This program will allow you to use the TI CBR as a sonar device with a TI-89 to plot the distance of objects from a point while the CBR rotates around this point.
Required data are L1 and L2 (both from the CBR), angle covered during scan (in radians), and the direction of scan (either left or right).
Note: cbrsonar.89p is the program file that is executable on a TI-89 and cbrsonar.txt is the plain text version of the code.
