Keil uVision5点亮LED灯错误 距离点亮LED灯编程只有一步之遥了  还得请教各位老师问题在哪, 对着《STM32库开发实战指南》示例已经修改了几次错误，还是存在错误错误提示..STM_led.axf: Error: L6218E: Undefined symbol GPIO_RestBits (referred from main.o).直译：STM_led.axf：错误：L6218E：未定义符号GPIO_RestBits（从main.o引用）。 谢谢，回复，是GPIO_ResetBits(GPIOC,GPIO_Pin_3 )写错了GPIO_RestBits(GPIOC,GPIO_Pin_3 )少了个e,更改后问题又出来了：..STM_led.axf: Error: L6200E: Symbol GPIO_ResetBits multiply defined (by stm32f10x_gpio_1.o and stm32f10x_gpio.o).

LED1没有定义啊，不能直接用

有void LED1(参数);//声明
和void LED1(参数)//定义 { ……； } 这两个吗？有的话再看看有没有 extern void LED1(参数);//引用其他.c文件中的函数 |
