##Using the App:

This version needs a SD-Card whith the your WiFi credentials, favourite coinpairs, timezone and language(eng/ger/esp) in a textfile - see installation
ButtonA: switches through your favourite Coinpair (as many you want) e.g: BTC/USDT etc. which are available on Binance.com
ButtonB: changes the LCD-Brightness in 4 levels
ButtonC: 9 changeable Timeframes from 1 Minute to 1 Month
turn OFF the device pressing the red button once OR by holding ButtonC for over 1 second if USB is connected
Press buttonC, then, within 2 sec press buttonA to switch down, or buttonB to switch up through the timeframes: 1min->15mins->1hour->..
available timeframes are 1minute, 3m, 5m, 15m, 1h, 4h, 1d, 1w, 1Month
if you hold ButtonC at Startup: it will start with alternative SSID/WiFi-password instead (e.g your mobile phone's hotspot)

##Further description:

The top infoPanel shows the WiFi-strength, batterylevel, colored indicators for "busy", SleepTimer, price moving and if charging from usb (can have delay up to 30s)
right now: english, german, spanish (day and month names)
SleepTimer: when holding ButtonB longer than 1,5 seconds it will start a user defined timer to powerOFF the device
If WiFi is failing more than 2 minutes it reduces the reconnect interval and brightness level, after 10 minutes -> shutdown device
SDMenu Loader compatible, if SD-Updater (menu.bin) is installed in your SD-card hold buttonA while booting up to start MenuLoader to load your apps
It is prepared for the use of a Neopixel RGB-LED bar (i use the built-in one in the Battery-Bottom Module for M5Stack/Fire with rgb 10 LEDs)
Some settings like current timeframe, brightness level, active coinpair and the last wifi credentials will remain stored in internal memory after a reset.
