This is a library you run on your FPGA.
When you are making a circuit board, you can make a big pad of exposed copper and connect it to one of the I/O pins on the chip.
You can then use that pad as a button, instead of buying a button and soldering it to the board
- exmadscientist 5y agoBut don't do this unless you have to, since a button is a hundred times more reliable and easier to use. (Buttons actually provide tactile feedback, for one....)
- emteycz 5y agocan't you provide electrical feedback?
- exmadscientist 5y agoIn terms of stuff lighting up? Sure. In terms of something the finger pressing the button can feel, no. It's completely impossible with a cap-touch button, a problem also shared with piezo buttons. And a major reason they are very annoying to use.
- jcun4128 5y agoI feel like I saw this concept recently (big exposed conductive pads) as a way to generate random numbers (Ben Heck's recent YT video about his lanyard game).
