2.9 RS-232
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 RS-232 transceiver
U10, and the USART2 connector with RTS/CTS handshake signal support is connected to
the RS-232 transceiver U9.
2.10 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.
2.11 Smartcard
The STMicroelectronics smartcard interface device ST8024 is used on the STM3210B-
EVAL board for asynchronous 3V and 5V smartcards. It performs all supply protection and
control functions based on the connections with the STM32F10X microcontroller, which are
listed in
Table 8 . An example of smartcard is provided with the board called GSM file system
sample. With this board, you can play basic commands, select a file and do simple
read/write operations to become familiar with this interface and the ISO/IEC 7816-3
protocol.

Jumper Description
JP8
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
daughterboard when JP8 is not fitted.
Default setting: Fitted
JP12
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)
