graphical errors with KhiCas

→ **MyCalcs** profile · by **DaManDaMythDaLeg** » 07 Feb 2021, 10:05

i just want to know if i'm the only one who is unable to plot graphs, or open any of the Xcas things without some crazy graphical errors

pretty much anything outside of the basic lua has glitches, and any commands that *should* cause a graph or plot or whatever to show up have the same issue

(ndless v4.5.0, everything up to date, hardware revision AC)

I'll try to post some pictures later, if i remember

a more detailed description of the errors

anything that (i think) would be text, the pixels are scrambled, and there are 3 rows of duplicates

the screen seems to be rotated 90*,

yellow bar on the left, blue bar on the right

the screen is somewhat navigatable, as in, I can see the screen react when I press buttons, however, it's almost impossible to discern what any of it means

I have a few guesses, but since I can't really look into the source with the software I have right now (that being, nothing but a hex editor and notepad), i can't confirm any of my suspicions
-the program is trying to access a picture that doesn't exist; I think this may have something to do with it because I saw almost the exact same thing occur when I downloaded nTris and opened it (without moving any of the background images over to the calculator)

-some sort of hardware incompatibility

-something else ... I'm not very knowledgeable in this field so I really don't know what's going on

Some pictures would surely help.
Can you specify which Nspire you have ? (CX, CX CAS, CX II, CX II CAS, CX II T...) and the final part of your serial number (bottom of the rear side) X-###### ?

Can you provide more information? First, are you running khicas.tns (KhiCAS shell) or khicaslua.tns (Lua interface)? (I recommend using the first one.) Then, an example of commandline that raises the problem.

khicaslua.tns
khicas.tns has the same issue described previously

it's the top of the rear side for me, is that bad?

Yes that's fine. N-0118AC means factory N, manufactured in january 2018, revision AC.

also, while I have some peoples attention,
KhiCas has some issues with trig, I recommend letting it use the double angle trig identities (if that's possible)
