For the K22, is ADC0_DM3 connected to any of single ended inputs of ADC0?

[la_dsp]

In a previous post (ADC_LDD for Kinetis K10 ), it was mentioned that it was not connected for the K10 and there was an error in the hardware/manual.

Does this error also exist for the K22?

I feel like an error does exist as I am able to sample other channels on my K22, but not AD21 (which should be connected to ADC0_DM3).

Thanks.

Hi Alice,

I am using the MK22FX512VLH12.

Thank you.

Hi Angelo,

I have test  on it, in my result , when   use ADC0_DM3 pin,  ADC0 - AD21 channel  and single mode ,  can't get data;

And my colleague  Hui_Ma verify it can use as  differential mode .

Best Regards!

Alice

Hi Angelo,

ADC0_DM3 pin can only be used as differential mode, not work at single-ended mode.

The K22 reference manual with error info. Sorry for that may bring any inconvenience to you.

Wish it helps.
best regards
Ma Hui

Hi

Can you please confirm the differential ADC pins that can be used in single-ended mode??

I'm also using the MK22FX512VLXX mcu.

The following are the differential ADC pins on the 100pin LQFP package.

pin 21 - ADC1_DM0/ADC0_DM3

pin 20 - ADC1_DM0/ADC0_DP3

pin 19 - ADC0_DM0/ADC1_DM3

pin 18 - ADC0_DP0/ADC1_DP3

pin 17 - ADC1_DM1

pin 16 - ADC1_DP1

pin 15 - ADC0_DM1

pin 14 - ADC0_DP1

i currently have signals assigned to pins 20, 18, 15 & 14.

Will these pins work in single ended mode?

Regards

Jerome
