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.
Solved! Go to Solution.
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

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!

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
