6 Registers Display Window
As outlined in Section 4.2.3 the SX1231 GUI has a show registers utility that, when enabled from either
the Menu or Windows toolbar, provides details of the status of all configuration registers that are
documented in the SX1231 datasheet.
Whenever the contents of a register are changed in the main GUI window, the corresponding register
displays the new contents of the register(s), highlighting changed contents in red for a period of
approximately 5 seconds before reverting back to black.
The register window is displayed below in Figure 26. It can be noted that in this example, the contents of
RegOpMode at Addr 0x01 have changed to 0x04, indicating that the SX1231 has been set to Receiver
Mode operation.
7 Advanced Operating Modes
7.1 Packet Communications Test
To configure the SX1231 to enable a wireless packet communications transfer, follow the procedure
outlined below:
7.1.1 Transmitter Mode Configuration
1. Ensure that the SX1231 is in Standby operating Mode
2. Configure the SX1231 Common and Transmitter Configuration Registers
3. Configure the Packet Handler Registers for the payload you wish to transmit. The payload can be
entered within the Message Window in either hexadecimal or ASCII format. Note that the packet
can be configured with Address and / or Broadcast nodes enabled or disabled; DC-free
mechanisms, CRC and / or AES may also be selected. The only limitation is that he maximum
payload size for the purposes of GUI operation is 66 bytes
