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!

I will post the end of my compiling log below so you can see my used lib versions.

@batucker
Hi, i was not able to track down the compatibility issue you both have. But it has to be related with my or your arduino version or wifi version used in it. It would be helpful if i would know if anybody has NO issues with my installation guide, since i know it is working for otheres too.. I was testing it on a fresh Win7x64 pc, my usual pc is win10 x64, Standalone or MS-AppStore-Version was no different and both are working good.

But after all it would be best to make a quick version to load a precompiled BTC-PriceTicker file with the common SD-Loader App like many other apps from the community. With a seperate "settings.cfg" file which will be edited to only contains personal wifi settings and the coins you like to see. >>update: >>I tested the a promising ardunio library "SDConfig" which would be perfect but it will take some time to implement it..)

even better would be an simple osd-settings menu with button access inside the PriceTicker but that's no easy job for me without the experience of coding this on the m5 yet.
...

@innovationsmaker no i don't have the new Core2 version or know further details but i guess it will need only minor adjustments..
I hope someone will try it out and post the results. Would be interesting for all other existing apps too..

@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.

it's the inverted original.. have you tried it on your M5? Then you can easely change it to any color you like in paint or use the bright original one m5_logo.png instead of m5_logo_dark.png, it is included like all other files you will need to compile it. I just like green.

you can try this pice of code which is working for me:
.

.

#include <WiFi.h>
#include "Free_Fonts.h"
#include <M5Stack.h>

const char* ssid = "your_host";
const char* password = "your_password";
WiFiClient client;

void setup() {
M5.begin();
// Connecting to WiFi:
M5.Lcd.setFreeFont(FM9); M5.Lcd.setTextSize(1); M5.Lcd.setTextColor(TFT_WHITE);
M5.Lcd.print("\n\nConnecting to ");
M5.Lcd.println(ssid);
WiFi.begin(ssid, password);
while (WiFi.status() != WL_CONNECTED) {
M5.Lcd.setTextWrap(true);
M5.Lcd.print(".");
delay(500);
}
M5.Lcd.println("\nWiFi connected");
delay(1000);
M5.Lcd.fillScreen(TFT_BLACK);
}

void loop() {
showWifiStrength();
delay(2000);
}

// show Wifi-RSSI level (signal strength in 4 bars + dBm )
void showWifiStrength() {
int WifiRSSI = WiFi.RSSI();
M5.Lcd.fillRect(40, 0, 68, 15, TFT_BLACK);
M5.Lcd.setCursor(40, 14);
M5.Lcd.print(String(WifiRSSI) + "dBm");
if (WifiRSSI > -50 & ! WifiRSSI == 0 ) M5.Lcd.fillRoundRect(26, 1, 5, 12, 1, TFT_WHITE);
else M5.Lcd.fillRoundRect(26, 1, 5, 12, 1, TFT_DARKGREY);
if (WifiRSSI > -70 & ! WifiRSSI == 0) M5.Lcd.fillRoundRect(18, 3, 5, 10, 1, TFT_WHITE);
else M5.Lcd.fillRoundRect(18, 3, 5, 10, 1, TFT_DARKGREY);
if (WifiRSSI > -80 & ! WifiRSSI == 0) M5.Lcd.fillRoundRect(10, 5, 5, 8, 1, TFT_WHITE);
else M5.Lcd.fillRoundRect(10, 5, 5, 8, 1, TFT_DARKGREY);
if (WifiRSSI > -90 & ! WifiRSSI == 0)
M5.Lcd.fillRoundRect(2, 7, 5, 6, 1, TFT_WHITE);
else M5.Lcd.fillRoundRect(2, 7, 5, 6, 1, TFT_RED);
}

Hi everyboy,

I made good progress with my project, a Crypto Coin Price Ticker for monitoring crypto currencies on your desktop. I have modified and enhanced some existing code to use with out M5Stack Device

The original core of the code was from a github users project github.com/olbed/bitcoin-ticker
I ported it to M5, added some many new features and design changings 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.

download project: https://github.com/frittna/Crypto_Coin_Ticker
read the info for the easy installation method or compile yourself
edit: btw - look at this rise in btc from march 2020 to now on the picutures
