Posted on April 16, 2013 at 14:18Hi,
I found a problem while writing to the EEPROM. The uC type is STM8af6289. This part of the program is the folowing:
initializing part:
void FLASH_Config(void)
{
FLASH_SetProgrammingTime(FLASH_PROGRAMTIME_STANDARD);
FLASH_Unlock(FLASH_MEMTYPE_DATA);
while (FLASH_GetFlagStatus(FLASH_FLAG_DUL) == RESET);
}
main part program:
int main()
{
FLASH_Config();
while(1)
{
if(FLASH_GetFlagStatus(FLASH_FLAG_EOP)==RESET)
{
*(PointerAttr uint8_t*) (uint16_t)0x4001 = 0x55;
}
GPIO_WriteReverse(LED2_GPIO_PORT, LED2_GPIO_PINS);
}
}
As it says, I should see on the oscilloscope a signal with 1-2 us timing. But I can see a square wave signal having about 50% duty cicle and the timing is about 10 ms.
Do anyone have an idea what should I do? Thank you for your help.
