hal-led.h 下
我们可以配置多少个 LED 输出? 这就是我对8个 LED 输出所做的操作。
#define HAL_LED_1 0x01
#define HAL_LED_2 0x02
#define HAL_LED_3 0x04
#define HAL_LED_4 0x08
#define HAL_LED_5 0x10
#define HAL_LED_6 0x20
#define HAL_LED_7 0x40
#define HAL_LED_8 0x80
#define HAL_LED_ALL (HAL_LED_1 | HAL_LED_2 | HAL_LED_3 | HAL_LED_4 | HAL_LED_5 | HAL_LED_6 | HAL_LED_7 | HAL_LED_8)
如果我希望13个 LED 输出该怎么办呢。
它应该是什么样的?
(笑声)
#define HAL_LED_7 0x40
#define HAL_LED_8 0x80
#define HAL_LED_9 0x??
#define HAL_LED_10 0x??
#define HAL_LED_11 0x??
#define HAL_LED_12 0x??
#define HAL_LED_13 0x??
谢谢你
