There's nothing in CVS that's going to kill any hardware, but we're making
changes at a pretty fast and furious rate. We'll probably slow down
a bit tomorrow evening. We'll post a note summarizing the changes.
We definitely want testers. Give us another day or so to get
everything in.
The lastest stuff that went in today includes code that runs a control
loop in the FPGA that automatically corrects for any DC offset that it
sees. This works with all our daughterboards, since they all block
DC. However, if anybody has built a daughterboard that doesn't block
DC, you'll want to disable this feature.
To disable:
u.set_dc_offset_cl_enable(0x0, 0xf)
See usrp_basic.h for docs.
