相信很多朋友在STM8的开发中很多是使用官方的固件库来进行开发的，这样开发速度快，并且程序不易出错。

前面的博客讲到了如何在STVD中新建一个新的STM8L151的工程，最后新建成功后，出现下面的工程目录：

在STM8_interrupt_vector.c 文件中，代码如下：

[cpp] view plain copy

/* BASIC INTERRUPT VECTOR TABLE FOR STM8 devices
* Copyright (c) 2007 STMicroelectronics
*/
typedef void @far (*interrupt_handler_t)(void);
struct interrupt_vector {
unsigned char interrupt_instruction;
interrupt_handler_t interrupt_handler;
};
@far @interrupt void NonHandledInterrupt (void)
{
/* in order to detect unexpected events during development,
it is recommended to set a breakpoint on the following instruction
*/
return;
}
extern void _stext(); /* startup routine */
struct interrupt_vector const _vectab[] = {
{0x82, (interrupt_handler_t)_stext}, /* reset */
{0x82, NonHandledInterrupt}, /* trap */
{0x82, NonHandledInterrupt}, /* irq0 */
{0x82, NonHandledInterrupt}, /* irq1 */
{0x82, NonHandledInterrupt}, /* irq2 */
{0x82, NonHandledInterrupt}, /* irq3 */
{0x82, NonHandledInterrupt}, /* irq4 */
{0x82, NonHandledInterrupt}, /* irq5 */
{0x82, NonHandledInterrupt}, /* irq6 */
{0x82, NonHandledInterrupt}, /* irq7 */
{0x82, NonHandledInterrupt}, /* irq8 */
{0x82, NonHandledInterrupt}, /* irq9 */
{0x82, NonHandledInterrupt}, /* irq10 */
{0x82, NonHandledInterrupt}, /* irq11 */
{0x82, NonHandledInterrupt}, /* irq12 */
{0x82, NonHandledInterrupt}, /* irq13 */
{0x82, NonHandledInterrupt}, /* irq14 */
{0x82, NonHandledInterrupt}, /* irq15 */
{0x82, NonHandledInterrupt}, /* irq16 */
{0x82, NonHandledInterrupt}, /* irq17 */
{0x82, NonHandledInterrupt}, /* irq18 */
{0x82, NonHandledInterrupt}, /* irq19 */
{0x82, NonHandledInterrupt}, /* irq20 */
{0x82, NonHandledInterrupt}, /* irq21 */
{0x82, NonHandledInterrupt}, /* irq22 */
{0x82, NonHandledInterrupt}, /* irq23 */
{0x82, NonHandledInterrupt}, /* irq24 */
{0x82, NonHandledInterrupt}, /* irq25 */
{0x82, NonHandledInterrupt}, /* irq26 */
{0x82, NonHandledInterrupt}, /* irq27 */
{0x82, NonHandledInterrupt}, /* irq28 */
{0x82, NonHandledInterrupt}, /* irq29 */
};

代码中的中断向量表需要我们自己修改，至于如何修改在STM8L151的官方固件库里有，下面看一下官方固件库里的stm8_interrupt_vector.c文件，代码如下：

