Hi guys, I'm scratching my head to figure out why I need to add function prototypes in the main file? If I don't the code won't compile. I have created a class with a method that can have an optional parameters, which I read could be the cause of this issue. // Main file // .... void serialPrintT…

[image] el_pablo: I'm using Platform.IO I think this is your answer. I am not very knowledgeable on PlatformIO (note the name is "PlatformIO", not "Platform.IO"), but it is my understanding that it does not have the automatic function prototype generation that the official Arduino development…

Your class file is a .h file. You include that .h in the main file which is the .cpp file and you include that .h file in the files that need to know about the class.

Sorry, I forgot to mentioned. The main file already includes the SomeClass.h The SomeClass.cpp includes the SomeClass.h SomeClass.h has all the required inclusions. SomeClass.h has a header guard If this can help : there is a function pointer for a callback in SomeClass.h I'm using Platform.IO …

Can you also post the full .cpp file and a basic example sketch?

Your example (post #1) isn't rich enough to see if your problem is that, without specifying a prototype, you would fall foul of the following feature: "automatic generation of prototypes" which affects .ino files. Generated function prototype injected before declaration of custom parameter type · I…

As requested here are my files. #include "LyneTracker.h" LyneTracker::LyneTracker() : ss() { // Initialize sensor pins (from pin 0 to 4) for (uint8_t i = 0; i < nbSensors; i++) { sensorPins[i] = i; sensorValues[i] = 0; // Initialize cached sensor values to 0 sensorM…

Like I wrote, I have reordered the functions to workaround the prototypes requirement. Here's the output. * Executing task: C:\Users\nicol\.platformio\penv\Scripts\platformio.exe run Processing megaatmega2560 (platform: atmelavr; board: megaatmega2560; framework: arduino) ---------------------…

Your sketch compiles for a Mega when using IDE 2.3.3 with AVR board package 1.8.6. There are some warnings. Notes: The missing library so others don't have to look for it: GitHub - Makeblock-official/Makeblock-Libraries: Arduino Library for Makeblock Electronic Modules, learn more from Makeblock …

Here's a failing output. * Executing task: C:\Users\nicol\.platformio\penv\Scripts\platformio.exe run Processing megaatmega2560 (platform: atmelavr; board: megaatmega2560; framework: arduino) -------------------------------------------------------------------------------------------------------…

I confirm that the problem comes from PlatformIO. I built the code under Arduino IDE and I works like intended. Thanks all for helping me out to find the culprit!

Can you show the compilation output (verbose).
