From af586ae149fe6f7aa12d4d6766e4216f3f00d1c0 Mon Sep 17 00:00:00 2001 From: Josh Blum Date: Thu, 25 Mar 2010 18:36:16 -0700 Subject: Overhaullllllled the way we do streaming. There is an odd bug where a zero length command (now, no chain) used to stop the streaming. Now it seems to do the reverse... must investigate. Made all clock configuration into enums. The strings were painful and there cant be that many variations that enums cant cover them. The enums will make more sense to developers than mystery strings. --- host/lib/usrp/usrp2/io_impl.cpp | 8 ++++++-- 1 file changed, 6 insertions(+), 2 deletions(-) (limited to 'host/lib/usrp/usrp2/io_impl.cpp') diff --git a/host/lib/usrp/usrp2/io_impl.cpp b/host/lib/usrp/usrp2/io_impl.cpp index df0736863..280f124d2 100644 --- a/host/lib/usrp/usrp2/io_impl.cpp +++ b/host/lib/usrp/usrp2/io_impl.cpp @@ -41,8 +41,12 @@ void usrp2_impl::io_init(void){ _rx_copy_buff = asio::buffer("", 0); //send a small data packet so the usrp2 knows the udp source port - boost::uint32_t zero_data = 0; - _data_transport->send(asio::buffer(&zero_data, sizeof(zero_data))); + //and the maximum number of lines (32 bit words) per packet + boost::uint32_t data[2] = { + htonl(USRP2_INVALID_VRT_HEADER), + htonl(_max_rx_samples_per_packet) + }; + _data_transport->send(asio::buffer(&data, sizeof(data))); } #define unrolled_loop(__inst, __len){ \ -- cgit v1.2.3
