2020年03月17日 | STVD下STM8L151使用官方固件库开发

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：

/* 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：

/* BASIC INTERRUPT VECTOR TABLE FOR STM8 devices

 * Copyright (c) 2013 STMicroelectronics

 */

#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。
