I'm not sure whether I'm right in this forum or not, but here's my problem:

A few weeks ago I installed a new sound card for my Windows 7 64-bit computer and suddenly the graph link didn't work anymore. I looked into the device manager and it says the driver can't be verified to be signed or something. I never had this problem before.
Every time I plug in the cable, after it tried to install software and says it failed. Reinstalling/updating driver leads always to the same problem, it says the driver is the newest version.
Booting without driver signature is possible and it shows up the device is working correctly, but TIConnect is acting up and doesn't find the device.

I'm using TIConnect with a TI 83+.

Wow, that looks awesome for a chalkboard drawing ! 

I think it may help if you are more precise - can you attach the code (if it isn't lost), did any errors occur, was it while compiling, backing up or execution?

I think you'd have to write your own routine for that.
It's quite slow but you could copy the last 8 rows of the buffer to another buffer, shift that and copy it back.

example with L6 and L3 (if you use them for something else you'd have to use other buffers)

Is it really THAT simple? I'm gonna try that out now. * MGOS types it in the calc and wonders how easy that was.

Thanks a lot.

Hey, for my Maths I have to make a program to calculate increasing and stuff, and it needs to have recursive sequences as well.
The problem is, I can't find the right commands and variables in the program editor.   
How would I store a recursive equation ( u(n) = u(n)*2 as an easy example) into u, v or w?
And how can I set the start ( uMin and u(nMin) = {x} )? 

I hope there is somebody who can help me.

No, It only works in TI-Basic, but with what you can do in axe I can't see any use of the Horiz command in axe.

Since this is on an axe board, I think he wants to do it Axe - and there is no Horiz command.

Oh, I totally overlooked that.

Wow, this looks amazing so far. Incredible what you can do with just TI-Basic. Good Luck!

Also, make sure to add the parentheses in the square root bracket, because axe will compute it like this:

for me the same, you should finish it. Don't forget "if-then-end" and the "for" loop. Also you should add a note that "remainder" and "Zquadrant1" aren't accessable on a TI-83+.

Ok, thanks for the explanation. That makes it a lot clearer for me. So I will have to use other key combinations to make sure nobody accidentally presses them like I did.

I'm having trouble with getkey(49) (graph). It returns one each time the key down and [right + zoom or left + trace] are pressed (all three the same time)

Monochrome is best and 3-level gray is ok as well. But 4-level isn't possible
