RS-232 connectors

USART1 (CN12) and USART2 (CN8) D-type 9-pin connectors are available on the
STM3210E-EVAL Evaluation board.
•
The USART1 connector is connected to the U7 RS-232 transceiver.
•
The USART2 connector with RTS/CTS handshake signal support is connected to the
U5 RS-232 transceiver. The USART2_CTS is multiplexed with motor control, it can be
enabled by setting the JP4 jumper. Refer to
5.9

Motor control

The STM3210E-EVAL Evaluation board supports three-phase brushless motor control via
the 34-pin connector (CN1), which provides all required control and feedback signals to and
from the motor power driving board. Available signals on this connector include emergency
stop, motor speed, three-phase motor current, bus voltage, heatsink temperature from the
motor driving board, and 6 channels of PWM control signals going to the motor driving
circuit.
The JP20 jumper selects one of the two synchronization methods for power factor
correction (PFC).
The I/O pins used on the motor-control connector (CN1) are multiplexed with some
peripherals on the board; either the motor-control connector or multiplexed peripherals can
be enabled by setting the jumpers JP3, JP4, JP11, JP15, and JP16 as described in

JP20 allows to have a PFC synchronization signal redirected to the timer 3 input capture 1
pin, and additionally to the timer 3 external trigger input. JTAG debugging is disabled when
JP20 is ON. The default setting is OFF.
JP2 must be kept OFF when the encoder signal is input from pin 31 of CN1 while it must
be kept ON when an analog signal is from pin 31 of CN1 for a special motor. The default
setting is OFF.
MC_EmergencySTOP is enabled when JP3 is ON. The pin PA6 is used as
SPI1_MISO when JP3 is OFF. The default setting is OFF.
MC_EnA is enabled when JP4 is set as shown on the
right (Default setting):
USART2_CTS is enabled when JP4 is set as shown on the
right:
MC_PFCpwm is enabled when JP11 is OFF. The pin PB5 will be used as
the interrupt input from the temperature sensor when JP11 is ON.
MC_UH or I2S_MCK are enabled when JP15 is OFF. The pin PC6 is used
as Smartcard_CMDVCC when JP15 is ON.
MC_VH is enabled when JP16 is OFF. The pin PC7 is used as
Smartcard_OFF when JP16 is ON.
