# 执行AI 测试固件模板

## C语言测试固件示例

```c
#include <stdint.h>
#include <stdio.h>

#define LED_PIN 13

void delay(volatile uint32_t count) {
    while (count--);
}

int main(void) {
    // 初始化 GPIO
    GPIO_Init();
    
    printf("MCU芯片测试开始\n");
    
    while (1) {
        // LED 闪烁
        GPIO_Toggle(LED_PIN);
        printf("LED Toggle\n");
        delay(1000000);
    }
}
```

## 编译配置 (Makefile)

```makefile
CC = arm-none-eabi-gcc
CFLAGS = -mcpu=cortex-m7 -mthumb -O2
LDFLAGS = -T linker.ld
TARGET = firmware
SRC = main.c

all: $(TARGET).hex

$(TARGET).elf: $(SRC)
	$(CC) $(CFLAGS) $(LDFLAGS) $^ -o $@

$(TARGET).hex: $(TARGET).elf
	arm-none-eabi-objcopy -O ihex $< $@

clean:
	rm -f *.elf *.hex
```
