A resistor color band calculator for the TI-84 Plus CE
Supports 4, 5, or 6 band resistor color codes
Currently only tested for the TI-84 Plus CE. Written in TI-Basic and uses color display functionality; if your TI calculator supports this then there is a chance it will work for you as well.
- Download the RESCOLOR.8xp file.
- Load RESCOLOR.8xp onto your calculator using the TI Connect CE (TM) application from Texas Instruments. It is recommended that you load the file into the archive and not the RAM, so that it is persistent.
- The file will appear under the prgm button.
Alternatively, the Basic program file is provided, from which you can copy and paste into the TI Connect CE (TM) program editor.
Use the up and down arrows to scroll, and Enter to select.
Select the desired calculator (4, 5, or 6 bands), or Quit.
Use the left and right arrows to select the band you wish to set. A black dot above the band indicates the selected band.
Use the up and down arrows to change the color of the band. The letter below the band stands for the color of the band, and the text in the bottom left corner of the screen indicates the full name of the color of the current band. This is for additional clarity, as because of the calculator's limited color selection some colors are reused (for example, both gold and orange use the TI display's orange color).
Press Enter to confirm your color choices. The calculator will display the resistance, tolerance, and (for 6 band resistors ONLY) the PPM. Note that at this time, not all invalid inputs are properly handled, and may cause an error.
Press Enter to return to the Main Menu
Quit exits the program, clears the drawn items, and resets the graph settings to the TI default.
Some invalid inputs are not properly handled, and cause an error, stopping the program. This is never an issue if resistor color codes are inputted correctly.
