I am making MPPT based solar charge controller using ESP32. I got this error when I tried to compile the project in Arduino IDE where I need to operate the LCD parameters using buttons. The output must look something like LCD display should show the values based on the push button input. But it is not happening instead the error "insn doesn't satisfy its constraints" is popping up. Kindly help me what can be done in solving this error and make my project work...????

which project, which source code?

➜ please read How to get the best out of this forum and post accordingly (including code with code tags and necessary documentation for your ask like your exact circuit and power supply, links to components etc).

sterretje · July 26, 2024, 9:47am

I could see an attempt at code tags so I fixed your post. Code tags are three backticks (not a single tick) on their own lines before and after the code

```
your code here
```

Your code is missing parts; not sure why but the code that you presented is only 443 lines long. And as it's missing loop() and setup() and possibly other stuff (I suspect that they are in other ino files) we will not be able to reproduce.

Please describe the history of this project. Did you write it yourself? Or did you copy it from somewhere? Did you test your lcd menu on its own without integration into other code?

Note that the problem with multiple ino files is that a mistake in an other file (alphabetically before it) can result in errors in the next file (e.g. an error in a.ino can be reported as an error in b.ino).

Lastly, you might be the victim of the V3.x of the ESP32 board package where a lot of stuff was changed. Rolling back to the last V2.x might solve the problem (for now); older code that you did find on the web might not have been reworked for V3.x.

Note:
I have no experience with ESP32 based boards.

Hello Sir @sterretje

As you said you don't have any experience in ESP32 based boards, then sorry to hear from you that I copied code from somewhere else. As my project have multiple tabs in it, I am facing only this error at this particular point of code with LCD interface with buttons in ESP32. There were no errors in the previous tabs of my code where I tried in disabling the error code and tested the remaining. There is no issue with the other part of code. That's the reason I posted the part of the code along with the error.

I could not post entire project code here since it has multiple tabs in it.

sterretje · July 26, 2024, 11:50am

I just asked. It's a long piece of code and somewhere it went wrong.

I gave 2 pieces of advice

Try your code in a smaller application.
Roll your board package back to see if it solves the problem.

Good luck.
