Help,can not enter into adc1 interrupt of stm8s105c4t6

Hello,Everyone:

The ADC Init is like this:

CLK_PCKENR2 |=0x08;

ADC_CSR = 0x05; //ch0~ch5

ADC_CR1 = 0x22; //f/4,CONT convertion

ADC_CR2 = 0x08; //ALIGN right,scan mode

//ADC_CR3 = 0x80; //enable data buff

ADC_TDRL = 0xff; //disable the smitt of ch0~ch7

ADC_CSR |= 0x20; //enable eoc int,

ADC_CR1 |=0x01; //start convertion

but the simulation using stlink can not enter into adc1 Interrupt handler,why? Can someone here help me, I'm using stvd4.12 and cosmic 16k verstion,thanks!

Hi Chris,

I think that you have missed to enable the general interrupt.

Can you verify that this line exist in your code: _asm(''rim\n'');

Thanks for your reply,but the reason is that i should set the adon bit twice,one for waking up,the other one for starting convertion.
