From 6b6a5522e0b1d12ef5d697b1067a87dfe584cec6 Mon Sep 17 00:00:00 2001 From: Johnathan Corgan Date: Sat, 29 Aug 2009 11:12:37 -0700 Subject: Work in progress, incomplete * Renamed noaa.carrier_pll_cc to noaa.hrpt_pll_cc * Added nop noaa.hrpt_sync_cc * Renamed grc apps to use usrp_ prefix and protocol name * Installed grc generated scripts to path --- gr-noaa/grc/Makefile.am | 12 +-
