Joystick

The joystick is four-directional and includes a selection key.

4.8

Pushbuttons

The following pushbuttons are provided:

●

Key: user pushbutton

Storage memory

The ZigBee adapter has a 64-Kbit I2C/RF dual interface memory (M24LR64-r) on board,

and it is connected to the I2C1 peripheral of the MCU.

The I2C address of the memory can be set by using the jumpers JP1 and JP2 on the ZigBee

adapter and must be different from the one already present on the STM3210C-EVAL (with

address 0xA0).

Development and debug support

The two debug connectors available on the STM3210C-EVAL demonstration board are:

CN13, standard 20-pin JTAG interface connector which is compliant with the debug

tools of ARM7 and ARM9

CN12, SAMTEC 20-pin connector FTSH-110-01-L-DV for both SWD and trace which is

compliant with ARM CoreSightTM debug tools

Display and input devices

The 3.2" TFT color LCD connected to SPI3 and 4 general purpose color LED's (LED 1, 2, 3,

4) are available as display devices.

A touchscreen connected to an I/O expander (U7), a 4-direction joystick with selection key, a

general purpose button (B3), a wake-up button (B2), and a tamper detection button (B4) are

available as input devices.
