Need Help with Tapes

[The Artful Dodger]

Hello, all:
I have been spending some time with the code for several instruments which implement tapes, in my case, speed tapes, and, while I am very familiar with coding in other languages, the LUA sequence of execution in these pieces of code has me befuddled! LUA seems to execute functions which I cannot determine how or where they are called!
I have looked but cannot find any videos or text instructions on exactly how to go about creating a tape, be it speed, altitude, or any other similar construction. If there is such a tutorial, I would greatly appreciate a link to any information related to this topic. :>D

Thanks, in advance,

Sparky

Hi.

It can be done. I have done it more by fluke than coding science.
Let me be clear that i am talking to using canvass and not images. In other words not using the moving carrot feature. Or the simple running image feature.

Tapes / running image/ running text are quite challenging and can be hard to grasp. The easiest way to start is copying script from an existing instrument, like the free Aspen EFD1000.

Hi, Keith:

I want to make absolutely certain that you meant to implement a tape feature (speed, altitude, etc.) using the canvas functions rather than the running text/image functions mentioned by Ralph? I just wanted to make sure I understood before I leapt in that direction!

Thanks in advance.

Hi Sparky.

Yes I talk to using canvas function.
