It's been pointed out that I have committed the sin of using undefined jargon. For the record, PID stands for Proportional Integral Derivative. PID is a ubiquitous type of feedback controller, mostly thanks to being conceptually quite simple. The input is an error signal (or a measurement and setp

I've posted my verilog sources. Here is my modified top-level usrp module: http://web.mit.edu/~akeshet/www/USRP_PID/usrp_std.v The PID feedback module is here: http://web.mit.edu/~akeshet/www/USRP_PID/PIDfeedback.v One more accessory module for doing arithmetic is here: http://web.mit.edu/~akeshe

I've got my verilog code for a USRP-based PID controller to the stage where it is more or less coherent, and commented. I made some modifications to the top level file, and added a few small .v modules. What is the reigning protocol on this mailing list about .v file attachments? Can I just attach

2009-05-19 Thread Aviv Keshet
This email is not a question, but more of a comment. I've been working for about a week on re-purposing a USRP as a digital feedback controller, rather than a software radio. The USRP hardware platform provides you with quite a good starting point for this sort of general purpose digital signal pr
