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

Hi Erwan

No the Problem is not Solved completly i should my MCU (SPC560B50L5) , i have bigger Problem the function's in this MCU completly different with (SPC560B54L5) , I saw a bug on the Function when i want to use the mcu Stop on the position and the mcu Halt.

if you can Help me on this or send me an application for this Chip thanks so much.

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
