以下是使用STM32F103C8T6点亮LED的示例代码:
```c
#include "stm32f10x.h"
#include "stm32f10x_gpio.h"
#include "stm32f10x_rcc.h"
int main(void)
{
// 使能GPIOC外设时钟
RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOC, ENABLE);
// 初始化GPIOC为推挽输出模式
GPIO_InitTypeDef GPIO_InitStructure;
GPIO_InitStructure.GPIO_Pin = GPIO_Pin_13;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_Out_PP;
GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
GPIO_Init(GPIOC, &GPIO_InitStructure);
// 点亮LED
GPIO_ResetBits(GPIOC, GPIO_Pin_13);
while(1)
{
// 循环等待
}
}
```
该代码将PC13引脚配置为推挽输出模式,并在该引脚上输出低电平,从而点亮连接到该引脚上的LED。如果需要控制LED的亮灭,可以通过改变引脚输出电平的方式实现。

Sure, to light up an LED using STM32F103C8T6, you need to connect the LED to a GPIO pin of the microcontroller and set the pin to output mode. Then, you can simply toggle the pin high and low to turn the LED on and off. Here's a sample code to do that:
```
#include "stm32f10x.h"
int main(void)
{
// Enable GPIOC peripheral clock
RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOC, ENABLE);
// Configure GPIOC Pin 13 as output push-pull
GPIO_InitTypeDef GPIO_InitStructure;
GPIO_InitStructure.GPIO_Pin = GPIO_Pin_13;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_Out_PP;
GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
GPIO_Init(GPIOC, &GPIO_InitStructure);
// Toggle LED on and off
while(1)
{
GPIO_WriteBit(GPIOC, GPIO_Pin_13, Bit_SET);
Delay(1000);
GPIO_WriteBit(GPIOC, GPIO_Pin_13, Bit_RESET);
Delay(1000);
}
}
```
Note: This is just a sample code and you may need to modify it according to your specific requirements.

下面是使用STM32F103C8T6点亮板载LED的代码,该板载LED连接在PA5引脚上:
```c
#include "stm32f10x.h" // 包含STM32F10x系列单片机的头文件
int main(void)
{
GPIO_InitTypeDef GPIO_InitStructure;
RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA, ENABLE); // 使能GPIOA时钟
GPIO_InitStructure.GPIO_Pin = GPIO_Pin_5; // 选择要控制的引脚
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_Out_PP; // 设置引脚为推挽输出
GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz; // 设置引脚输出速率为50MHz
GPIO_Init(GPIOA, &GPIO_InitStructure); // 初始化GPIOA
while(1)
{
GPIO_SetBits(GPIOA, GPIO_Pin_5); // 点亮LED
for(int i=0; i<1000000; i++); // 延时一段时间
GPIO_ResetBits(GPIOA, GPIO_Pin_5); // 熄灭LED
for(int i=0; i<1000000; i++); // 延时一段时间
}
}
```
上述代码将GPIOA的第5个引脚(PA5)设置为推挽输出,然后不停地点亮和熄灭板载LED。您可以根据需要更改GPIO引脚的配置和延时时间。
