Great lib but issue on arduino ide 1.8.3

[gilles2908]

Please, i haven't succeed to install the library using the zip file but with the .cpp and .h import in my project, i have been able to run your touch button and it's work perfectly ! BUT i have a message on monitor while setup ( ex for 4 buttons declared )
However , my program works but it's disturbed to see theses lines . Do you have any idea, what's the origin of theses lines
and how could i be able to make them disappear ! Thanks a lot for that job ,Asynchro Touch with callback is very useful ! that will be great if you have 1 moment to answer
( I think but not sure , i don't have any esp32-arduino-lib-builder ( installed ) - config arduino 1.8.3 windows 10 )

Hi,

you need to call the begin() function before using the filter. This will initialize the filter.
See line 77 of the example file:

ESP32Touch/src/examples/esp32_touch_example.cpp

Line 77 in 911cdf2

buttons.begin();

Best wishes,
Ulrich

Hello Ulrich thank a lot for your answer , now i have found the problem due to calibrate_thresholds()   just before begin ! so now i don' t have anymore the long phrases errors on monitor during setup ! Great, now i'm so glad  !   (and i have tested several touch libraries and yours is the best ! ) But i'm still facing a tiny issue with touch_buttons  like ESP32touch ! When i try to install the zip library using classic method from arduino ide! i have a error message saying -> Specified folder/zip file does not contain a valid library If i unzip your library and copy folder in my user/library...  OR in program file(x86) arduino library and use the basic example like the link in the mail , i still have errors saying -> ESP32Touch.hpp  no such file or directory SO the only method i have found, it's to import 3 files ( cpp h & info_debug_errors ) in my project and change #include<> with #include"" and this work very well ! but it's not very convenient ( i mention , that i have recently installed some zip libraries without problem ) So it's weird !! If you have an idea about the reason, probably i still will use your library for the next 10 years... i put in attachment some screen  captures, if you have a moment to take a look ! However , i can use it so .... and i thank you a lot for your job on this library very useful and for your help Regards Gilles ‌   De : "ul-gh" A : "ul-gh/ESP32Touch" ,"gilles2908" ,"Author" Envoyé: lundi 11 Août 2025 20:11 Objet : Re: [ul-gh/ESP32Touch] Great lib but issue on arduino ide 1.8.3 (Issue #4)   ul-gh left a comment (ul-gh/ESP32Touch#4) Hi, you need to call the begin() function before using the filter.
