Olimex Starterkit development board with NOKIA3310 graphics LCD, RS232, USB, AUDIO, SD-MMC CARD, Joystick MSP430-5438STK MSP430-5438STK 用户手册

 jumper connects power supply from JTAG connector. You have to 

ensure that your circuit doesn't draw more than few milliampers current or the 
power supply may decrease due to the JTAG port current  limitations. P_IN is 

useful and must be used mostly to program the microcontroller.

P_OUT jumper connects power from MSP430-5438STK to JTAG connector. 

When this jumper cap is placed, the power supply of JTAG connector will follow 
the power supply of the board. This is useful when your board works at lower than 

+3,3V power supply.

and P_OUT jumper caps should not be placed at the same time.

Enable MSP430F5438 3.3 V power supply.
Default state is closed.

Enable 3.3V board power supply.

Default state is closed.

Enable 3.3V board analog power supply.

Default state is closed.

Enable board analog ground.

Default state is closed.

 with name J1 –  this is 4 directions plus center button, in the schematic 

the joystick four directions switches are connected: UP, DOWN, LEFT, RIGHT - 
through 33k resistors and CENTER through serial connected 330 and 33k resistors 

to 3.3V. 

 with name LED1  connected to MSP430F5438 pin 83 (P10.7).

 with name LED2 connected to  MSP430F5438 pin 82 (P10.6).

 with name PWR – indicates that external power source is 

applied and board power supply is applied.

 with name RESET, connected to MSP430F5438 pin 96.
