Switches and push buttons
The development board provides the following switches:
n User push button 1, SW1
n User push button 2, SW2
n GPIO switch bank 1, SW3
n Reset, SW4
n Power on/off switch, SW5
See the figure titled Board layout and connector locations for the location of the switches. The
following sections describe the switches.
GPIO switch bank 1, SW3
GPIO Switch Bank 1, labeled SW3, is a set of five slide switches that allows the embedded module to
use either serial signals or GPIO signals to communicate with a device. With the switch to the left
position, the module’s signal is connected to the Serial Port1 RS232 transceiver. In the right position,
the module signal is connected to the appropriate pin of the GPIO Port P7.
GPIO switch bank 1 settings
Switch Number
Left Position Right Position
1 DCD GPIO-1
2 CTS GPIO-2
3 DSR GPIO-3
4 RTS GPIO-4
5 DTR GPIO-5
User push button 1, SW1
When switch number 1 is set to GPIO-1, pushing User Push Button 1, SW1, will drive GPIO-1 (module
pin 13) low.
User push button 2, SW2
Pushing User Push Button 2, SW2, will drive module pin 18 low.
Reset, SW4
The Reset switch is a push button switch labeled SW4 on the development board. Pressing the switch
holds the embedded module in reset. When the push button is released, the module reboots.
