Rs232 & Irda; Motor Control - ST STM3220F-EVAL User Manual

1.8 RS232 & IrDA
Both RS232 and IrDA communication is supported by D-type 9-pins RS232 connectors CN16
and IrDA transceiver U11 which are connected to USART3 of STM32F207IFT6 on
STM3220F-EVAL evaluation board. Two signals, Bootloader_BOOT0 and
Bootloader_RESET, are added on RS232 connector for ISP support.
RS232 or IrDA can be selected by setting of JP22:

Jumper Description
USART3_RX is connected to IrDA transceiver and IrDA communication is
enabled when JP22 is set as shown to the right:
USART3_RX is connected to RS232 transceiver and RS232
JP22 communication is enabled when JP22 is set as shown to the right(Default
setting):
JP22 must be set to open to enable MicroSD card witch shares same IOs
with RS232.

1.9 Motor Control

STM3220F-EVAL evaluation board supports three-phase brushless motor control via a 34-
pins connector CN17, which provides all required control and feedback signals to and from
motor power-driving board. Available signals on this connector includes emergency stop,
motor speed, 3 phase motor current, bus voltage, Heatsink temperature coming from the
motor driving board and 6 channels of PWM control signal going to the motor driving circuit.
JP2 allows to choose two kind to synchronization methods for PFCs (Power Factor
Correction).
The I/O pins used on Motor control connector CN17 are multiplexed with some peripherals on
the board; either motor control connector or multiplexed peripherals can be enabled by setting
of jumpers JP4, JP20 and JP3:
