!< @hideinitializer */
#define GPIOCC26XX_DIO_05 IOID_5 /*!< @hideinitializer */
#define GPIOCC26XX_DIO_06 IOID_6 /*!< @hideinitializer */
#define GPIOCC26XX_DIO_07 IOID_7 /*!< @hideinitializer */在“CC1310_LAUNCHXL.h”文件中声明GPIOName，注意这个声明的顺序必须与以上“”文件中gpioPinConfigs声明一样。
/*!* @def CC1310_LAUNCHXL_GPIOName* @brief Enum of GPIO names*/
typedef enum CC1310_LAUNCHXL_GPIOName {CC1310_RS485_EN = 0, //485CC1310_LAUNCHXL_GPIO_S2,CC1310_LAUNCHXL_SPI_MASTER_READY,CC1310_BEEP,CC1310_LAUNCHXL_GPIO_LED_GREEN,CC1310_LAUNCHXL_GPIO_LED_RED,CC1310_LAUNCHXL_GPIO_TMP116_EN,CC1310_LAUNCHXL_GPIO_SPI_FLASH_CS,CC1310_ALMLED,CC1310_SYSLED,CC1310_LAUNCHXL_GPIOCOUNT
} CC1310_LAUNCHXL_GPIOName;
3.GPIO的使用
头文件：
#include <ti/drivers/GPIO.h>使用前调用GPIO_init();
API调用：
GPIO_write(uint_least8_t index, unsigned int value);
uint_fast8_t GPIO_read(uint_least8_t index);
void GPIO_toggle(uint_least8_t index);例子：
GPIO_write(CC1310_LAUNCHXL_BEEP , 1); //测试发声
GPIO_write(CC1310_LAUNCHXL_SYSLED, 1); //测试 信号接收指示
GPIO_write(CC1310_LAUNCHXL_ALMLED, 1); //测试 4G转发指示
Task_sleep( 100000 / Clock_tickPeriod );
GPIO_toggle(CC1310_LAUNCHXL_BEEP); //测试发声
GPIO_toggle(CC1310_LAUNCHXL_SYSLED); //测试
GPIO_toggle(CC1310_LAUNCHXL_ALMLED); //测试对于CC1310，TI论坛上建议选用PIN系列的驱动。
The GPIO driver is supported for all device families except CC26xx/CC13xx. For the CC26xx/CC13xx device family, the PIN driver should be used. There is a GPIO driver for the CC26xx/CC13xx family within the driver product, however it is not promoted nor supported for external customer use.
