//****************************************
//* Dharma Counter for TTGO T-Display, *
//* with prostrations counting function. *
//* Version 1.0 *
//****************************************
//***********************************************************************************
//* Connections
//***********************************************************************************
// External buttons connected to GND and board pins:
// Pin 2 - [INC], [+] increment button
// Pin 27 - [DEC], [-] decrement button
// Pin 12 - [Audio], [Pause] button
// Build in buttons:
// Pin 0 - [NXT] next mode button
// Pin 35 - [PRV] previous mode button
// VL53L0X module for prostrations counter connected:
// SCL to pin 22 of board
// SDA to pin 21 of board
// Micro audio speaker (10mm) connected to:
// Pin 25 and GND
//***********************************************************************************
//* Functionality
//***********************************************************************************
// [INC] - increase current counter
// [DEC] - decrease current counter
// [DEC] long press - reset current counter
// [NXT] - next counter mode
// [PRV] - previous counter mode
// [Audio] - Sound ON/OFF and Pause in prostartions counter mode
// [NXT] long press or [PRV] long press - Configuration menu
//***********************************************************************************
//* Configuration menu
//***********************************************************************************
// The menu has minimal functionality. Most of the
// configuration is carried out through the web server in AP mode.
// [NXT] - next menu element
// [PRV] - previous menu element
// [INC] - select/increase value
// [DEC] - decrease value
//***********************************************************************************
//* Web server
//***********************************************************************************
// Web server in AP (Access Point) mode.
// After connecting to the Access Point via WiFi,
// use the IP address in the browser to open the configuration page.
// [INC] - show QR code for server IP
// [DEC] - exit from AP mode
//***********************************************************************************
// Application size about 1.8 Mb, so use partition scheme with 2 Mb for APP.
// All files from \data folder, must be uploaded to the SPIFFS.
// Use this tool: https://github.com/me-no-dev/arduino-esp32fs-plugin
