(I am on linux)
since I want to start something different, I want to learn how to program the "bare metal" with C.
That is: AVRTools (https://github.com/igormiktor/AV...) + avr-gcc + avr-libc + avrdude + vim....no Arduino (WHICH IS *NO* EXPLICIT
NOR IMPLICIT CRITISM TOWARDS ARDUINO!)
The "bare metal" is in my case an Inhaos Mega CORE mini - a ATmega2560 board which breakout
every pin of the uC.
But before I melt my board a question:
Is it possible to harm the uC by accident using software only and attaching only digital voltmeters or oscilloscope inputs
to the pins (when keeping of my fingers of the fuses)?
Or, the other way round: What is the safest way to experiment with pin settings, control registers etc... without the fear
to burn something?
Thanks a lot for any help in advance!
