Separate parameters for each GPIO pin

[vranisimo]

Hi,

I am trying to achieve a dormant mode that will wake up when water floater (in the pool) changed its state (0 to 1 or 1 to 0).

So basically, I would need a dormant mode that waits for:

• a level change (high-to-low + low-to-high) on the same pin

OR (as an alternative)

• high level on PIN1 and low level on PIN2 at the same time

The current API allows us to add multiple GPIO pins but with the same parameters for waiting logic.

Do you think it is technically possible to implement a different logic for each pin, due to board limitations and a way how dormant mode works?

Hey @vranisimo,

I know my answer is long past overdue and that you've probably moved on to other projects, but I actually got around to implement the changes you proposed (and discovered an major bug at the same occasion).

There is now a new method called dormant_with_modes that supports both the possibilities you mentioned.

Here is the excerpt from the updated README:

The lower-level dormant_with_modes allows to set different wake-up conditions for each individual pin.

For convenience, lowpower exposes the four possibles wake-up conditions as the constants EDGE_LOW, EDGE_HIGH, LEVEL_LOW and LEVEL_HIGH.

Example:

import lowpower

DORMANT_PIN1 = 16
DORMANT_PIN2 = 17

print("before dormant")
lowpower.dormant_with_modes({
        DORMANT_PIN1: (lowpower.EDGE_LOW | lowpower.EDGE_HIGH),
        DORMANT_PIN2: lowpower.LEVEL_HIGH,
})
print("after dormant") # only print after receiving the correct signal on one of the pins

Cheers!
