Would suggest your project is missing the GPIO source files.

 ,

 ,

Thanks for your reply clive !

But i have included GPIO header file too. I have written a program for an led to be in on state for a long and to be in off state for a short period. I am newer to this controller and the code i have written is below.

♯ include 'stm8s.h'

 ,

♯ include 'stm8s_gpio.h'

volatile void delay(volatile uint32_t t)

 ,

{

 ,

while(t--),

 ,

}

void main( void )

 ,

{

GPIO_DeInit(GPIOB),

 ,

GPIO_Init(GPIOB, GPIO_PIN_5, GPIO_MODE_OUT_PP_LOW_FAST),

 ,

GPIO_WriteHigh(GPIOB, GPIO_PIN_5),

 ,

delay(2000),

 ,

GPIO_WriteLow(GPIOB, GPIO_PIN_5),

 ,

delay(20000),

 ,

}

Can i know what is wrong in this program. Can you please help me out.

Include files provide prototypes, not function code.

Thanks for your reply, I know that it's basic thing. I have tried program in different manner so i ignored the previous program issues ad errors.
