MPR121 connecting touch points to see on the web

McGlon

I was curious would be possible to use this product to capture the touch points of the MPR121 using i2c protocol. I have the imp this is like the imp on steroids­čśĆ. Before I buy the board I want to make sure I can send the data with this component. I was SPI touch interface as well yet that tends to be slow.... The ability to capture this data to a website would be epic for a project I'm working on. Awesome build!

It should work fine. We've written demos using other Freescale I2C sensors like the FXOS8700 and FXAS21002. We don't have a driver for the MPR121 but it should be possible to port another driver from C or write one from scratch.
