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.
Especially the wifi version could be the cause of the incompatibilty i guess:

have luck

@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 more functions since then.
A little problem i have experienced is the wake-up behavour on usb-cable because with the battery base it behaves different as it is with standart battery back. But this can be solved in the code if you change the settings at //Power Settings

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 a Crypto Coin Price Ticker which I have modified and enhanced to use with the M5Stack.

The original core of the code was from a github users project github.com/olbed/bitcoin-ticker
I ported it to M5, added some new features and design changings and now I want to share my resutls to all of you who wants a nice price ticker to track your favorite crypto pairs easily.

download project: https://github.com/frittna/Crypto_Coin_Ticker
in general, read the info at the beginning to get it working with all the libraries and the SPIFFS upload
edit: btw - look at this rise in btc from march to august..
