Thank you for this! I was going to buy a ticker but now I will make my own. Keep the great videos coming! They are very helpful and educational.
Excellent travail, reste a vérifier .... Thanks.
Love the project, I have an issue though. I enter the correct ticker into the basic local IP, the matrix blanks, shows the IP again and never shows the ticker. Any ideas?
Normally this is the case with a ticker which is not retrieved from finance.yahoo.com/. Are you sure you are using a correct ticker like BTC-USD ? You can also check if you used the correct webserver library (ESPAsyncWebServer by Me No Dev). I hope this will help.
Hi, great video and thank you. but when I try to submit ticker symbol, my ESP crash with error "Guru Meditation Error: Core 1 panic'ed (LoadProhibited). Exception was unhandled." would you have solution for this error? thx in advance.
I've tested it more and the error appear only if the price for any ticker is greater then 9.99
@@TolueNT Strange. I uploaded the code again myself and everything works fine, also with prices above 9.99. Maybe you can check if you used the right ESPAsyncWebServer library. Otherwise install the library from the link in the GitHub. It is also possible you have selected the wrong board, just try another one. I hope one of these action will solve your problem.
@@BloxyLabs I had to increase price buffer in this line " char pricebuffer[sizeof(tempmarketprice)+10]; " from +1 to +10 and now it works :)
and do you think would be possible to make the ticker scroll without whitespace? I'm trying to implement it from example in arduinio ide "MarqueeText" but it doesn't work :(
@@TolueNT Nice to hear you got it to work and letting us know what you did to fix it!!!
bro, when you upload the code to the esp32, can you tell me "how to connect" to the pc? it's via usb ? i saw, you select in your case COM3... i dont want damage my first esp32 :D
You need to use a USB cable which supports data transfer. Then everything will be fine ;). Have fun with the stock ticker!
@@BloxyLabs thank you , greetings from Argentina.
For me, it didn't work, but god bless for chat gpt :D
