I would like to use a linbus tranceiver to boot up my pine64. When the IC senses traffic it wakes up and provides current for 20ms. When the board powered it has to set CSL/WAKE pin to high to have continues power. So how can I set a pin to high status when the board powered?
I dont want to use arduino or other microcontroller, it makes my board even more complex.
Thanks.
I may be overthinking it, but I'm imagining some sort of battery powered circuit with the receiver and a relay-- possibly optically coupled-- on a perf board that triggers the eular pins with the momentary voltage to wake your Pine, but that may be way over-engineered.
