STEVAL-IHM022V1 STM32-based dual
motor FOC drive demonstration board
Introduction
The STEVAL-IHM022V1 demonstration board is designed as a dual motor field-oriented
control (FOC) development platform for STMicroelectronics’ ARM Cortex™- M3 core-based
STM32F103ZE microcontroller. The board features full speed USB 2.0 and CAN 2.0 A/B
compliant interfaces, 2 I2S channels, 2 I2C channels, 5 USART channels, 3 SPI channels, 2
DAC channels, internal 64 KB SRAM and 512 KB Flash memory, and JTAG and SWD
debugging support. The board is designed to implement multiple motor control (up to three
MC connectors are available) and offers an advanced user I/O interface (LCD QVGA display
and joystick key). Extension headers make it easy to connect a daughterboard or wrapping
board for specific applications.
The demonstration board can be ordered through order code STEVAL-IHM022V1.

1.1 Power supply
The STEVAL-IHM022V1 demonstration board is designed to be powered by a 5 V DC power
supply and to be protected from incorrect power plug-in events by a PolyZen U5. The
demonstration board can be configured to use any of following three power sources:
●5 V DC power adapter connected to power jack CON12 (DC5V on the silk screen).
Alternatively, 5 V DC can be provided through 2-way screw connector CON13 (aux
DC5V on the silk screen) when using a generic DC power supply
●5 V DC power with 500 mA limit from the type-B USB connector CON11 (USB B on the
silkscreen)
●5 V DC power from daughterboard extension connectors CON1 and CON3
The power supply is configured by setting jumpers JP9, JP10, JP11 and JP12 as described
in Ta b l e 1 .
The D5 LED is lit when the demonstration board is powered correctly.
1.2 Boot options
The STEVAL-IHM022V1 demonstration board can be booted from:
●embedded user Flash
●embedded SRAM for debugging
●system memory with boot loader for ISP
The boot option is configured by setting switch BOOT0 and BOOT1 as described in Ta bl e 2 .

Jumper Power supply option Setting
JP9,JP10,JP11
For power supply from power jack CON12 or 2-way screw connector CON13,
place a jumper on JP9 only (default setting).
For power supply from the daughterboard extension connectors CON1 and
CON3, place a jumper on JP10 only.
For power supply from USB connector CON11, place a jumper on JP11 only.
For power supply from power supply jack CON12 to both the STEVAL-
IHM022V1 and the daughterboard connected on CON1 and CON3, place
jumpers on JP9 and JP10 as shown (the daughterboard must not have its own
power supply connected).
JP12 Enables consumption measurement of both VDD and VDDA.

1.5 Serial Flash
A 64 (or 128) Mbit serial Flash is connected to SPI1 of the STM32F103ZE. SPI1 pins NSS,
MISO, MOSI and SCK are multiplexed with other peripherals, such as motor control timers
and JTAG debug. Ta bl e 4 lists the jumper configurations for enabling SPI1 peripheral
communication with serial Flash.
1.6 CAN
The STEVAL-IHM022V1 demonstration board supports CAN 2.0 A/B-compliant CAN bus
communication based on a 3.3 V CAN transceiver. High-speed mode, standby mode and
slope control mode are available and can be selected through JMP2.

