Texas Instruments TI 84 Plus

Version Française

A good graphic machine! It is running DATE in its biorythm subroutine.

What's in the box Development tools My programs

A very powerful and friendly user calculator. For simple machines, I really prefer Casio than Texas (for example the Casio 2D better than any TI 30), but when talking about graphic calculators, Texas has no competitor in the japanese firm.

The super graphic:
  1. Processor Z80 clocked at 10MHz
  2. 24kb RAM and 480kb of flash memory
  3. Pascal-like programmation, Z80 assembler
  4. USB link to a PC, link between two calculators.
Bad points:
  1. I can't find any...
Development tools:

First the program editor TI Editor. Writing a program is made fast and easy. An icon allows you to tranfert your creation directly to the calculator from within the editor. On the left you can see the whole function list that can be accessed with few clics.
TI Debugger helps you test your program on the PC. You save a lot of battery power avoiding many transferts.
You can add tracing instructions or directly debug at a machine language level, most of all if you write a flash application.
Zilog offers his Z80 assembler ZILOG Developer Studio. The library gives acces to the internal functions of the calculator. Then you can prepare your "mini programs" to be executed by Asm() or, better, write a whole flash application.
TI Connect manages the calculator memory as a peripherial storage. You can up/download programs, data, flash applications and update the OS. The essential tool!
