Pointer Driver Programs

for the SVP-A board and the LabPro

Except as noted, the first set of programs on this page also work with the CBL2 . They generally do not with the Original CBL.

The second set of programs below are unique to the LabPro, adding the ability to control a second pointer in the LabPro's Dig/Sonic Port 2. Click here to jump to the supplementary files for the LabPro's port 2.

Description

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

POILP1-- All 11 of the programs below zipped into one file.

POILP18.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"
READ4 -- Measures and records the sensor value at analog Channel 4, and stores the result as "H" (Neither the original CBL nor the CBL2 has an analog channel 4)
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.
