12-bit ADC Resolution for K3NG Rotator Controller
Posted: Sun Jun 28, 2020 12:45 pm
Hi all
The K3NG Rotator Controller project is aimed towards Arduino Mega 2560 or similar hardware.
Standard ADC resolution on many of the Arduino boards is 10-bit, however the Arduino Due, Zero, and MKR family and Teensy 3.x family have 12-bit ADCs.
So if you’re running this hardware (I'm using a Teensy 3.2), why not make use of the extra ADC resolution with four easy steps;
1 – Change rotator_features.h
2 – Change k3ng_rotator_controller.ino
3 – Recompile and upload to your target MCU
4 – Recalibrate your analogue sensors
