Hi all,

Has any one written a wrapper for the TTP229 capacitive 16 key Kepad libraries.

I have it working using the Arduino IDE but would like to use it with some B4R apps.

Attached are the library files that work with this.

Thanks

Thanks Erel,

I have also ordered another version. This one is advertised as a I2c bus but it isn't in the true sense of I2c.
It uses any 2 x IO pins with the library.

The library looks pretty simple and work well on the the Mega 2560. I Haven't quite got it working on a wemos yet.

Dear friends.
I tried using Wemos with the library posted above for TTP229 module but the Wemos exhibits : SoftWDT reset . Naturally the same result is obtained if I use inline C. Some library must be causing it. Gurus in forum please have a look!
