ATmega328 DIP versus ATmega 328 Quad Flat package

Hello all.

The ATmega328 Quad Flat Package has more 2 ADC lines. If we download the Bootloader as well as the program, can we read those 2 additional lines with "analogRead6" and "analogRead7"?

Thanks and regards,

No but you could easily modify the wire library to allow you to access them.

Doesn't the seeeduino 328 have those extra pins broken out?

You might want to take a look at that.

Your correct, the feature list states it:

Hello all.

Thanks for the very useful information. As far as I understood the Arduino Duemilanove Atmega328 compiler also supports the "analogRead 6 and 7" but the pins aren't available due to its a DIP package, so, the function doesn't work. Considering this, the Arduino Pro Mini 328 - 5V/16MHz is also compatible with the Duemilanove Atmega328 in terms of accessing the AD6 and AD7.
Can you please confirm this last statement?

Thanks and regards,
Manuel Silva
