Two Type D 9-pin connectors, CN6 (USART1) and CN5 (USART2) are available on the
STM3210B-EVAL board. The USART1 connector is connected to the RS232 transceiver
U10, and the USART2 connector with RTS/CTS handshake signal support is connected to
the RS232 transceiver U9.

Motor control

The STM3210B-EVAL board supports induction motor control via a 34-pin connector, CN14,
which provides all required control and feedback signals to and from a motor power-drive
board. Available signals on this connector include emergency stop, motor speed, 3-phase
motor current, bus voltage, heatsink temperature coming from the motor drive board and 6
channels of PWM control signals going to the motor drive circuit.
Special motor current sampling operation is enabled by setting jumper JP8.

CAN transceiver functions in standby mode when JP2 is set as shown below:
CAN transceiver functions in high-speed mode when JP2 is set as shown below:
CAN transceiver functions in slope control mode when JP2 is not fitted.
(Default setting)
CAN terminal resistor is enabled when JP3 is fitted.
Default setting: Not fitted
Motor control jumpers
Enables special motor current sampling operation when JP8 is fitted (PD2 connected
to PB0). The IO pins PD2 and PB0 are disconnected and can be used by the
daughter board when JP8 is not fitted.
Default setting: Fitted
JP12 must be open when the digital encoder signal comes from pin31 of CN14. It
must be closed when an analog signal comes from pin31 of CN14.
Default setting: Not fitted (open)
