Board architecture
The STEVAL-IHM015V1 can be schematized as shown in
Figure 4.
The control board’s core is the ST7MC microcontroller with a dedicated peripheral included
to drive the 3-phase brushless motor.
The user interface is made up of four potentiometers (P1, P2, P3, P4) used to set
parameters related to the specific drive (see
Two push-button switches are also implemented.
●

Two LEDs (green/red), each related to a specific drive, are used to obtain a status on the
system (see
In normal functioning mode, the board is supplied by the V
supply connector (J6) is included on the board to feed the drivers and the microcontroller.
The board is supplied with a 2-Kbit EEPROM (M95020) connected to the micro by the SPI
bus. To enable the on-board EEPROM memory, the J2 jumper must be closed and the
debug feature must be disabled inside the firmware. J4 can be set by connecting a jumper
between pins 1-2 or 2-3. This setting is related to a specific drive (see
Two communication systems can be established with the microcontroller.

A Reset button for hardware resets.
A Start/Stop button used to start and stop the motor drive
ICC: used for programming/debugging purposes.
SCI: used for data exchanges through the SDI connector.
