Conclusion
The presented real application shows a typical system solution which was designed according to known
market needs.
The microcontroller used is based on a HC05 core which is able to control such a low dynamic
application and even more.The leftover memory space (>2kB) and performance capacity (free time is
~500
s each 1ms) are available for other application purposes. It allows one to design more
sophisticated control algorithms or implement some customer code to perform other tasks (keyboard
control, display control etc.) as well as serial communication.
But, a complete system solution depends not only on a microcontroller. Motor control design can be
drastically simplified using integrated parts, such as co-pack IGBT’s and integrated drivers, so that
a low-cost target can be achieved.
