Software? We'll do that ourselves
Three examples explained
Elsewhere in this issue is an article for a stepper motor driver. This article describes the demonstration software for this circuit. We explain how these programs came about and find that there are several ways of achieving our goal.We have purposely kept the software for the stepper motor driver as simple as possible. This makes it easier to follow and allows you to use it as a basis for your own software. Examples are given in assembler as well as C. These two examples are meant for use with the 89S8252 Flash Microcontroller Board (Elektor Electronics, December 2001). The third example is in Visual Basic and works on a PC. This lets you generate the required signals without the use of special hardware.
