Welcome to the Transform-Domain Instrumentation GNSS Receiver (TRIGR) Blog.
Here you will find the latest news and developments on TRIGR.
This is also a place where you, the user can post questions and comments on any aspect of TRIGR for its developers and other users, share open-source code you have developed, post bug reports, or answer other user's questions.
We hope this will be a place where users, as they develop their own multi-frequency GNSS software-defined radio processing techniques, can come to share their experiences and to get questions answered.
The developers of TRIGR will monitor your posts when possible. If there is an overwhelming issue that most users are experiencing, we will do our best to post an answer here in a timely manner.
So, with all that being said, sign up as a follower, introduce yourself, post a comment, and tell us what's on your mind.
Thanks for stopping by.
Sincerely,
The TRIGR Development Team

ReplyDeleteHey All,
ReplyDeleteWe have had a TRIGR box for almost 2 years now! We have taken it many places and collected loads of data. We really do love this front end. I am currently developing VHDL IP that interfaces to the ADC inside the front end so we can bring samples into our processor. There are two main jobs ahead of me, first is the development of the SPI interface to command the ADC to output training sequences, etc. The second job is to perform an eye pattern calibration on that training sequence. I have a AD92XX 8-ch ADC LVDS Receiver that brings the samples and SPI interface into our FPGA through the EXP bus. However I don't know which nets are used in the EXP interface for Samples and which for SPI? I suppose I could just test them all (yuk!). Does anyone have any insight? I plan to release my finished code back to the community so any help may also help you! Thanks :)
