I'd like to build one of this Amazing SIO2Arduino. I have seen that some software modifications are been done by some of you, and for this reason i have some questions. The first one, is related to files navigation. The original version seem to use one key only, to pass from one file to another, so, it isn't possible to back on the previous file, am i right? If yes, i noticed that someone has modificed the software to use the LCD+Keypad shield, so, i'm wondering if the keypad is used or not. If yes, is it possible to have your version of the software please? It's difficult for me to modify the original software, so, some help would be really appreciated.
I need to build the device on an Arduino Mega2560, and i have to buy the missing parts (SD reader\writer, LCD display etc...), your advices are wellcome.
Please, let me know! Have a nice day guys!!
