I'm not sure what you're asking about and certainly not in the last section.
To get started with Knockbang, here is what I do:
In _TinyISP_BuildOptions_h i put these lines:
#define RELAY_SERIAL_ENABLED 0
#define RELAY_KNOCK_BANG_ENABLED 1
And in TinyISP I comment this:
//#include <SoftwareSerial.h>
Then I upload this sketch to the ATtiny85:
#include <TinyDebugKnockBang.h>
int x=0;
void setup( void ) {
Debug.begin( 250000 );
}
void loop( void )
{
Debug.print("Test-");
Debug.println(x++);
delay( 1000 );
}
Open the serial monitor @19200 and enter !
