Any changes to the front panel such as extra grease would initially be detected as finger press. However the counts look for a variation in the long term average so it should eventually compensate and greasy would be the new norm

Nice work Andy.

They were shifting to capacitive keypad technology just as I was leaving the Oil Industry (think unattended Truckstops).

I did hear that one thing that caught them out was dirt and greasy finger prints, so it's better to err on the safe side.

Hi Andy,

Great article! This would be excellent for building a large A4-sized calculator for the workshop : )

No need to clean hands before using it : )

Nice update.

It would be interesting to compare the TI and Cypress implementations for these types of systems.

It appears that TI has once again done a very good job of getting a good tool into the hands of engineers.

So did you overlay the materials across the BSWP or use them otherwise? [View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-bb7e2198-3fb3-483c-bb8c-09c0f6bf9090/contentimage_5F00_53.png:16:16]BTW, I have been plagued by software issues.
