TTP226 module touch panel serial mode library for Mysensors?

Re: How To: Make a Simple/Cheap Scene Controller (with video)

Do we have any serial mode library?

[AWI]

@vikasjee no need for a library there. The thread contains an example for using the TTP226.

@AWI I need to use the Serial Mode ( 2 pins ) in TTP226 module instead of Direct Mode which requires ( 9 pins) on Arduino with Interrupt enabled on 8 inputs. Hence the request for the Serial Mode TTP226 library

@vikasjee sorry I forgot to attach the link to the thread where the serial interface is used. This piece of code is sufficient:

// fetch serial data, store in keyState
int fetchData(){
    digitalWrite(SCL_pin, LOW);                             // get first bit
    delayMicroseconds(100);                                 // allow for stable input
    digitalWrite(SCL_pin, HIGH);
    for(int i = 0; i < keyboardSize; i++){                  // read all keys 
        keyState[i] = (digitalRead(SDA_pin) == LOW) ;       // set key if pressed
        digitalWrite(SCL_pin, LOW);                         // get first bit
        delayMicroseconds(100);                             // allow for stable input
        digitalWrite(SCL_pin, HIGH);
        delayMicroseconds(100);
    }
}

@AWI Thanks for the piece of code. Now i can see where i was wrong! Let me run it... this seems to be missing the interrupt part though. I will try using DV on Int2...
