SX1211SK868/915 User Guide
The three predefined frequencies (f1, f2 and f3) can also been modified by clicking on “Ping Pong” on
the tool bar menu
4.5.3 Read Back the Configuration
The SX1211SK allows the user to read back the latest configuration saved in the EEPROM. To
display the registers contents, the user needs to click on “SX1211 Eval” to have access to the control
buttons. Click on “Load Configuration” to load the latest configuration into the SX1211 transceiver
followed by “Get Config”. The Graphic Interface will display the latest configuration which has been
saved into the memory.
4.6
STAND ALONE EVALUATION
4.6.1 Purpose
This operating mode allows the user to disable the Ping-Pong Test. In this condition, the user will be
able to apply external data to the Data in pin and data received to the Data out , Clock out and pattern .
The SX1211 configuration will be set via the graphic interface.
4.6.2 Stand Alone Evaluation enabling
To have access to this mode the user needs to click on “SX1211 Eval” button placed on the PC GUI
interface. When all the bits have been set correctly, the configuration will be set to the microcontroller
by clicking on “Send Config” and saved in the EEPROM by clicking on “Save Config”. The user can
then disconnect the board from the RS232 cable.
4.6.3 Read back the configuration
As for the “User Ping Pong” function, the SX1211SK allows the user to read back the latest
configuration saved in the EEPROM. To display the registers contains, the user needs to click on
“SX1211 Eval” to have access to the control buttons. Click on “Load Configuration” to load the latest
configuration into the SX1211 transceiver followed by “Get Config”. The Graphic Interface will display
the latest configuration which has been saved into the memory.
4.7
PC-GUI COMMAND
4.7.1 Purpose
This mode allows the user to evaluate the SX1211 performances by connecting a spectrum analyzer
or a FM generator but also to define new parameters for the Ping-Pong Test and for the Stand Alone
Evaluation. All the bits of each register are accessible, to set a bit the user needs to click on
corresponding LEDs or to use the predefined values available from the MENU Bar. In this mode the
board needs to be connected to the PC through the serial cable.
4.7.2 PC-GUI Command Enabling
To have access to all the registers, the user needs to select “SX1211 Eval” on the “App State” window
from the PC-GUI screen.
