Hi!
Some beginners help please.
My project basically lights LEDS. I want to have a switch that when pressed, it hibernates. When pressed again, it 'wakes up'.
In the manual (P57) for 'Hibernate', regarding best low power consumption, it advises:
"ensure that no outputs are being actively driven..."
I don't understand what this means?
Does it mean that if I am currently driving LEDS, I must switch them off before calling the 'hibernate' routine?
Also, from the point of view of low power consumption (and general practice), does it make a difference if one 'side' of my LEDs are going direct to '+' and the other side of the LEDS go (via resistors) to 28X1 outputs which go low to switch on the LEDs (this is what I am doing). Or should one side of the LEDs go to '0v' and I should be using the 28X1 outputs to go high (via resistors) to power the LEDs?
Help/comments appreciated
Thanks
Mik
