Abstract The use of random numbers in small microcontrollers can be very useful and fun in robotic programming to yield different behaviors from the same robotic-control program. Due to limited memory, the lack of floating-point math capabilities, and the limited size of integers in some microcontrollers, the practical implementation of a software-based random number generator for a microcontroller is difficult. This paper looks at the generation of random numbers, and compares a variety of implementations on the 68HC11 microcontroller. A good implementation is chosen and the 68HC11 source code is provided that implements it. |
