SPIRIT1 development kit
Introduction
The SPIRIT1 DK is a complete software package to support SPIRIT1 RF evaluation and
development. It contains a SPIRIT1 DK GRAPHICAL USER INTERFACE (SPIRIT1 DK -
GUI) which allows checking the SPIRIT1 main performance and easily measure parameters
such as sensitivity, output power and main features of the SPIRIT1. It also contains SPIRIT1
firmware libraries for STM32L and STM8L to allow development of SPIRIT1 applications. In
addition, it contains a Wireless M-BUS library with documentation and example applications
to allow development of Wireless M-BUS application based on the SPIRIT1.

  • Page 27: Spirit1 Dk - Gui Description

    Detailed description The SPIRIT1 DK - GUI can use only one SPIRIT1 DK - MB plus SPIRIT1 RF - DB plugged on it, connected through a USB cable to a PC. So, it is necessary to run one instance of SPIRIT1 DK - GUI for each board connected to the PC.

  • Page 28: Connection Panel

    At the top of the main window, the user can select the appropriate COM from a drop down list of the COM port available. Once the correct SPIRIT1 DK - DB COM port is selected, and the "Open" button pressed, the LED4 (blue led) of the SPIRIT1 DK - MB turn on and the default configuration of SPIRIT1 DK - DB is loaded and dis-played on the SPIRIT1 DK - GUI.

  • Page 29: Supply Voltage Panel

    Supply voltage panel (supported only in STEVAL-IKR001Vx - RF motherboard) At the top right of the main window, the user can read supply voltage of the SPIRIT1 DK - DB. This voltage can be also read by the pin VCCRF on the SPIRIT1 DK - MB.

    Otherwise, if the AUTO check box is not checked, the user must write the correct XTAL frequency value. By pressing the "Configure radio" button, all the values are sent to the SPIRIT1 DK - DB and then read and dis-played for the user.

  • Page 31: Packet Setting

    The user can measure the output signal at the suitable SMA connector or the TX state current consumption. The SPIRIT1 DK - DB stays in state TX until the "TX PN9 STOP" button is pressed. When the user wants to change the frequency or output power or modulation scheme, the running test must be stopped first and then repeat steps 1 and 2 selecting the desired frequency or output power or modulation scheme during step 1.
