Hi 

I Want to use , End of Conversion interrupt in ADC0 but when i set the NSTART bit in ADC0- MCR register in debug mode i saw in SFR view  ,ADC0_ISR EOC bit is set but the interrupt is not work.

when i use while for this bit in my function i Read the ADC Correctly .

i Attach my code here if my code have problem please let me now.

thanks

With Best Regards

Hello Vanima ,

Sorry for the late answer.

Did you solve your issue ?

I will check your source code with ADC Experts to determine why the interrupt is not handled.

         Best Regards

Hello Vanima ,

For your source code coming from B54L5 you have forgotten to set the IMR. The Interrupt Mask Register (IMR) contains the interrupt enable bits for the ADC.

uint32_t ADC_Start_Conversion(

void

) {
uint32_t Result;
ADC_0.CIMR0.B.CIM0 = 1;
ADC_0.IMR.R = 3;
ADC_0.MCR.B.NSTART = 1;

After updating ADC_Start_Conversion , you can receive the EOC Interrupt. Best regards Erwan
