We're glad you came by, but you might find what you're looking for elsewhere. TI-Basic Developer is not the site it once was. While its information on commands and other calculator features remains almost second-to-none, its forum, archives, and even hosting service, Wikidot, have been decaying for years. The calculator community would love to see what you're working on, or help you in your next coding adventure, but TI-Basic Developer is no longer the place to do it. Instead, you should head over to Cemetech (primarily American) or TI-Planet (primarily international). Both are active, well-established forums with their own archives, chatrooms, reference material, and abundant coding tools and resources. We'll see you there, we hope. |
The picture to the right top contains the value returned by getKey for each keypress. The picture is organized so that the key codes are placed where they would be on the literal calculator. You should note that the [ON] key (the key in the bottom left corner) has no key code, so you cannot check for nor disable it.
If you look at the key codes, you will probably notice that they actually follow a pattern: a key is represented by putting its row and column together. For example, the [ENTER] key is row 10, column 5; therefore, its value is 105. The up, right, and left arrow keys are assumed to be in the second row, and the down arrow key is in the 3rd row.
In case you want to know the key codes while using your calculator, here is a simple program to use:
:Repeat Ans=105
:getKey
:If Ans:Disp Ans
:EndThe picture to the right bottom contains the value returned by the real(8 command when using xlib. The key placement is somewhat disorganized, but consistent for the most part. The [ON] key will return a value, according to the tutorial, but due to the [ON] break inherent to TI-Basic, it will not be returned.