[cpp] view plain copy

/* BASIC INTERRUPT VECTOR TABLE FOR STM8 devices
*/
#include "stm8l15x_it.h"
typedef void @far (*interrupt_handler_t)(void);
struct interrupt_vector {
uint8_t interrupt_instruction;
interrupt_handler_t interrupt_handler;
};
struct interrupt_vector const _vectab[] = {
{0x82, (interrupt_handler_t)_stext}, /* Reset */
{0x82, (interrupt_handler_t)TRAP_IRQHandler}, /* TRAP - Software interrupt */
{0x82, (interrupt_handler_t)NonHandledInterrupt}, /* Reserved */
{0x82, (interrupt_handler_t)FLASH_IRQHandler}, /* irq1 - FLASH interrupt */
{0x82, (interrupt_handler_t)DMA1_CHANNEL0_1_IRQHandler}, /* irq2 - DMA1 channel0 and channel1 interrupt */
{0x82, (interrupt_handler_t)DMA1_CHANNEL2_3_IRQHandler}, /* irq3 - DMA1 channel2 and channel3 interrupt */
{0x82, (interrupt_handler_t)RTC_CSSLSE_IRQHandler}, /* irq4 - RTC/ CSS on LSE interrupt */
{0x82, (interrupt_handler_t)EXTIE_F_PVD_IRQHandler}, /* irq5 - External IT PORTE/F interrupt /PVD interrupt*/
{0x82, (interrupt_handler_t)EXTIB_G_IRQHandler}, /* irq6 - External IT PORTB / PORTG interrupt */
{0x82, (interrupt_handler_t)EXTID_H_IRQHandler}, /* irq7 - External IT PORTD / PORTH interrupt */
{0x82, (interrupt_handler_t)EXTI0_IRQHandler}, /* irq8 - External IT PIN0 interrupt */
{0x82, (interrupt_handler_t)EXTI1_IRQHandler}, /* irq9 - External IT PIN1 interrupt */
{0x82, (interrupt_handler_t)EXTI2_IRQHandler}, /* irq10 - External IT PIN2 interrupt */
{0x82, (interrupt_handler_t)EXTI3_IRQHandler}, /* irq11 - External IT PIN3 interrupt */
{0x82, (interrupt_handler_t)EXTI4_IRQHandler}, /* irq12 - External IT PIN4 interrupt */
{0x82, (interrupt_handler_t)EXTI5_IRQHandler}, /* irq13 - External IT PIN5 interrupt */
{0x82, (interrupt_handler_t)EXTI6_IRQHandler}, /* irq14 - External IT PIN6 interrupt */
{0x82, (interrupt_handler_t)EXTI7_IRQHandler}, /* irq15 - External IT PIN7 interrupt */
{0x82, (interrupt_handler_t)LCD_AES_IRQHandler}, /* irq16 - LCD / AES interrupt */
{0x82, (interrupt_handler_t)SWITCH_CSS_BREAK_DAC_IRQHandler}, /* irq17 - CLK switch/CSS interrupt/ TIM1 Break interrupt / DAC */
{0x82, (interrupt_handler_t)ADC1_COMP_IRQHandler}, /* irq18 - ADC1 and Comparator interrupt */
{0x82, (interrupt_handler_t)TIM2_UPD_OVF_TRG_BRK_USART2_TX_IRQHandler}, /* irq19 - TIM2 Update/Overflow/Trigger/Break / USART2 TX interrupt */
{0x82, (interrupt_handler_t)TIM2_CC_USART2_RX_IRQHandler}, /* irq20 - TIM2 Capture/Compare / USART2 RX interrupt */
{0x82, (interrupt_handler_t)TIM3_UPD_OVF_TRG_BRK_USART3_TX_IRQHandler}, /* irq21 - TIM3 Update/Overflow/Trigger/Break / USART3 TX interrupt */
{0x82, (interrupt_handler_t)TIM3_CC_USART3_RX_IRQHandler}, /* irq22 - TIM3 Capture/Compare /USART3 RX interrupt */
{0x82, (interrupt_handler_t)TIM1_UPD_OVF_TRG_COM_IRQHandler}, /* irq23 - TIM1 Update/Overflow/Trigger/Commutation interrupt */
{0x82, (interrupt_handler_t)TIM1_CC_IRQHandler}, /* irq24 - TIM1 Capture/Compare interrupt */
{0x82, (interrupt_handler_t)TIM4_UPD_OVF_TRG_IRQHandler}, /* irq25 - TIM4 Update/Overflow/Trigger interrupt */
{0x82, (interrupt_handler_t)SPI1_IRQHandler}, /* irq26 - SPI1 interrupt */
{0x82, (interrupt_handler_t)USART1_TX_TIM5_UPD_OVF_TRG_BRK_IRQHandler}, /* irq27 - USART1 TX / TIM5 Update/Overflow/Trigger/Break interrupt */
{0x82, (interrupt_handler_t)USART1_RX_TIM5_CC_IRQHandler}, /* irq28 - USART1 RX / TIM1 Capture/Compare interrupt */
{0x82, (interrupt_handler_t)I2C1_SPI2_IRQHandler}, /* irq29 - I2C1 / SPI2 interrupt */
};

直接将这个文件替换原来的文件即可。
另外需要将固件库里的libraries的inc、src文件夹的文件放到工程里面。还有stm8l15x_conf.h、stm8l15x_it.c、stm8l15x_it.h放到工程里。并配置stm8l15x_conf.h里的MCU选择，最后的工程文件架构大概如下：

到这里，就可以使用官方的固件库来进行开发了。
