Topic: Upgrade from Duemilanove to 16 Analog inputs (Read 2 times) previous topic - next topic

Hi
I have developed a working Analog Data Logger (6 Analog inputs) using VB6 and a Duemilanove. I run Arduino 019 and WinXP. I want to upgrade my Logger to 16 Analog inputs.
I could buy a ATMega2560 but I've seen a number of reports on software, bootloader and USB issues with this board.
I'm not sure how easy it would be to extend the on board software to the 2560.

I would like some advice on whether I should go for the ATMega2560 or another solution or Arduino Board for my upgrade.
Regards
Martin

Thanks Senso
How easy/difficult would it be to interface with my Duemilanove?
It's USB Serial output works really well for me. I wouldn't like to change too much if possible.

You use the SPI interface, and I would bet that there is already one lib to use this ADC with arduino.
The SPI interface uses the digital pin 13,12,11 and 10, you just read it and send the data via serial just like you do using the internal ADC and the analogRead() command.
