Internal Vref for ADC in MK10

[ssarathkumar916]

Hi,

We are using MK10DX256xxx7 controllers. and We use Rowley cross works IDE for programming. 

We want to use 1.2V Internal VREF for ADC.

As per datasheet,we tried setting ADC_SC2->REFSEL 

and VREF_SC->VREFEN

we probed VREF_OUT pin using Oscilloscope, but  no voltage got generated. 

Please guide us to generate internal 1.2V VREF.

Please share any code or schematics for reference.

Thanks,

Sarathkumar S

Hello ‌

I suggest you to leave the bit REFSEL of the register ADC_SC2 as 0x01.

For the VREF status a control register please set 0x01 at the following bits: VREFEN, REGEN, ICOMPEN and MODE_LV.

Please let me know if this is helpful.

Best regards,

Omar
