Hi! I'm a little confused about how many I/O lines that are accessible externally. I'm only interested in using them as out lines in this case, how many of the 6-pin (U28) and 10-pin (U2) connector pins can be used as out-signals? (Looking at the datasheet I see it as 2 + 4 = 6 I/O in total) How much voltage would that correspond to, same as ~Vcc?
Also, if I wanna communicate with and external device, would using the I2C buss be a good alternative for sending 6 I/O signals? Are there any simple IC circuit that can receive the signal and convert back to 6 separate lines? Can the (U2 pins 1 and 9) AVcc and Gnd be used to drive the external device? I'd be glad for any help on the matter and if possible some code piece showing how to get the I/O lines in one or both technologies. Best Regards Erik
