5. PXMC library.

5.1. Introduction.

PXMC is portable library to control various types of motors. Its main task or aim is to allow

user/developer to control different motors installed on different boards which can have also

different microcontrollers.

In more general we can say it is a multi platform code, initially written by Pavel Pisa for stepper

and brushless motors. Nowadays it can work for DC motors with IRC feedback, controlled by

H8S/2638 microcontroller. The basic concept of PXMC is shown on the following picture:

Fig. 5.1-1. The main concept of PXMC library.

A developer, who is represented here by a laptop icon, can use PXMC library to write programs

for different platforms and microcontrollers. At the some time he can choose interested motor

and then using proper functions and procedures he should be able to control different motors,

represented by car icons.

Of course in a real life, the above situation is not so easy. There are several conditions, which

must be fulfilled. First of them is, that there must exist a C/C++ compiler on the desired
