Hello.
I have a issue about saadc input range.
First, using 52832, SDK 15.3.0 S332 Softdevice.
I using ble ant both and 2 rtc time and gpiote also used.
my goal is measureing coin cell voltage.
coin cell is CR2032.
I success getting data. however max voltage is under 3.2V.
I use usb power.
under below is my Configure Setting.
under below is handler func.
using internal reference 0.6V and gain is 1/6. So I thought max voltage is 3.6V
But I Can't measure 3.2~3.6V.
I Changed ACQTIME . it was not work.
First screenshot is 3.1V. it works well.
Second screenshot is 3.3V. but the data is more lower.
Thank you.
