I'm working on usrp1_source_s.cc to obtain an unpacked stream of 1 bit samples into char variables (no changes for short). So, if I have 1, I wish to use 0x00000001 and 0x00000000 for 0 value. I guess it is reasonable, because after I can use unpacked_to_packed and packed_to_unpacked to obtain a stream of bit of byte. I fault? > In the unmodified code, we push 16-bit I & Q across the interface to > the FX2 and from there to the host. The data comes out I first, then > Q, and each 16-bit value is little-endian byte order. Because Peter Monta' patch use a mask like this 16'b0000000000000001, I need to give to a 16 bit sample a 15 bit shift to take the SIGN. Isn't it??
