Hi Mike, I'm wondering if you've used the ADC functions of this GPIO board with Linux? And, if so, how well do they perform? Thanks, 73, David KB4FXC On Sun, 16 Feb 2014 mike@midnighteng.com wrote:
While I love the rpi, I am waiting for a new board based on the snapdragon s4 quad core. It will be a while waiting for that to turn up but at 1.4ghz per core, not much we can't do with it. I don't like stuffing it all into something that will not expand one IOtta (pun intended) when done.
But getting gpio through the pi and not specifically writing using the pi's own gpio pins (best option) leaves you with little options. However, if you were to write for something external, I might suggest a usb gpio board like this found on ebay
