STM8的COSMIC8編譯器問題

只看该作者 · 2009-7-15 10:43

COSMIC手冊說：中斷函數必須用＠near修飾，但是生成的中斷文件里卻將向量定義成一個指向＠far的指針？？？？

以下是COSMIC手冊：
The STM8 architecture forces any interrupt function to be located in the
first 64K. The interrupt vector table containing 2-byte addresses, interrupt
functions declared in C must be declared with the @near modifier
if the vector table is also written in C.

以下是COSMIC自動生成的中斷文件：

/*    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 */
};

如題

COSMIC STM8现在最新的好像是4.2.10,在 < C Cross Compiler User’s Guide
for ST Microelectronics STM8 > 里没查到
"The STM8 architecture forces any interrupt function to be located in the first 64K. The interrupt vector table containing 2-byte addresses, interrupt functions declared in C must be declared with the @near modifier if the vector table is also written in C."

在STM8的reference manual里也不曾见过这种说法.

此外这个观点是错误的,STM8的中断完全可以定位到0x10000以后,你试一下就知道了.

名稱：CXSTM8_UsersGuide.pdf,安裝完編譯器后，版本4.2，弟57頁：write a interrupt hands. 見文檔。

我装的cosmic 也有这个文件,版本也是4.2,不过这一段已经被去掉了.建议你装个最新的版本吧.

你完全可以用如下方法做，不用考虑@far 或 @near。

#define NULL 0

extern void _stext();        /* startup routine */

void (* const @vector _vectab[32])() = {
    _stext,            /* RESET       */
    NULL,            /* TRAP        */
    NULL,            /* TLI         */
    NULL,            /* AWU         */
    NULL,            /* CLK         */
    NULL,            /* EXTI PORTA  */
    NULL,            /* EXTI PORTB  */
    NULL,            /* EXTI PORTC  */
    NULL,            /* EXTI PORTD  */
    NULL,            /* EXTI PORTE  */
    NULL,            /* CAN RX      */
    NULL,            /* CAN TX      */
    NULL,            /* SPI         */
    NULL,            /* TIMER 1 OVF */
    NULL,            /* TIMER 1 CAP */
    NULL,            /* TIMER 2 OVF */
    NULL,            /* TIMER 2 CAP */
    NULL,            /* TIMER 3 OVF */
    NULL,            /* TIMER 3 CAP */
    NULL,            /* USART TX    */
    NULL,            /* USART RX    */
    NULL,            /* I2C         */
    NULL,            /* LINUART TX  */
    NULL,            /* LINUART RX  */
    NULL,            /* ADC         */
    NULL,            /* TIMER 4 OVF */
    NULL,            /* EEPROM ECC  */
    NULL,            /* Reserved    */
    NULL,            /* Reserved    */
    NULL,            /* Reserved    */
    NULL,            /* Reserved    */
    NULL,            /* Reserved    */
    };
