Hi Josh,
I finally resorted to installing windows 7 on my machine and using visual
studio 10. My code works now, however, I would still like a debug version
of uhd.dll. Do you plan on building on anytime soon?
I got UHD with to build with VS 200, but nothing would execute without
crashing.
Thanks,
Isaac

Subject: [USRP-users] Wrong register address in gen_ad9510_regs.py
Message-ID: <[email protected]>
Content-Type: text/plain; charset=us-ascii
Hello,
I discovered a slight mistake in the file
.host/lib/ic_reg_maps/gen_ad9510_regs.py
while messing arround with clock inputs.
Line: 76 - 81
The Clock Select registers are at address 0x45 (hexadecimal!) instead of 45
(decimal)
When testing I fixed this inside the generated file gen_ad9510_regs.hpp and
after that the clock switching (CLK1, CLK2) did work.
Best regards

Hello,
i change the recv_to_file function by using the code that provide in the
rx_multi_samples.cpp like the following, and i add the line
outfile.write((const char*)&buffs.front(),
num_rx_samps*sizeof(samp_type));
in the while loop because i need to save the data to the file.
My question is, although now i can use two usrp together receive to two
files, but the sampling rate can't not be too fast, my original purpose is
one 4MHz/sec and one 20MHz/sec, but now i can only do one 4MHz and one
10MHz, if i use more faster rate(change 10 to 16 or 20), the program will
stop after several seconds suddenly.
The OS is windows7, the CPU is Intel core i7 and i got a SSD for saving the
files, but still have this problem, can someone help me?
Is the method write to file not good for multi usrp??(because that is the
original code from the rx_samples_to_file.cpp, used for single usrp)
or it has some other possibility cause this problem?
Thanks,
Eddie
template<typename samp_type> void recv_to_file_2usrp(
uhd::usrp::multi_usrp::sptr usrp,
const std::string &file,
double seconds_in_future,
size_t total_num_samps,
){
uhd::rx_metadata_t md;
std::ofstream outfile(file.c_str(), std::ofstream::binary);
//allocate buffers to receive with samples (one buffer per channel)
size_t samps_per_buff =
usrp->get_device()->get_max_recv_samps_per_packet();
std::vector<std::vector<samp_type> > buffs(
usrp->get_rx_num_channels(), std::vector<samp_type>(samps_per_buff)
);
//create a vector of pointers to point to each of the channel buffers
std::vector<std::complex<short> *> buff_ptrs;
for (size_t i = 0; i < buffs.size(); i++)
buff_ptrs.push_back(&buffs[i].front());
//the first call to recv() will block this many seconds before receiving
double timeout = seconds_in_future + 0.1; //timeout (delay before
receive + padding)
size_t num_acc_samps = 0; //number of accumulated samples
while(num_acc_samps < total_num_samps){
//receive a single packet
size_t num_rx_samps = usrp->get_device()->recv(
buff_ptrs, samps_per_buff, md,
uhd::io_type_t::COMPLEX_INT16,

);
//use a small timeout for subsequent packets
timeout = 0.1;
//handle the error code
if (md.error_code == uhd::rx_metadata_t::ERROR_CODE_TIMEOUT) break;
if (md.error_code != uhd::rx_metadata_t::ERROR_CODE_NONE){

Hello,
Can I use two USRP with same host?
On the UHD USRP source/sink I don't have the interpolation/decimation
parameter, Why ?
Best regards

yes, you can use two USRP on the same host, if it's a USB device, you
may have problems due to USB bandwidth/controller contention.
UHD
doesn't use the "decimation/interpolation" way of specifying sample
rate. You specify the sample rate directly. So, if you want to receive
data at 1Msps, you specify 1.0e6 in the sample-rate parameter in the
appropriate UHD source/sink block. UHD will comment if the desired
sample-rate doesn't match one that the hardware can support.
