James 1, 1 19 The data sheet says this is done as follows The Wake condition requires either that the system processor manually drive the SDA pin low for tWLO, or that a data byte of 0x00 is transmitted at a clock rate sufficiently slow that SDA is low for a minimum atsha2004 of tWLO.
That will determine how many bytes of 0x00 lnux to be written satisfy the required duration for wakeup. I am a bit of a nugget but always improving with Linux command line, so it is very advantageous for me to be able to see the command you are typing. You might have better luck on electronics.
