stm8s103的time2定时中断官方bug（勘误手册没发现提到）

himan

调试stm8s103的定时器2中断，在stm8s208上OK的，到了stm8s103死活不能行。看了一下午对照参考手册看了一遍又一遍。看了寄存器，发现寄存器就是写不对。没道理写不对啊。查stm8s.h中关于time2的结构体，位置是对啊。以为被我修改了，下载一个替换掉还是不行。郁闷。后来想到iAR自带的库。一对比发现问题了。
typedef struct TIM2_struct
{
  __IO uint8_t CR1;   /*!< control register 1 */
  __IO uint8_t IER;   /*!< interrupt enable register */
  __IO uint8_t SR1;   /*!< status register 1 */
  __IO uint8_t SR2;   /*!< status register 2 */
  __IO uint8_t EGR;   /*!< event generation register */
  __IO uint8_t CCMR1; /*!< CC mode register 1 */
  __IO uint8_t CCMR2; /*!< CC mode register 2 */
  __IO uint8_t CCMR3; /*!< CC mode register 3 */
  __IO uint8_t CCER1; /*!< CC enable register 1 */
  __IO uint8_t CCER2; /*!< CC enable register 2 */
  __IO uint8_t CNTRH; /*!< counter high */
  __IO uint8_t CNTRL; /*!< counter low */
  __IO uint8_t PSCR;  /*!< prescaler register */
  __IO uint8_t ARRH;  /*!< auto-reload register high */
  __IO uint8_t ARRL;  /*!< auto-reload register low */
  __IO uint8_t CCR1H; /*!< capture/compare register 1 high */
  __IO uint8_t CCR1L; /*!< capture/compare register 1 low */
  __IO uint8_t CCR2H; /*!< capture/compare register 2 high */
  __IO uint8_t CCR2L; /*!< capture/compare register 2 low */
  __IO uint8_t CCR3H; /*!< capture/compare register 3 high */
  __IO uint8_t CCR3L; /*!< capture/compare register 3 low */
}
TIM2_TypeDef;
这是官方库的结构体
typedef struct TIM2_struct
{
  __IO uint8_t CR1;   /*!< control register 1 0*/
#if defined STM8S103
        __IO uint8_t RESERVED1; /*!< Reserved register */
        __IO uint8_t RESERVED2; /*!< Reserved register */
#endif
  __IO uint8_t IER;   /*!< interrupt enable register 1*/
  __IO uint8_t SR1;   /*!< status register 1 2*/
  __IO uint8_t SR2;   /*!< status register 2 3*/
  __IO uint8_t EGR;   /*!< event generation register 4*/
  __IO uint8_t CCMR1; /*!< CC mode register 1 5*/
  __IO uint8_t CCMR2; /*!< CC mode register 2 6*/
  __IO uint8_t CCMR3; /*!< CC mode register 3 7*/
  __IO uint8_t CCER1; /*!< CC enable register 1 8*/
  __IO uint8_t CCER2; /*!< CC enable register 2 9*/
  __IO uint8_t CNTRH; /*!< counter high a*/
  __IO uint8_t CNTRL; /*!< counter low b*/
  __IO uint8_t PSCR;  /*!< prescaler register c*/
  __IO uint8_t ARRH;  /*!< auto-reload register high d*/
  __IO uint8_t ARRL;  /*!< auto-reload register low e*/
  __IO uint8_t CCR1H; /*!< capture/compare register 1 high */
  __IO uint8_t CCR1L; /*!< capture/compare register 1 low */
  __IO uint8_t CCR2H; /*!< capture/compare register 2 high */
  __IO uint8_t CCR2L; /*!< capture/compare register 2 low */
  __IO uint8_t CCR3H; /*!< capture/compare register 3 high */
  __IO uint8_t CCR3L; /*!< capture/compare register 3 low */
}
TIM2_TypeDef;
这是IAR的结构体。
区别在红色字体上，IAR中多了两行。o(︶︿︶)o 唉

库过时了。

库过时了。

2.1的应该没过时把 从stmcu上面下载的呢

lixun00

2.0的无这个问题

lixun00

这种寄存器的头文件一般都是从厂家里拷贝过来的

apple_eat

bug依然存在

规格书里TIM2的描述:


TIM2_TypeDef里的寄存器地址从IER开始都偏移了2个位置.
