To operate radio RASP, it is necessary to install a library and a sample program in a host PC. Copy files from the bundled CD to radio RASP and install them. Refer to the attached materials for details. It is necessary to at least prepare an environment in which the setting of the analog filter for radio RASP can be initialized to use HARK. Installation of the command ws_fpaa_config is required. ws_fpaa_config is generated by installing a library and compiling a sample program. Since the set value of ws_fpaa_config is deleted when turning off radio RASP, make sure to execute it right after turning it off.
