********************************************************************************
Advanced Tuner software for NXP TEF668x ESP32
(c) 2023 Sjef Verhoeven pe5pvb@het-bar.net & Noobish noobish@noobish.eu
Based on Catena / NXP semiconductors API
********************************************************************************
Analog signalmeter:
to meter
|
R V
IO27 -------=====-----=====---|
1 k 5 k POT
********************************************************************************
Setup:
During boot:
Hold BW button to change rotary encoder direction
Hold Mode button the flip screen
Hold Standby button to calibrate analogue s-meter
Hold rotary button to switch between normal and optical rotary encoder
Manual:
STANDBY SHORT PRESS: Switch band
STANDBY LONG PRESS: Standby
ROTARY SHORT PRESS: Set stepsize or navigate
ROTARY LONG PRESS: Toggle iMS & EQ
MODE SHORT PRESS: Switch between auto/manual
or exit menu
MODE LONG PRESS: Open menu
BW SHORT PRESS: Switch bandwidth setting
BW LONG PRESS: Switch mono, or auto stereo
* ***********************************************
ATTENTION: If you want to compile this code, use Arduino Core for ESP32 v1.0.6 - newer versions won't work!
* ***********************************************
Use these settings in TFT_eSPI User_Setup.h