1.7 RS-232 connectors
Two D-type 9-pin connectors P3 (USART1) and P2 (USART2) are available on the STEVAL-
IHM022V1 demonstration board. The USART1 connector is connected to RS-232
transceiver U10, while the USART2 connector with RTS/CTS handshake signal support is
connected to RS-232 transceiver U9.
1.8 Motor control connectors
The STEVAL-IHM022V1 demonstration board supports control of up to three 3-phase
brushless motors via three 34-pin connectors: CON8 (MC main), CON9 (MC sub1) and
CON10 (MC sub2). Each connector provides all required control and feedback signals to
and from the motor power-driving board. Available signals which are common to all these
connectors include:
– emergency stop
– motor speed
– 3-phase motor current
– bus voltage sense
– heatsink temperature sense from the motor driving board
– 6 channels of PWM control signals to the motor driving circuit.
For third-motor control connector MC sub2, the 6 PWM channels can be derived either by
using two general-purpose timers working in tandem, or by using just one GP timer plus
additional external circuitry for complementary PWM signals. An auxiliary connector (MC
sub2 Aux) is available on the demonstration board to connect a daughterboard for additional
logic.
The MC main connector features additional sensing signals (AC bus, DC bus and input
current) for PFC (power factor control) controller management.
The I/O pins used on the motor control connectors are multiplexed with some peripherals on
the board. Either motor control connectors or multiplexed peripherals can be enabled by
setting the jumpers, as described inTable 6: Motor control-related jumpers.

to the timer 3 input capture 1 pin, in addition to the timer 3
external trigger input.

1.9 USB
The STEVAL-IHM022V1 demonstration board supports USB 2.0-compliant full-speed
communication via a USB type B connector (CON11). The board can be powered by this
USB connection at 5 V DC with a 500 mA current limit. USB disconnection simulation can
be implemented by disconnecting the 1.5 k pull-up resistor from the USB+ line. The USB
disconnection simulation feature is enabled by setting JMP1.
JP4
A jumper on JP4 should be fitted to enable filtering when an
analog signal is present on pin 31 of CON8 (e.g. a signal
generated by a tachometer). It should be not fitted if a signal
from an encoder is used.
Default setting: not fitted
JP6
A jumper on JP6 should be fitted to enable filtering when an
analog signal is present on pin 31 of CON9 (e.g. a signal
generated by a tachometer). It should be not fitted if a signal
from an encoder is used.
Default setting: not fitted
JP7
A jumper on JP7 should be fitted to enable filtering when an
analog signal is present on pin 31 of CON10 (e.g. a signal
generated by a tachometer). It should be not fitted if a signal
from an encoder is used.
Default setting: not fitted
J1
J1 swaps timer 8 channel 3 PWM outputs between pin 11 (MC
WH) and pin 13 (MC WL) of MC sub1 connector.
Default setting: as shown.
J2
J2 swaps MC sub1 bus voltage and MC sub1 currentB analog
signals between pin 44 (ADC12_IN14) and pin 20 (ADC3_IN6)
of the STM32 MCU.
Default setting: as shown.

1.10 Development and debug support
The two debug connectors available on the STEVAL-IHM022V1 demonstration board are:
●CON6 - a standard 20-pin JTAG interface connector that is compliant with ARM7 and
ARM9 debug tools.
●CON5 - a SAMTEC 20-pin connector (code FTR-110-01-S-D) for both SWD and trace
that is compliant with ARM CoreSight debug tools.
1.11 Display and input devices
The 240 x 320 TFT color LCD and 4 general-purpose LEDs (D1, D3, D3, D4) are available
as display devices. A 4-direction joystick with selection key (U1), a general-purpose button
(SW3), a wakeup button (SW2) and a tamper detection button (SW1) are available as input
devices.
Jumper JMP3 should be kept open to enable wakeup button SW2, which shares the same
I/O with motor control connectors MC main and MC sub2.

Jumper Description
JMP1
The USB 1.5 k pull-up resistor is always connected to the USB+ line when
JMP1 is set as shown (default setting):
The USB 1.5 k pull-up resistor can be disconnected by software from the
USB+ line when JMP1 is set as shown. In this case, the USB
connect/disconnect features are managed by standard IO port PD8.

2.4 Auxiliary motor control connector CON14
For a third-motor operations, there is no dedicated advanced timer peripheral. In this case,
the 6 PWM signals needed to drive a 3PH power stage can be derived either by using two
GP timers (TIM2 and TIM4 working in tandem), or a single GP timer plus additional external
circuitry, plugged into the CON14 connector, to generate the remaining 3 complementary
PWM signals.
