I am currently working with the KL46Z mcu
and trying to use ADC with PE 10.4 and averaging enable.
When I enable averaging of 32 Samples per channel
my readings jump all over the place, but when setup for less than 32
my readings are OK.
The KL46Z is power from 5V using internal VREG
VREFH is tied to VDDA which is tied to VOUT33 from mcu.
VREFL is tied to VSSA which is tied to Board's GND (VSS1 to 4).
The ADC is setup for 12-Bit Resolution and 20us Conversion Time
Now if the averaging are set below 32 samples but ADC resolution is set for 16-Bit
the readings are jump around not as much as when 32 Aver setup but readings are
Has any body else experience similar issue?
