That's what my serial output looks like on my project. looks like memory leak or something.
My sketch uses 66% of program memory, and global variables use 45%... so i have some left. It happen on both may arduino boards, so it's not a harware issue. The program itself seem to work properly, but the serial output is mess.
Those shreds of text in the output are fragments of all kind of debug texts I have all over the program. This output appears after start/restart arduino, before turning all the calculations, when no new variables are declared and used. just the global ones.
I noticed that every time the "random text" is the same.
what can it be?
And those fragments appear in radom spans. sometimes one leter a second, sometimes twice a secons. sometime a letter sometimes few letters.
And the program is idle... it doesn't do anything after start. there should be no messeges.
In theese shreds are random strings that go after "Serial.print" or "Serial.println" from all over the program. Those VCC and GND are my error messegaes that they can't be shown at the moment. Like other fragments. The program doesn't do anything at the moment and those shreds appear form all over the code.
There are hundrets line of code, and all worked well... before.
I have MAX31855K thermocouple module connected. But when disconnected the mess still flow.
Hi.
I wasn't at the computer during the weekend.
I found the bud and it was trivial. I had a Serial.print(something) dug in the code with a parameter with a value that was beyond its range and that's why it showed me some random stuff from memory.
Sorry for bothering you.
