This tutorial shows you how to deal with the Shift extension!

Note

To use this:

#define EBOARD_SHIFT_REGISTER 0x1

Pin extensions

It is possible to extend the amount of available pins via SN74HC595 Shift-Registers. Connect them like this:

Note

it is possible to extend the amount of shiftregisters. This version of eBoard supports up to 32 (64) additional pins.
But it is possible to connect even more!

To assign this pins with the special values you can use the SoccerBoard::power() [SoccerBoard::powerOn(); SoccerBoard::powerOff()] Syntax with pinIDs >99 [100 => 0 etc.] This is an example-program:

#define EBOARD_SHIFT_REGISTER 0x1
#include <eBoard.h>
//manual: '#include "/path/to/eBoard.h"'

SoccerBoard board;
int main() {
    board.powerOn(100);
    return 0;
}

This will set the Output value of Pin 100 (Q0 on the first SN74HC595) to HIGH.

Hardware specific

• It is possible to set a Data of a single Pin with shiftSingle();
• It is also possible to shift the modified store_bits with shiftAll();

store_bits can be modified via bitSet()/bitClear() or long assignment (like = 1000);
