- Push buttons are a very 90s feature. Today people expect non-touch touch points, like capacitive buttons. With the help of element14 and Texas Instrument's CapTIvate kit, I look how at self and mutual capacitive buttons work.

You're with element 14 now?
This will (likely) be the only element14 branded video on my channel. Any future (contract) work I do for them will be on theirs.
That is awesome news man. Well done!
You sourced a better documentation than companies provided.
Excellent
The subtitles are a great addition to all other “non-English” viewers. Because English is no not my main language, it’s more easy to understand if I enable the subtitles
Do you read them in English, or do you read the auto-translation?
Also I’ve learned a lot on your channel. Keep the good work!
I read in English, for a non-English speaker, read the subtitles in English helps a lot to understand some words due to the similar pronunciation
Looks like a winner for interactive museum exhibits -where the visitors press one or more buttons to select audio, video, or moving through information screens. Low MTBF pushbuttons cause a lot of failures.
Touch panels are easier to keep clean. Fewer places for dirt and bacteria to hide. But they aren’t as fun to press.
That pun xD
But it is just to make prototypes, how do you make a capacitance button in a real life project, I mean how to design the pcb, the controller, etc
This video is a tutorial on "capacitive touch" as a technology. The kit I showed could be considered a reference design for both designing a panel and implementing the microcontroller. As I said in the video, it is a nice way to learn about the technology before doing your own design.
Regarding design details, designing in the controller is following whatever instructions the manufacturer provides. As far as the panel goes, it depends on the end-product and requirements. In the case of TI, they documentation on all of the considerations. software-dl.ti.com/msp430/msp430_public_sw/mcu/msp430/CapTIvate_Design_Center/latest/exports/docs/users_guide/html/CapTIvate_Technology_Guide_html/markdown/ch_design_guide.html
I'm not touching it. Get it... I know I going.
Don't like capacitive touch as my zombie fingers have a 50/50 success rate :)
When you say the IDE works straight out of the box, I get the horrible idea that you mean "works straight out of the box on Windows".
I’ve installed it on OSX and Windows with no problem. Since it installed to OSX fine, I assume it would install to Linux. The “Captivate design center” is an entirely
different story.
