It seems likely that this is the same as #108.
If so, it's fixed but there hasn't been a release since the fix went in.
Yes, it's same.
@lulf Should I make a release based on this merged PR plus other stuff?
I went through example regard using nonblocking display — https://github.com/nrf-rs/microbit/blob/main/examples/display-nonblocking/src/main.rs.
I noticed that some LEDs shine very dimmly in their core that should not. This is permanent for pattern being displayed. Since I verified using blocking API there is no issue with LEDs on this, I suppose some wrong.
My unqualified guess is there is some interferrence regard timing.
From doc.
I tried some interrupt priorities and RTC0 frequencies variations but issue is resistable to this.
Sample of displaying letter E; RTC0 with 100 prescaler, NVIC priority 32, TIMER2 NVIC priority 64
So I wonder if there is bug somewhere seeking for remendy.
