tone() not found

[erich74]

Hi, First off, thanks a lot for your work, I am starting with those Sunton boards and this is really helping. I have setup a PIO/VSCode project to compile your demo code as a starting point for my project. When compiling but I've got this error:

.pio\libdeps\esp32dev\esp32_smartdisplay\src\esp32_smartdisplay.cpp:139:38: error: 'tone' was not declared in this scope

I understand tone() is part of Arduino core library but looks like this is not part of the arduino declination in PIO.

Do you have an idea how to fix it? Thanks! Eric

Hi Eric,

Thanks for mentioning it. I'll have to look into this because it worked. Maybe something was taken out of theArduino core. I'll have to take a look what's going on.

In the mean time, if you're not using it I suggest you just star out the beep function in esp32_smartdisplay.cpp (in the .pio srouce directory).

Enjoy!

Thank you very much for your quick answer. I was planning to use it but I have an 8ohm speaker being shipped so this is not really urgent. Yes I did comment out this line and compilation was ok. Thanks again, you are doing an amazing job, I have ordered additionnal boards (different sizes with capacitive touch screen) thanks to your project I can easily setup new project without the complexity and flaws you have sorted out for us!

Still very strange. I re-triggered the build action that is used to rebuild. This worked fine. Are you using a special library for the esp-32. Have you tried upgrading the packages?

[erich74]

Here is my platformio.ini, I have not set any additionnal library for the moment:

[env:esp32dev] platform = espressif32 board = esp32dev framework = arduino monitor_speed = 115200

build_flags = -Ofast

-Wall

Hi Eric,

I see there are different versions. See below the output from the build action..

You could try to update your system; try pio pkg update

Maybe this helps...

Kind regards,

Hi Rene,

It works now after pio pkg update ! Thanks a lot! Eric

[rzeldent]
