For some time I’ve been meaning to do a new video which covers why using 100% of SRAM can sometimes introduce bugs. I discovered this when I was working on the Nokia 3120 Keypad SMS Sender, the SMS message that I was sending would be cut short and would have weird characters at the end. I loaded up the hex file in AVR Studio 4 and found that the stack was overwriting my variables!
