Re: Display update difference between DM41X and HP41
Differing results are always interesting...
Can folks please report a few additional details about their configuration when they do/don't see the delay, such as:
a. Display mode (SI vs. Stack)
b. Modules loaded (initially just yes or no)
c. Digit display setting (e.g. Fix-9, Sci-2, etc.)
d. Other non-vanilla things in your own setup
Thanks

Re: Display update difference between DM41X and HP41
Initially :
a. SI
b. No module loaded
c. Fix 9
d. Slow mode
After testing, still no issue with Stack display mode or Fix 4, or Fast mode.

Re: Display update difference between DM41X and HP41
It happens in both SI and Stack Mode
Yes. Modules Loaded
Initially I was in FixALL (Warp Core) Mode.
I switched back to FIX 4 and it still happens.
HEPAX is the only Non-Vanilla thing in my configuration.

Yes

Fix-6
d. Other non-vanilla things in your own setup
SandMath was loaded (amongst others) with full 'mkeys' key assignment, which for those who don't know it, is pretty resource heavy as it provides access to far more than the usual single assignment per key. But even with that in the background the test program ran without any glitches.
Re: Display update difference between DM41X and HP41
Its looks like it is the ir printer module.
Bob your comment about the modules made me think, I was testing IR functionality on the 41X and the 42 and this was the thing I recently changed.
I don't have a real ir module to compare.
With the module plugged its slow and without it acts normal

Re: Display update difference between DM41X and HP41
My tests on the 41CL Below, were done with a real 82242A IR Module plugged in => Normal Behavior.
With the "Thermal Printer" Module unplugged from the DM41X => Normal Behavior.
I think you've found the culprit!

Re: Display update difference between DM41X and HP41
HEPAX don't change anything.
But with the THERMAL PRINTER module the bug appears.
