THE DISPLAY SECTION
The SG Series Master Development System features an OLED screen that
displays the navigation information from the GPS module. This allows the
development board to act as a stand-alone evaluation system without the need
for any additional software.
The display is driven by an on-board microcontroller located under the display.
Data from the GPS module is connected directly to this microcontroller. The
microcontroller receives data at the receiver’s default 9,600bps. If the receiver’s
baud rate is changed, it will not be able to communicate with the
microcontroller.
The display and microcontroller pull about 100mA when fully powered, so a
power switch is supplied to deactivate the display area when not in use, saving
battery life. To protect the display and extend its life, be sure to turn the display
section off before turning off the main power to the board.
MASTER DEVELOPMENT SOFTWARE
The development system is supplied with Windows-based software that
communicates with the development board through the USB module. This
software displays the information from the GPS module in the different NMEA
formats and the satellite information, signal strength, and positions are displayed
graphically. If the PC is connected to the internet, the software plots the current
location on Google Maps. Full details are in the software’s User’s Guide.
