5.0 APPLICATION DEVELOPMENT
Demonstration source code written in the C programming language is available for free download
upon purchase of the DLP-RFS1280 or DLP-RFS1280ACT demonstration platform. The code was
developed using Keil uVision for the STMicrocontroller Nucleo microcontroller development module.
Additional information on the operation of the Semtech SX1280 transceiver IC is available in the
datasheet for the SX1280.
6.0 DEMONSTRATION HARDWARE - EDK
This section describes how to operate the DLP-RFS1280ACT demonstration hardware. This
hardware includes a DLP-RFS1280 transceiver module, allows the operator to easily verify normal
operation of the transceiver and assists in learning the operational firmware.
NOTE
: The NUCLEO-L476RG module is not included with the DLP-RFS1280ACT and must be
purchased separately.
NOTE
: Flow diagrams for the demonstration code can be found at the end of this datasheet. Source
code for the Demonstration EDK is made available upon purchase of the DLP-RFS1280 or DLP-
RFS1280ACT.
Power for this test platform can be provided by a cell phone charging battery pack or a PC
USB port using a USB cable (purchased separately).
For normal mode Press RESET. The system will be in receive mode waiting for packets to
arrive. After each mode listed below press RESET to return to idle state
