Control of toy car model on freeway
Author: Ondřej Penc
This work describes the
development of a selfdriven slotcar riding on a circuit, from
analysis of track pannels, through assembling of an electronic part
to programming and testing. The slotcar demonstrates function of used
components especially sensors, driving elements and function modules
of microcontroller \mbox{MCF51JM64}. The analysis of track pannels
was used for a design of sensors, power supply and for simplification
of mapping of the circuit. An h-bridge MC33931, which works in
four-quadrant mode was chosen as a~driving element to a motor. A
signal of an accelerometer was filtered and problems with delaying
had to be solved. The accelerometer was good for measuring
centrifugal acceleration through mapping and measured data agreed
with the premises. In this aplication an SD card was used as a
storage device for collected data from race and also USB tranceiver
which enabling connection of microcontroller and standard computer.
USB interface is used for programming of the microcontroller by the
function called
Bootloader instead of standard BDM iterface.
