B4R Library rTTP229 - Capacitive Keypad

Wrapper for ttp229-arduino open source project: https://github.com/arduino12/ttp229-arduino

It works with Arduino and ESP8266.

It can work in 8 keys mode or 16 keys mode.

Example:

Sub Process_Globals
   Public Serial1 As Serial
   Private ttp As TTP229
   Private d1pins As D1Pins
End Sub

Private Sub AppStart
   Serial1.Initialize(115200)
   Log("AppStart")
   ttp.Initialize(d1pins.D6, d1pins.D5, "ttp_KeyPressed") 'SCL pin and SDO pin
   ttp.Start8Keys
End Sub

Sub ttp_KeyPressed (Key As Byte)
   Log("Key down: ", Key)
End Sub
