##SD-CARD Version with configuation text file##
receiving WiFi data from Binance API/Websocket_v3
This will show a 24 candles, the min/max price and the volume as line, date and time are from time.nist.gov timeserver. For M5-Stack MCU , coded in ArduinoIDE 1.8.13 - last modified Nov.20.2021 15:20 CET - Version 1.0.53fix - using spiffs + SDconfig (https://github.com/frittna/Crypto_Coin_Ticker)
LAST (small) EDITS:
-added cycling function (ButtonA+ButtonC together) which steps through your currencies after a certain time (default:off; when on - default:15sec for each)
-added Timezone for Singapore (UTC+8)
-code merged to one version, so there is no need to have different versions anymore
-autodetect the built in SHT room sensor and adds a 12pixel high sensor panel when the M5Stack is in its vertical BTC stand (original grey holder)
-temperature unit C or F and offset can be set by SD-Config and is not hard-coded anymore (because the M5-Stack is heating up itself it will never be accurate and has only limited expressiveness..)
> do not forget to update your sdconfig.cfg on SD-card too <
##Using the App:- This version needs a SD-Card (at least on first load) with your WiFi credentials, favourite coinpairs, timezone and language (eng/ger/esp) etc. in a textfile - see instructions
- ButtonA: switches through your favourite coinpairs (as many you want) e.g: BTC/USDT or LINK/BNB etc. which are available on Binance.com's spot maket.
- 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->...or vice versa
- available timeframes are 1minute, 3m, 5m, 15m, 1h, 4h, 1d, 1w, 1Month
- if you hold ButtonC at Startup: it will start with alternative SSID2/WiFi-password2 instead (e.g your mobile phone's hotspot)
- press ButtonA and ButtonC together to enable/disable automatic cycling through all currencies after a set time (default: off, when turned on default: 15sec)
- The top infoPanel shows WiFi-strength, batterylevel, colored indicators for "busy", SleepTimer on, price moving and if it is charging from usb (can have delay up to 30s)
- right now: english, german, spanish (for day and month names)
- SleepTimer: when holding ButtonB longer than 1, 5 seconds it will start a user defined timer to powerOFF the device (45min default)
- 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 (ver. 0.5.2 tested only)
- 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)
- All settings will remain stored in internal memory after a reset so you can eject the SD-Card after setting up you favourites.
- If you want to clear all stored settings from internal memory hold ButtonB at start-up
- If M5-Stack is in his BTC stand (the original grey vertical stand) the internal SHT room sensor is found and shows temp and humidity in degree F or C.
--> SEE CODE OR READMEs FOR INSTRUCTION IF YOU'RE NOT SURE <--
todos: e.g: alerts, more use of lights (sounds), wireless configuration method, a better prizeformatting with very low or very high prices (e.g. theres a "problem" when btc goes past 100k ;) ....etc. (my Problem: lack of time and coding knowledge)
