I've been messing with some code for the DS18B20 digital temperature sensor and everything was fine, but I've got greedy and wanted to mess up with three sensors and OneWire library.
I didn't knew the exact code for the multiple sensors, so started to figure out something on my own.
The effect was tragic... I've probably exceeded an array size (stupid mistake) and it's just on the beggining of the code. So my board freezes immediately after start. Because of that - I can't force it do enter programming mode. It's not reacting for the reset button nor the Arduino IDE is able to communicate with it. When I hit the button "board information" - it reads Arduino Uno, shows serial number etc, but I think this comes from the programmer (usb-serial). When I try to communicate with the CPU itself - it simply doesn't respond.
Does this mean that the CPU is bricked, or is there any chance of some rescue?
Thank you in advance,
