Greetings all;
Trying to setup a lut5 to block false errors. setup with 3 inputs.
I already have a oneshot setup to ignore the power up momentary false as
the
drivers are powered up only when F2 is active on most of my machines.
But that also gives a true when in-2 is false
normal operation should have a true output only when in-2 is true, and
either in-0 or in-1 goes false.
The lut5.function= 0x80 doesn't seem to be correct.
I need a true only for in-2 = true, and either in-0 or in-1 goes false.
All other conditions s/b false.
What should the function param be be set to?
If you set function=0x80, out is only true when in-0=1, in-1=1 and in2=1.
I think you need function=0xE0 with one 'edge' on in-0 and in-1 to detect
'goes false' if I understand your problem correctly.
Furthermore I think that would better fit into the forum in the HAL section.

I don't "do" forums, Hans. Too many pw and such to remember when the wet ram is
87 yo.
And I have been banned for asking tech questions that are considered off topic.
Everything I have done on the pi has been done in a vacuum because I had the
chutzpah
to ask about a real time kernel and my posts to the raspi forum now go to a
black hole.
That includes my own method to install the kernel I built on a different
booting system,
a u-boot. And the install tarball is under 30 megs without gzip in the room. To
me, the
pi's are great, but the foundations attitude about what they can be used for,
sucks about
10-33 torr.
Just putting my thoughts down on electric paper often leads to a solution, see
my last
msg to Andy. :o)>
Take care and stay well Hans, and thank you.
Cheers, Gene Heskett.
