/products/roadtest/b/blog/posts/capsense-evaluation-kit---microcontroller-controlFor me one of the nice features of the MBR3 chips is the I2C bus. This allows you to read the status of the switches from a microcontroller with just two wires. If you can spare a 3rd wire then you can also use the &quot;host interrupt&quot; feature ...en-USTelligent Community 12https://community.element14.com/products/roadtest/b/blog/posts/capsense-evaluation-kit---microcontroller-controlThu, 23 Oct 2014 14:31:53 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:9c18d3ec-e8fa-4ac9-a337-83ca1beac54bWorkshopshed0<p>A followup thought on the I2C, you can also use it to read the raw data from the switches and hence calculate things like signal to noise ratios. The power on testing also drops data in here that you can read and act on.</p><img src="https://community.element14.com/aggbug?PostID=18105&AppID=14&AppType=Weblog&ContentType=0" width="1" height="1">
