Software
The software is written in C language, structured, and commented.
The main functions necessary for the proper operations of the evaluation board can be
found in the following .c files:
●
●
The follow .h files have to be included:
●
●
●
The option byte set in this project is shown in
Figure 5.
the overall code with the actual function is very small, almost 213 Byte.
The firmware parameters are set for the 7.2 DC brush motor, if the designer wishes to
change the motor he must change the firmware parameters in the file utility.h
Parameters:
●
●
we have another parameter Imin, it has been set to a value slightly higher than the current in
no load conditions, in order to be sure that the I safe is set to a value greater than the
minimum current drain by the motor.

Setting DC motor type multiplied by 10: i.e. 7.2 DC brush motor
–
Setting Isafe (maximum handling current in load conditions). The values must be
multiplied (in Amper) by 10. In the firmware the default values are 8 A so we have:
–
The default value is 3 A:
–
#define Motor_Type 72
#define Isafe 80
#define Imin 30
