requiresBurnInProtection how toimplement

_psx_ over 5 years ago

In not amoled display onUpdate() or oPartialUpdate is called every second.

How to implementing drawing then screen require requiresBurnInProtection?

Should i start timer? Should I add a special layout named AlwaysOn?

How to update time every minutes?e

Does system remove layout when enter into low power mode?

The whole key is if you are in low power mode and requiresBurnInProtection is true, you ate limited to 10% of the pixels are on and no pixel can be on more than 3 minues, no matter how you do it

I've already found solution

Check with "view heat map" in the sim...

the docs say, no pixel must be enabled for more than 3mins. How often is the screen redrawn - once a minute? Is it save to use a 3 position layout without any overlapping pixel?

Yes. Every minute.

my always on started to run bad , off course it run 3 minutes, even 8 hours but about 30000s I get error

so I have next questions:

1. What does exactly mean (according to https://developer.garmin.com/connect-iq/connect-iq-faq/how-do-i-make-a-watch-face-for-amoled-products/):

No more than 10% screen pixels can be on
In what period? For one minutes?
No pixel can be on longer than 3 mins
In what period? If pixel is on for 1 mins then off for 1 min and on for 1 min is it ok?

My code is simple

dc.clearClip();

dc.setColor(BLACK, BLACK);

dc.clear();

... write every first 5 minutes the same drawing moving "down" then move to top and again

So if it run 3 minutes, 8h why there is "error" in 9th hours?

I don't have venu so I don't how it''s look on device:

- Does user see any error or only black screen shows?

- If user wakes up device after "error" and it goes to sleep again does system show my always on or like in onPartial (after onPowerBudgetExceeded) system not cal onUpdate for this version?

Up to 10% can be on at a time, If that ever happens, you get the error in the hear map right when it happens.

the 3 minutes is 3 minutes on (not black). If that pixel is on for a minute, off for 1 minute and then back on for a minute, that's fine.

Ok, I've found error in my code, I start draw white background, sim heat map shows error but on simulator was still black.

I think it should be corrected because heat map should stop after drawing on sim not before because developer think "sim screen is black and I see something is wrong on heat map, what's going on?"
