Hi,

here's the product folder page for the capacitive touch boosterpack:http://www.ti.com/tool/430boost-sense1, it has more information (hardware, firmware, capacitive touch library, gui, etc.) on the tool.

The page also contains the link to the zip file containing source code as well as other HW/SW documentation for the board.

You can find more examples with the library on the link provided by the other e2e post.

Regards,

Dung

hello,

thank you for helping.

I have downloaded the source code but I have a doubt in the following code lines in the CaptouchActiveMode() function:-

 if (wheel_position < 0x08)
 {
 wheel_position += 0x40 - 0x08;
 }
 else
 {
 wheel_position -= 0x08;
 /* Adjust wheel position based: rotate CCW by 2 positions */
 }
      
 wheel_position = wheel_position >>2; // divide by four

how the wheel position is determined please explain...
