You write a piece of software that uses the IOIO API for reading the samples, as in: https://github.com/ytai/ioio/wiki/Analog-Input You probably want the buffered version.
On the hardware side of things, this can be as simple as connecting your probes between GND and the analog pin, or could get slightly more complicated if your signal is not between 0-3.3V, or you want higher input impedance or floating GND, etc. On Tue, Mar 31, 2015 at 1:44 PM, lilach azrad <azlil...@gmail.com> wrote: > Thanks. > Maybe a question of ignorance :\ > How do I get the samples from the analog input? what should be connected > physically besides the BT and power cable 5V-15V? > tried to understand from internet but nothing, hardware is not my > strongest side > > > > > בתאריך יום רביעי, 4 בפברואר 2015 בשעה 22:01:23 UTC+2, מאת Ytai: >> >> Some links, courtesy of Google Search: >> http://www.dash.co.il/index.php?route=product/product&product_id=2511 >> https://www.4project.co.il/product/ioio-otg >> http://www.or-e.co.il/ioio-otg.html >> >> Ordering from Seeed might save you some $$$, on expense of some longer >> shipping time. >> >> On Wed, Feb 4, 2015 at 11:44 AM, lilach azrad <azli...@gmail.com> wrote: >> >>> Thanks! its good enough for my project. >>> There is any distributor in Israel of this IOIO component? >>> if the answer is no - this link is ok?
