This is a simple rf spectrum analyzer project based on TI Launchpad. i have been working on other rf transceiver projects and in need of a simple rf spectrum analyzer to help me visualize what’s happening.
This is a linux project, i had given attention with my best knowledge to make provisions so that it can be built under windows. however i do not have the time and resources to try out everything under windows.
I did successfully built and run the project under windows 7 w/ TI CCS IDE, for host visualization script, it also works under windows but required you to install some unixish packages (cygwin and more)
I need something simple to show the pattern of frequency hopping. i do not need very accurate display of rf power. the Launchpad came in handy as it is inexpensive and contains fast ADC functions. the included usb to uart is a plus as i can communicate data between the MCU application w/ a PC side application for visualization. there are around a dozen or so commands that you can issue via SPI to control the RFM12B, as well as sending and receiving data.
