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

@yashax

Hi,
regarding TIME token - I see 4 different tokens with that name but none of it is listed on binance.

An optional cycling function like you're asking was added in the last version i've released a month ago.
Scroll up or go to the github source page.
btw: do you have a core1 unit now?

@frankchau93
i started from zero too so maybe give it a try and search/test if there are other compatible libraries. Since i have no core2 device and beside the (stupid) fact that i cannot use the latest boardmanager (higher than 1.0.4) on a core1 I am kind of stuck. But i guess not forever.. atm i am not really plessed with free time but we would need to know what is causing the problems with boardmanager 1.0.5 and higher first. I suspect the WIFI, the SDCard or the Websockets library. Then only minor changings in code are needed to support core2 i guess.

Thank you. What is the location of the M5Burner source?

you find the link is in the first post

download project: https://github.com/frittna/Crypto_Coin_Ticker

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

The new M5Burner does not allow to select the zip file to burn.

what do you mean?.. try downloading new from source and follow readme

@yashax

well.. i don't have a Core2 unit to test, only Core. I have read a few lines and that there is not much difference for old Core apps to run .. something changed at the power-state chip and its command for example.

One good thing is that you can select Core2 in Arduino and compile it right away without any errors :)

from compiler:
Sketch uses 1225886 bytes (18%) of program storage space. Maximum is 6553600 bytes.
Global variables use 55364 bytes (1%) of dynamic memory, leaving 4466620 bytes for local variables. Maximum is 4521984 bytes.

BUT when you want to have Core2 board in your Arduino you need to load ESP32 Boardmanager version 1.0.6 and my code locks up with a stack overflow error for unknown reason when i use 1.0.5 or 1.0.6... not at compiling but when it connects to wifi. This was an issue a year ago and never solved it because i don't know what changings at the board library causes the conflict.
I think a real M5-Stack freak could find the cause easy (or knows it already) because there must be many other apps i guess after 1.0.5 came out whith same problem. But since i don't know where to start i have no fix for you Core2 users atm

@reddai
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

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)

Hi and thank you very much. Yea, it's really a good alternative to a pc running all day or checking your mobile all the time. You can focus on other things and have always an eye on it. It's nice to have one under your pc screen btw.

to your question, the corresponding part is the following. You would have to add for example your Zimezone as nr.8 in the code and compile it new in Arduino, then set the same number in the sd-config to load this setting at least once. If you're really new to arduino its a bit tricky with all the libraries and stuff (boardmanager!) but it is documented.

Problem right now is that i dont know where to find the correct TimeChangeRule values for your timezone (UTC+8 is SGT ...?)
Maybe you find some info. I found the lines i used in the code on the web or in Arduino code examples but i know no more zones right now.

here is the part at the beginning
TimeChangeRule summer_aedt = {"AEDT", First, Sun, Oct, 2, 660}; // 0: Australia Eastern Time Zone (Sydney, Melbourne)
TimeChangeRule standard_aest = {"AEST", First, Sun, Apr, 3, 600};
TimeChangeRule summer_bst = {"BST", Last, Sun, Mar, 1, 60}; // 1: United Kingdom (London, Belfast)
TimeChangeRule standard_gmt = {"GMT", Last, Sun, Oct, 2, 0};
TimeChangeRule summer_eest = {"EEST", Last, Sun, Mar, 3, 180}; // 2: Eastern European Time (Bulgaria, Greece, Romania, Ukraine, Egypt)
TimeChangeRule standard_eet = {"EET ", Last, Sun, Oct, 4, 120};
TimeChangeRule summer_cest = {"CEST", Last, Sun, Mar, 2, 120}; // 3: Central European Time Zone (Frankfurt, Paris)
TimeChangeRule standard_cet = {"CET ", Last, Sun, Oct, 3, 60};
TimeChangeRule summer_edt = {"EDT", Second, Sun, Mar, 2, -240}; // 4: US Eastern Time Zone (New York, Detroit)
TimeChangeRule standard_est = {"EST", First, Sun, Nov, 2, -300};
TimeChangeRule summer_cdt = {"CDT", Second, dowSunday, Mar, 2, -300}; // 5: US Central Time Zone (Chicago, Houston)
TimeChangeRule standard_cst = {"CST", First, dowSunday, Nov, 2, -360};
TimeChangeRule summer_mdt = {"MDT", Second, dowSunday, Mar, 2, -360}; // 6: US Mountain Time Zone (Denver, Salt Lake City)
TimeChangeRule standard_mst = {"MST", First, dowSunday, Nov, 2, -420};
TimeChangeRule summer_pdt = {"PDT", Second, dowSunday, Mar, 2, -420}; // 7: US Pacific Time Zone (Las Vegas, Los Angeles);
TimeChangeRule standard_pst = {"PST", First, dowSunday, Nov, 2, -480};
Timezone myTZ0(summer_aedt, standard_aest); // myTZ0: 0 Australia Eastern Time Zone (Sydney, Melbourne)
Timezone myTZ1(summer_bst, standard_gmt); // myTZ1: 1 United Kingdom (London, Belfast)
Timezone myTZ2(summer_eest, standard_eet); // myTZ2: 2 Eastern European Time (Bulgaria, Greece, Romania, Ukraine, Egypt)
Timezone myTZ3(summer_cest, standard_cet); // myTZ3: 3 Central European Time Zone (Frankfurt, Paris)
Timezone myTZ4(summer_edt, standard_est); // myTZ4: 4 US Eastern Time Zone (New York, Detroit)
Timezone myTZ5(summer_cdt, standard_cst); // myTZ5: 5 US Central Time Zone (Chicago, Houston)
Timezone myTZ6(summer_mdt, standard_mst); // myTZ6: 6 US Mountain Time Zone (Denver, Salt Lake City)
Timezone myTZ7(summer_pdt, standard_pst); // myTZ7: 7 US Pacific Time Zone (Las Vegas, Los Angeles);

