Board architecture
The STEVAL-IHM010V1 can be schematized as in
Figure 3.
The heart of the control board is the ST7MC microcontroller which is provided with a
dedicated peripheral to drive the three-phase brushless motor.
The user interface is constituted of four potentiometers (P1, P2, P3, P4) which are used to
set parameters related to the specific drive, see
Two push buttons are also present:
●
●
Two LEDs (green and red) provide information about the status of the system. Their
behavior is related to the specific drive, see
In normal functionality it is expected that the board is supplied by the MC connector, but for
stand-alone operation, an auxiliary supply connector for 5 V power supply is included on the
board. Providing more than 5.5 V through this connector may cause permanent damage to
the device since no over voltage protection device is present.
The board is supplied with 2 Kbit EEPROM (M95020) connected to the micro by an SPI bus.
To enable the onboard EEPROM memory, the jumper J2 must be closed and the debug
feature must be disabled inside the firmware.
J5 can be set by the user by connecting a jumper between pins 1-2 or 2-3. This setting is
related to a specific drive, see
Reset button for a "hardware reset" of the board.
Start/stop button used to start and stop motor driving, see
demonstration.
