帮我写一个stm32的led闪烁程序，用状态机实现，有8个led灯，每个led灯两种颜色

STM32 LED 闪烁程序（状态机实现）：

#include "stm32f10x.h"

#define LED1_ON() GPIOA->BSRR = 1<<8
#define LED1_OFF() GPIOA->BRR = 1<<8
#define LED2_ON() GPIOA->BSRR = 1<<9
#define LED2_OFF() GPIOA->BRR = 1<<9
#define LED3_ON() GPIOA->BSRR = 1<<10
#define LED3_OFF() GPIOA->BRR = 1<<10
#define LED4_ON() GPIOA->BSRR = 1<<11
#define LED4_OFF() GPIOA->BRR = 1<<11
#define LED5_ON() GPIOB->BSRR = 1<<12
#define LED5_OFF() GPIOB->BRR = 1<<12
#define LED6_ON() GPIOB->BSRR = 1<<13
#define LED6_OFF() GPIOB->BRR = 1<<13
#define LED7_ON() GPIOB->BSRR = 1<<14
#define LED7_OFF() GPIOB->BRR = 1<<14
#define LED8_ON() GPIOB->BSRR = 1<<15
#define LED8_OFF() GPIOB->BRR = 1<<15
