Hi everyboy

Yess! I made good progress with my project, a Crypto Coin Price Ticker for monitoring crypto currencies on your desktop in a nice good looking and small device.

I have modified and enhanced some existing code i found to use with our great M5Stack Device (The CORE1 Version - with 3 buttons !) .
The original core of the code was from a github users project github.com/olbed/bitcoin-ticker
I ported it to M5, added many new features and now I want to share my resutls to all of you who wants a nice price ticker on your desktop to track your favorite crypto coins easily.

Get rid of your daily routine to turn on the PC or mobile phone for nothing important and only distracting stuff... Just see your loved Crypto and "forget" ! :)
edit: btw - look at this rise in btc from march 2020 to now on the picutures

read the info for the easy installation method or compile yourself

@op8 sorry for the late reply, thank you very much, i still love it to watch the price on it. The M5 core is the regular black framed M5-core and the bottom is the M5GO/FIRE Battery Bottom Charging Base SKU:A014 from this M5-Stack-Shop (do not forget to buy the chargning base plate as i did, these are 2 seperate items to buy) It has the rgb-led strip built-in but it is only barely used in my code.. My Intention was to show major price movements with red/green flashing lights (and sounds) for example. Unfortunately i did not implement additional functions since then.

Hi, really nice to explore your project! You have really gone thought all the steps which i skipped so far on my ticker. (mobile app to config, fw updates, multiple sources, webstore) NICE and very professional.

Updated Version (minor changings):

• added cycling function: enable/disable by pressing ButtonA+ButtonC together. steps through your currencies after a certain time (default: 15sec for each currency)

• added Timezone for Singapore (UTC+8)

• code merged to one version, so there is no need to have different versions anymore

• autodetect the optional room sensor and show 12pixel high sensor panel in this case temperature unit C or F and offset is set from SD-Config and not hardcoded anymore (because the M5-Stack is heating up itself it will never be accurate and has only limited expressiveness)

hard to predict but i experienced odd behavior with reading settings when i for example forgot to eject the sd-card on pc by control center (use checkdisk on the sd card too if you forgot).
Or maybe you have some hidden symbols from a copy paste action in your settings file or router config page. I'm not so good with ascii code but like when you see a url link with %20 for space or something. Maybe you used a complex texteditor? use simple text editor, no format options, and of course check every single sign... frustrating to not know. First i would try a fresh config file and only wifi settings. Before check your SD card. When this still fails try without space in name, if it works we have to accept that fact or better investigate that "space in name" problem of the used esp32 library

@jlp373 Hi! because of this problem i made a updated version two weeks ago. Sorry to not update it here.
Just visit https://github.com/frittna/Crypto_Coin_Ticker and download the zip archive (M5Burner_Crypto_Coin_Ticker.zip) for the easiest way.

the files SHTX3.ccp and SHTX3.h are normally in the root directory where you have the .ino file of the program (the sketch folder - ctrl+k loads it)
you see the structure on root directory on github aswell

because of the "#include" in the code it will show like this

.

regarding the compiler messages i quote myself:

btw: the one warning from "timezone" concerning a possible wrong architecture type while compiling the code is ok.. does not matter<

other messages in red about the SHT3X are ok too but not like your error, they will look like this picture and do not disturb compiling

i hope you have noticed that there is a very simple and short way to load the code without compiling in arduino at all .. right..? (M5Burner - "the simple way..") but i guess you know and want to modify something for your purpose

you have to follow the guide in the readme.txt if you want to compile it in arduino to modify something in the code.

download them all with Arduino -> library-manager - and watch for correct spelling and correct version numbers like in the readme given.

or if you dont want to change the code then take the easy way without any coding and load it into the m5-stack core1(!) not 2 - i think no one runs it on a core version 2 m5-stack units because there would be some changings needed with library versions and code (resets all time and won't start correct atm)

@yashax
is't not easy to adapt because i use a data stream direct from the binace exchange api with binace pairs only. Don't know if there is a similiar data stream for forex etc. candles that can be used in the same way (json format every 2 seconds with open, high, low, close and volume)

@dssguy1 said in Bitcoin / Multi Crypto Coin Ticker with 24 candlesticks chart:

Works perfect! THANKS!!! Now I can watch myself losing money again!

Nice to hear :) Well, Yes, like the frog methapher .. he would jump out instantly if he gets into too hot water to not get burnt but if he is sitting in cold water which rises in temperature slowly until it is cooking he will probably stay until he gets rekt. Who knows, nobody. Zero or moon or -98% - all is possible - have a really good plan (thats very hard to almost impossible if not investing tons of time) or have a position which you are comfortable with and dont do much

i uploaded a version that uses binance.us.
Use the M5Burner in my Zip File on Github

maybe it could be geo-blocked because here from the EU for example it still works normally!
please test:
https://api.binance.com/api/v3/depth?symbol=BTCUSDT&limit=1000
and
https://api.binance.us/api/v3/depth?symbol=BTCUSDT&limit=1000
If only the .us domain works for you i will update the code soon for an .us version.

If you compile it yourself with arduino you have to modify the .com to .us - so change these two lines:
const char restApiHost = "api.binance.us";
and
const char wsApiHost = "stream.binance.us";

@yashax
the white line is the relative trading volume from the last 24 shown candles

@yashax

you can check at line 500 in the code and simply change lines where is says "time(now)" to "timeFormat12(now)"
this will work and will show time in am/pm mode and not in 24h mode.
If you want to have a visualisation for am/pm too you would have to find free space first and draw something small with a the isAM() or isPM() function.

@yashax
yes, thats correct since prize data comes from the binance api only, spot markets, no derivates
