When I try to compile onto esp32 error 225 appears any thoughts on how to help?

Projects General Guidance
1

Even when I try just a uploading nothing it pops up and I’m really wanting to get over this so if any of you have solutions please share

2

No, for you have provided no useful or actionable information.

3

Just declaring any variable or blink command

4

Post the complete error message.
Does it occur while uploading or while running.

5

Uploading and compiling can’t get it to run, I will get error message

Looks like maybe a library is missing, but with no code auto-formatted and posted in code tags as well as verbose output also in code tags we can only guess.

Ok thanks for the information I will try that!

Are you using micropython?
Which version of the IDE?

In the IDE click on Edit, then Copy for Forum, that will copy your code.
Come back here and just do a paste.

/*
  Button

  Turns on and off a light emitting diode(LED) connected to digital pin 13,
  when pressing a pushbutton attached to pin 2.

  The circuit:
  - LED attached from pin 13 to ground through 220 ohm resistor
  - pushbutton attached to pin 2 from +5V
  - 10K resistor attached to pin 2 from ground

  - Note: on most Arduinos there is already an LED on the board
	attached to pin 13.

Oops wrong one,

I don’t think I have micro python being used rn how do you use it?

14

I’m trying to load a sketch to Arduino IDE 2.3.4 and I get this error (Compilation error: exit status 255) can someone help ?

15

I compiled it OK
Did you download and include the BLEkeyboard library zip file?

16

Let me check

17

Ok. I don’t have it. Just downloaded it and tried to load to Arduino and the .ino file won’t allow me to click on and finish load

18

Are you working with @randomhandwiredcircuit

19

No sir. Doing my own project to wirelessly operate my ESP32 using my ESP32 kit app on my iPhone. Just need to verify my sketch and load to ESP32 control board

Do you have the same exact problems as discussed in posts #1 through #13
