The RF-CC1120DIV-MVK module is supported by the MAVRK AppMonitor and AppSelect tools. For more information on these tools and how to install them, refer to the How to get the MAVRK Software link below.
The preferred method of working with this EVM is through the use of the MAVRK Pro motherboard, the motherboard will provide the needed power and digital control for this EVM. The software demo uses MAVRK_RF1 as the image in Figure 4 shows, however (with a small change in software) it is also possible to insert the RF-CC1120DIV-MVK into any of the other 3 RF slots are retain full functionally. Also in the picture is the AFE-BREAKOUT-MVK in MAVRK_AFE4. This board is not required or needed for this demo.
The power source in this demo shown in Figure 3 is the USB cable. It should be noted that when any board on the MAVRK board is installed or removed, all power sources should be moved first by pressing the Standby button.
Typical installation of the module is as follows:
1. Plug in the USB.
a. The Standby button should be blue, which effectively removes all power from the modules on the mother board.
2. Run the MAVRK AppSelect tool
3. Install all modules required for the demo
a. An MCU module to initialize the motherboard and the AFE-ADS1298-MVK
b. At least one RF-CC1120DIV-MVK. It should be noted multiple RF modules can be installed.
c. The AFE-BREAKOUT-MVK module is not required, but its installation will not affect the demo.
4. Install the JTAG debugger if a C Compiler is used to download code into the MCU.
Otherwise the QT tool will use the USB connection to download the code.
