automatic software reset curcuitry - I am using ubuntu linux and pump the reset button then click upload and it works. Now I hear the arduino systems have a automatic software reset is that automatic for all OS?
"hardware flow control lines (DTR) of the ATmega8U2 is connected to the reset line of the ATmega328 via a 100 nanofarad capacitor. When this line is asserted (taken low), the reset line drops long enough to reset the chip."
That is how the arduino UNO does it referencing the hardware section :
