Pointer Power/Pulley Driver Programs

for the CBL2

(The programs on this page generally do not work with the Original CBL. They do work with the LabPro, but do not include the ability to control a pointer in the LabPro's second dig/sonic port.)

Updated Sept. 29, 2005

 

Description

TI-83, TI-83 plus (including the "Silver Edition") and TI-84

POICBL2-- All 12 of the programs below zipped into one file.

POICBL2.zip
POIPIV -- Pivots the pointer by an angle, A, at angular speed, U
POIPIVF -- Pivots the pointer for time, T, at angular speed, U
POIPIVST -- Pivots the pointer S steps at angular speed, U
POIPIVW -- Continuously monitors input channel 1 and pivots the pointer at angular speed, U, while calculator function Y9 is not zero
POISWF -- Turns on a 12-V output for time, T
READ1 -- Measures the sensor value at analog Channel 1, and stores the result as "E"
READ2 -- Measures and records the sensor value at analog Channel 2, and stores the result as "F"
READ3 -- Measures and records the sensor value at analog Channel 3, and stores the result as "G"
LPOI-- A list of values generated by POISETUP, which specifies the pointer characteristics
POIPUT -- Rotates a supplementary servo motor to position, A
POISETUP -- Tests the pointer and records step size, default speed and maximum speed.
DCUINIT -- A utility program developed by Vernier Software (and distributed with their permission) which verifies correct communications between the calculator and the CBL.
