uj5u.com熱心網友回復：
stm32f10x_gpio.c 是否包含檔案？uj5u.com熱心網友回復：
uj5u.com熱心網友回復：
現在就是不明白提示的錯誤怎么來的，查網咯說是呼叫的東西定義問題，但看著該有的都有啊uj5u.com熱心網友回復：
需要包含函式宣告的.h 檔案，或者extern 也行，就是找不到函式定義了。uj5u.com熱心網友回復：
warning: #223-D: function "GPIO_ResetBits" declared implicitlyGPIO_ResetBits(GPIOC,GPIO_Pin_6);
宣告GPIO_ResetBits函式的的.h 檔案沒有include進來
uj5u.com熱心網友回復：
宣告GPIO_ResetBits函式的.h 檔案stm32f10x_gpio.h已經包含到main中；void GPIO_Setbits(GPIO_TypeDef *GPIOx,uint16_t GPIO_pin);
void GPIO_Resetbits(GPIO_TypeDef *GPIOx,uint16_t GPIO_pin);這兩句就是在stm32f10x_GPIO.h中 GPIO_ResetBits和GPIO_setBits定義
