With "buffer limit" I meant the limit given by SoftwareSerial

comment Send big amouts of data to PHP script via gsm module SIM800L
Thank you very much. My problem was in fact the buffer limit. I made a workaround where I would add every GET paramater seperatly in a function and only at the end I made a commit by writing \r\n so it gets interpreted as one big command.

comment Arduino Micro behaves unusual
Thank you. Flashing the printing program did the job. Somehow my other program made the entire Arduino unresponsive.

comment SIM800l doesn't respond on arduino micro
Thank you for your advice but I still get nothing returned. Only the RX led on my arduino is blinking but nothing arrives on tx. I tried mapping rxd to txd, put it to port 9,10 then back to the RX,TX ports but nothing gets me a response :/

comment Multiple definition error when linking firmware.elf
Thanks a lot :) I tried to declare and initialize it in myLib.cpp and forgot the extern-keyword in myLib.h.

comment Multiple definition error when linking firmware.elf
Could you maybe give me an example on how to do this properly? I'm sure this sounds trivial to you but I hardly understand what you've said.

comment Use 5V SD-Adapter on 3.3V System
why is it a workaround if it has even bulit in such a chip? so can i use it safely and no 3.3v electronics can get damaged? of course if the wiring is right

comment Use 5V SD-Adapter on 3.3V System
So how should I wire it? Just connect to SD-VCC with the 5V output of the Arduino . And put both ground pins together and the arduino won't be affected by this higher voltage because on all the other pins (cs,mosi,miso and sck) it will send all the data with 2V high an 0.8V low? So nothing over 3.3V wich would harm this arduino?
