TouchTest example to use polling instead of interrupt #21

Open ImpulseAdventure opened 5 years ago

First off, great work on the library Paul!

Change

Modified the default constructor in TouchTest.ino to use polling mode

Description

TouchTestIRQ.ino demonstrates the use of the interrupt event APIs
I believe TouchTest.ino was originally intended to demonstrate the use of the polling APIs
However, the current TouchTest.ino invokes the TIRQ_PIN constructor (!=255) which appears to initiate the ISR handling mode
The existing default may potentially introduce confusion for some users, hence the proposal to adjust the constructor mode

thanks
