Power OneWire salve

[guiguid]

Hi,
you made a POWER class that control power of internal composants.
Is it possible to extend this class to drive slaves like OneWire ones ?

Power consumation of OneWire salve can be reduce by disconnecting the pull up resistor.

example :
D1 ------|==R==|-------
D2 --------------------------+-------
' ONEWIRE SLAVES
GND --------------------------------/

In this way, D1 & D2 can be put in High Impedance mode in order to preserve power when ONEWIRE bus is not need.

the class may include a delay when power on the ONEWIRE bus to let some time to initialize the slaves.

my 2ct

sorry, you can close :
CosaVWIsender.ino
// Virtual Wire Interface Transmitter and Power Control pins
VWI::Transmitter tx(Board::D2, &codec);
OutputPin pw(Board::D1);

sincerely sorry.

ok!

This could be added to the CosaVWItempsensor.ino example sketch. I will include this.

Cheers

Updated the CosaVWItempsensor example sketch to allow power control of the 1-Wire pullup.
