CC1310: CC1310_LAUNCHXL_GPIOName与IOID的定义的区别

typedef enum CC1310_LAUNCHXL_GPIOName {
CC1310_LAUNCHXL_GPIO_S1 = 0,
CC1310_LAUNCHXL_GPIO_S2,
CC1310_LAUNCHXL_SPI_MASTER_READY,
CC1310_LAUNCHXL_SPI_SLAVE_READY,
CC1310_LAUNCHXL_GPIO_LED_GREEN,
CC1310_LAUNCHXL_GPIO_LED_RED,
CC1310_LAUNCHXL_GPIO_TMP116_EN,
CC1310_LAUNCHXL_GPIO_SPI_FLASH_CS,
CC1310_LAUNCHXL_SDSPI_CS,
CC1310_LAUNCHXL_GPIO_LCD_CS,
CC1310_LAUNCHXL_GPIO_LCD_POWER,
CC1310_LAUNCHXL_GPIO_LCD_ENABLE,
CC1310_LAUNCHXL_GPIOCOUNT
} CC1310_LAUNCHXL_GPIOName;

/* Discrete Inputs */
#define CC1310_LAUNCHXL_PIN_BTN1 IOID_13
#define CC1310_LAUNCHXL_PIN_BTN2 IOID_14

区别是啥，我直接用IOID的定义方式去设置Output可以正常工作，但是设置为input后就触发不了，原因未知

关系是枚举中的引脚配置顺序必须与CC1310_LAUNCHXL.c 中的GPIO配置数组保持一致：

*=============================== 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[] = {/* Input pins */GPIOCC26XX_DIO_13 | GPIO_DO_NOT_CONFIG,/* Button 0 */GPIOCC26XX_DIO_14 | GPIO_DO_NOT_CONFIG,/* Button 1 */GPIOCC26XX_DIO_15 | GPIO_DO_NOT_CONFIG,/* CC1310_LAUNCHXL_SPI_MASTER_READY */GPIOCC26XX_DIO_21 | GPIO_DO_NOT_CONFIG,/* CC1310_LAUNCHXL_SPI_SLAVE_READY *//* Output pins */GPIOCC26XX_DIO_07 | GPIO_DO_NOT_CONFIG,/* Green LED */GPIOCC26XX_DIO_06 | GPIO_DO_NOT_CONFIG,/* Red LED */GPIOCC26XX_DIO_30 | GPIO_DO_NOT_CONFIG,/* TMP116_EN *//* SPI Flash CSN */GPIOCC26XX_DIO_20 | GPIO_DO_NOT_CONFIG,/* SD CS */GPIOCC26XX_DIO_21 | GPIO_DO_NOT_CONFIG,/* Sharp Display - GPIO configurations will be done in the Display files */GPIOCC26XX_DIO_24 | GPIO_DO_NOT_CONFIG, /* SPI chip select */GPIOCC26XX_DIO_22 | GPIO_DO_NOT_CONFIG, /* LCD power control */GPIOCC26XX_DIO_23 | GPIO_DO_NOT_CONFIG, /*LCD enable */};

设置为input后就触发不了應該是你程序沒設置好

配置如下，帮忙看一下有啥问题

PIN_State asic_pinState; asic_pinHandle = PIN_open(&asic_pinState, asic_pinTable); if (asic_pinHandle == NULL) { while(1); }

PIN_Status status = PIN_registerIntCb(asic_pinHandle, &asic_int_handler);if (status != PIN_SUCCESS){while(1);}

void asic_int_handler(uint_least8_t index){ int_flag++;}

IOID_13| PIN_INPUT_EN | PIN_PULLUP | PIN_IRQ_NEGEDGE,

看起來沒有什麼問題，你直接用pininterrupt例程可以正確執行嗎？
