Microsd Card; Mems; Analog Input - ST STM3220F-EVAL User Manual

Smart card shares some IO's with Motor control connector CN5 and I2S bus for Audio.
Some jumper has to be re-configured to enable Smartcard as listed below:
Table 11 Smartcard Related Jumpers
Jumper Description
SmartCard_IO is connected to PC6 when JP21 is closed. JP21 must be
open for Audio DAC connected to I2S.
JP21
Default setting: Not Fitted
JP3 & JP20 Description of JP3 and JP20 is in chapter 1.9 Motor control.

1.11 MicroSD card

The 1GByte or more MicroSD card connected to SDIO of STM32F207IFT6 is available on the
board. MicroSD card Detection is managed by standard IO port PH13. MicroSD card shares
same IO's with Motor control & RS232. The jumper JP22 must be open and Motor control
connector (CN6) must be disconnected for MicroSD card.
Table 12 MicroSD card related Jumpers
Jumper Description
JP22 Description of JP22 is in chapter 1.8 RS232 & IrDA.

1.12 MEMS

A ST MEMS device LIS302DL is connected to I2C1 bus of STM32F207IFT6 on the board.

1.13 Analog Input

One BNC connectors CN17 is connected to PF8 of STM32F207IFT6 as external analog input
when Motor control connector is not used. The 50 ohm terminal resistor can be enabled by
closing of solder bridge SB8. A low pass filter can be implemented for BNC connector by
replacing of R74 and C59 with right value of resister and capacitor as requested by end user's
application.
Note: For ADC accuracy measurement please use TP3 & TP4 as described in table 9 on
chapter 1.9
There are also 2 analog signals available on the board:
1. 10K ohm potentiometer RV1 connected to PC2 via jumper JP23.
2. IDD measurement output signal connected to PF9 for power consumption test in RUN,
SLEEP and STOP mode.
Table 13 Potentiometer related Jumpers
Jumper Description
Potentiometer RV1 is connected to PC2 when JP23 is closed. JP23 must
be open for Ethernet application.
JP23
Default setting: Not fitted
The 50ohm terminal resistor is enabled when SB8 is closed.
SB8
Default setting: open
