STM32的RT-Thread PIN系統中 KEIL warning: #1296-D: extended constant initialiser used 處理方法

原創 wakojosin 2020-05-22 22:47

Keil編譯時產生告警：

warning: #1296-D: extended constant initialiser used

解決方法之一是改成如下就可以：

#define __STM32_PORT(port)  GPIO##port##_BASE

#define GET_PIN(PORTx,PIN) (rt_base_t)((16 * ( ((rt_base_t)__STM32_PORT(PORTx) - (rt_base_t)GPIOA_BASE)/(0x0400UL) )) + PIN)
