Bitcoin / Multi Crypto Coin Ticker with 24 candlesticks chart

  • Hi,
    I figured it out by myself (so proud ;-) ) how to have BTC/€ displayed:

    byte pairs = 2; // default: 8, total numbers of currency pairs, max 255
    String pair_name[] = {"BTC/EUR", " BTC/$", }; //name for TopPanel (6-8 letters)
    String pair_STRING[] = {"BTCEUR", "BTCUSDT", }; //name for url in BIG LETTERS
    String pair_string[] = {"btceur", "btcusdt", }; //name for url in small letters
    uint32_t pair_color[] = {TFT_ORANGE, TFT_PINK, }; //color in uint32_t format

    Greetings Timo

  • thx!!
    Hi, yes you got it right. The name must be the same when you look at the part of the url accessing a usual binance market with your webborwser.

    But i wanted to mention that i have updated the App a bit more.
    There is no modification with Arduino in the code needed for adjusting the settings.
    Now you can easily burn the app with few clicks, no Arduino needed, if you don't want. You only need a config text file on the root of your sd-card from where settings are read in, then you can eject it or not as you want.
    All settings including wifi, coinpairs, etc will be saved internal. They will update when you put in a modified configuration. No data folder on SD-Card is needed for graphics anymore as they moved back to internal spiffs memory.

    You can simply use and edit the config file. All done.

  • Hello all, thank you so much for the hard work on this project! I created a video demo flashing the M5Stack with the FW, changing the SD card configurations, and 3D printing a desk stand. I hope this helps more novice users get started

  • Has anyone been able to port this to the Core 2? I tried but the SD Card library seemed to be incompatible.

  • I saw a crypto project on the M5Stack and had to comment!

    First of all congrats to @frittna for the good execution of the concept. Didn't try it myself, but looks great on the photos!

    Seven years ago I started working on a similar crypto project. Decided to go all the way from idea to market, not just because I love crypto, but because I wanted to gain the learning and experience on the way. It was worth it!

    I've seen a lot of "weekend projects", but none of them had the features I wanted or was easily configurable by non-technical people. So I brought my crypto project to a full commercial product. I call it the TicrThing - your dedicated price ticker. (sorry for the obvious ad)

    The previous versions had custom-made hardware, but they always lacked something... Once I discovered the M5Stack, I thought it was a perfect fit. So I completely re-wrote my code for the M5Stack, wrote also the server side, and released the new product earlier this year. Hope this helps bring the M5Stack platform to a wider audience!


    P.S. It was not my intention to hijack the thread, but to share the story of a similar crypto project and how it evolved to use the M5Stack.

  • 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.

  • For those who are interested in trying out the TicrThing for free, you can now find the firmware in the M5Burner.


  • @m5er could you please clarify how to and where to download your version of the crypto ticker to try? M5Burner does not lead anywhere

  • Anyone knows how to to obtain TicrThing version of the ticker for test?

  • Hi, the M5Stack stand has an DHT12 sensor for temperature and humidity integrated. I woud like to integrate this output in my BTC ticker. Any hints how to do this? Or where to start? I have not much experience with M5Stack or programming at all...

  • Hello,

    Here you go! I coded some lines. Try this from there:

    just download the M5Burner zip packet, extract it to a path with no spaces in name (causes errors!) run M5burner.exe and select COM + BAUD + Crypto_Coin_Ticker_Sensor_Cel.ino or the Fah version for Fahrenheit and give it a try.

    BTW: it is a SHT30 Senor built in my base, not a DHT12 although it is written in the description. The temperature is pretty high since the sensor is getting heat from the device itself i guess, maybe a problem of many small devices with temp sensors built in.

    *** For regular users without the vertical base i recommend to use the normal version because i had to make the info panel a bit larger and loose candle chart hight. **

    edit: I fixed a bug that the user settings were not saved after a restart - reflash from github if you are affected.


  • @gipsyblues I suppose you have figured it out by now (and sorry for late reply - I got no notification for this post). In any case, you can download the M5Burner software, connect your M5stack basic (not core2) and flash the TicrThing firmware. Let me know if you encounter difficulties, preferably in a PM so we don't hijack this thread.

  • @frittna You da man! Haven't had the time to have a look back here, so my late reply. Works like a dream! I see also the offset with the temp but it doesn't bother me so much. Maybe the offset could be dealed with by manually giving a correction factor at startup?
    So thank you very much, I am deeply impressed like only a layman (in coding) can be :-)

  • I have followed the instructions step by step in my M5Stack ESP-32 and that's what I get:

    Can anyone help me with the mistakes?

  • @pirix
    i have not set up an enviroment for compiling in osx yet, i can't say.. sorry

    @Albman THX! , yea maybe i'll implement a temperature correction some day

  • @frittna I tried with M5Burner in Windows and compiling it on Ubuntu with the same problem: freezes trying to connect to Wi-Fi.

    Any option?

  • @PiriX
    when you say you burned it with the burner than it should work. I only think of a sd config file corruption or something because of not safe ejected.. or some strange letters in wifi-pass.. i dunno..

    I tested with my guest wifi: "guest" pass "guest" and doesn't work

  • Now it works...

    The problem was "_" in the Wi-Fi

    Thank you so much for your patience.

  • Hi frittna,

    Awersome work for making this for us, its a struggle to keep watch of the crypto market while also living a life away from it.
    I'm a noob, but i'm sure if I know exactly where to edit, i could get away with it, so my query is how do edit one of the existing
    timezones to get my local timezone option? I'm looking for GMT +8 (Singapore/Kuala Lumpur Timezone). Thanks is advance!