and later in the code:
..} else if..=4..
..} else if..=5..
} else if (myTimeZone == 6) {
time_t now = myTZ6.toLocal(time(nullptr), &tcr);
M5.Lcd.printf("%s %2d.%s %02d:%02d", weekDay_MyLang[weekday(now)], day(now), monthName_MyLang[month(now)], hour(now), minute(now));
} else if (myTimeZone == 7) {
time_t now = myTZ7.toLocal(time(nullptr), &tcr);
M5.Lcd.printf("%s %2d.%s %02d:%02d", weekDay_MyLang[weekday(now)], day(now), monthName_MyLang[month(now)], hour(now), minute(now));
here the new else if for nr.8
...
...
i think that would be all

@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..

@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

Hello,

Here you go! I coded some lines. Try this from there: https://github.com/frittna/Crypto_Coin_Ticker

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.

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.

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 M5Burner_Crypto_Coin_Ticker.zip and edit the config file. All done.

@wwhite

Yeah !!! - I'm glad you figured out that the board manager was updated without your notice! This is helpfulf for others as they can easiliy run into the same scenario i guess. If the SD-Card in not read correctly it will at least give you some lines on the display and serial output. I use FAT32 on a 2GB SD and always "safe remove" before unplugging the card from cardreader.

@wwhite said:

If I'm compiling this way can I still use the config files on the sd card or do I have to hard code the wifi info?/

You can hardcode network settings but it doesn't matter and it's not intendet to do so in this sd-card version. When a sd-card is read-in and if the config file contains a ssid/password, it will use it. They will be stored in internal memory aswell (only ssid/pw1+2) and be used if no SD-card is inserted by accident.
In this case it should connect as usual but with the 4 default coinpairs and missing images from the /data/ folder as they are loaded from there.
BTW: I have an identical SPIFFS version on github (public folder) where you hardcode every setting in Arduino and have to upload all graphic files to the internal SPIFFS memory with esp32-data-upload tool, so no sd-card at all is needed.

But for me it was important to make a SD-card version to provide an much more "easy solution" - without compiling by yourself.
So theres no need to edit the Adruino code.

@wwhite
hi!
maybe it is the wrong board manager? at menu: tools -> boards -> boardmanager - search for esp32 -> select version 1.0.4, not the new 1.0.6
have you tried the serial monitor to see what the serial output is? is there any, at 115200 baud rate?
btw: the one warning about avr architecture is no problem, its ok.

Finally i updated my project to a version with a SD-Card config file for Wifi-Settings and coinpars, colors, etc.

Now if you don't want to compile on your own you can load the precompiled .bin file with populair SD-Menu Loader App and get around all the hardcoding in Arduino-IDE with all the librarys and esp32 board manager..

all you need is to flash my .bin and have a sd card with a folder in root called "ccticker" which holds the file "ccticker.cfg" and the "data" folder for the graphic files.

I do not use SPIFFS memory anymore because it is easier without for the most people.. (btw: does anyone know if it is possible to burn with m5burner AND flashing spiffs together? Any info on m5burner to get the file and folder format right to flash a custom program like this?)

have luck

download my app at https://github.com/frittna/Crypto_Coin_Ticker/

@silvereq
thank you very much for your information

i will update the instruction and btw, i am almost finished with a modified version of the code so that you can insert a config text file onto a sd card wich only has to contain the wifi-settings, timezone, pairs and the color of its name. I will updatede https://github.com/frittna/Crypto_Coin_Ticker soon.
It will then be much easier to "burn" the compiled app into the M5 and nobody needs to compile on its own if he is not intended to change or improove the bitcoin price ticker

thx!
