I recently got the following error when i externally added stm8_interrupt_vector.c to my project source. Creating a project in STVD with raisonance complier selected did not generate any interrupt_vector.c file for me so i decided to add that file that was previously generated by creating project with cosmic selected. For the time being i decided to use raisonance instead of cosmic because i have to wait after requesting a file.

#include "stm8s_it.h"
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;
}

Anyway on above lines of stm8_interrupt_vector.c i get the following error

Hi,

Your problem is that you did not read the compiler documentation ;^)

The mechanism used by the Cosmic compiler is very different than ours.
With the Raisonance toolchain, you just have to add "interrupt N" after a function declaration, such as:

void UART_IRQ_Handler(void) interrupt 12
{
    ...
}

And that IT! The compiler/linker will automatically take care of your interrupts, create the vectors for them and locate them at the right place in memory.

2 suggestions though:
- Consider using Ride7 instead of STVD, as the toolset integration is better.
- Declare your main function with "void main(void)" and place a "while(1);" at its end.

Regards,
