Greetings!
I’m new in this community, but I hope there’re a lot of helpful people around here.
I use PIO with Visual Studi Code, and I had to change my Arduino ADK board to Arduino Mega 2560, and rewired it, because ADK has died.
So I simply changed my platfomr.ini for this:
platfomrio.ini
The platform_packages =
- ; use GCC AVR 7.3.0+*
- toolchain-atmelavr@>=1.70300.0*
is for FASTLED library.
So, after that I rebuild my project, and I got these nice errors. I guess the problem is with the adafruit RTC library…
Could somebody help me out?
I tried reinstall PIO, PIO core, Visual studio code, but noone of them helped me out.
Thx,
Daniel

Can you give your full platformio.ini? It seems that the error just lies in the TinyWireM library being incompatible with your target, which is included by the RTC library.
Edit: Actually I don’t see why a Mega2560 would need that library at all, since it’s written for ATtiny chips. I suggest you try adding
lib_ignore = TinyWireM
to the platformio.ini.

Hi!
I linked it before, but here is my modified platformio.ini (I added that you suggested), but then it stops at rtc.begin();
;PlatformIO Project Configuration File

; Upload options: custom upload port, speed and extra flags

[env:megaatmega2560]
platform = atmelavr
board = megaatmega2560
framework = arduino
lib_deps =
FastLED
platform_packages =
; use GCC AVR 7.3.0+
toolchain-atmelavr@>=1.70300.0
monitor_speed = 115200
upload_port = COM13
monitor_port = COM13
lib_ignore = TinyWireM
Since it’s compiling now that’s one error less. PlatformIO tries to include TinyWireM because
https://github.com/adafruit/RTClib/blob/master/RTClib.cpp#L46
and without lib_ldf_mode set to deep+ or chain+, it doesn’t evaluate the #ifdef macro (docs).
What does “stop” mean exactly? No more output? What exact code are you running?
Can you test only the RTClib with its minimal example sketch first (PlatformIO Registry) to see whether the library works with your hardware ok?
I’ll test them that you suggested. But I’ve already commented
/*#ifdef __AVR_ATtiny85__
37. #include <TinyWireM.h>
38. #define Wire TinyWireM
39. #else*/
40. #include <Wire.h>
//41. #endif

Commenting it out shouldn’t be necessary if either the library is ignored via lib_ignore or lib_ldf_mode = chain+ is set.
Your new compilation is missing the RTClib as a dendency. You should explicitly declare it in a lib_deps statement (docs)
Stop means it never reaches line 51 or 55
Here is my setup code: setup - Pastebin.com
If I use lib_ignore=TinyWireM the building and the uploading is success, but the program never reaches line 51 or 55… 
I tested the code that you linked on arduino uno.
it uploaded.

But the RTClib example code does not run on the target ATMega2560?
It runs on Mega too.

It looks like all of the problems were solved. =)
A failed RTC (ds3231) modul was guilty. It communicates via I2C and thus it affected my whole I2C communication… I changed it, and now it’s working perfectly. 
Anyway, thank you for your help.
