Re: Does the ESP32-EVB have some LEDs that I can control ?

I switched one on which also operated the relay to show when my software was running normally. The visual and audible confirmation was useful, but I chose not to send high frequency LED flashes on this pin on this board, but I was only using ESP32-EVB for initial testing. I also did that, but the p...

Does the ESP32-EVB have some LEDs that I can control ?

Hello ! I've been looking at an ESP32-EVB for the past couple of days and there is a "big" LED on it named LED3, but that is an IR transmitter and I can't use it like a normal LED. Does the board have some LEDs that I can control ? I've been looking through documentation but I couldn't find a thing....

Have you solved this problem?
No, the https://github.com/NeoCat/ESP32-P3RGB64x32MatrixPanel library is very bad.

I've opted for this one: https://github.com/pixelmatix/SmartMatrix/tree/teensylc

It is maintained and it has a forum. And above all: it works perfectly.

Re: Is there a way of making a file and then download it using a web-server and a browser without touching the file-syst

After some digging I managed to make a download method: if (request->hasParam("filename", true)) { // Check for files: <input name="filename" /> if (request->hasArg("download")) { // Download file: <button name="download"></button> Serial.println("Download Filename: " + request->arg("filename")); As...

Re: Wrong Magic Byte error when trying to upload spiffs.bin

Isn't this line wrong? For "spiffs.bin", indexOf("spiffs")==0 so it won't be detected as U_SPIFFS type. int cmd = (filename.indexOf("spiffs") > 0) ? U_SPIFFS : U_FLASH; Try int cmd = (filename.indexOf("spiffs") > -1) ? U_SPIFFS : U_FLASH; I've changed it to >= and it works just as well. Thank you !
