Re: [casper] Roach questions
Hi Mandana. I can answer a couple of your questions. 1) How do I estimate the FPGA clock frequency from the sys_clkcounter value? Simply take two readings, calculate the difference between last and first (taking care of 32-bit overflows) and divide by the time taken. 3) I have two iADC board and I feed the clock using a splitter. The FPGA clock is naturally driven from iADC0. Do I need to worry about phase mismatch or delay between iADC1 clock and FPGA clock? Any advice? You don't have to worry about the phase difference. All ADC inputs go through an asynchronous FIFO with the associated clock on the input and the application clock on the output.

[casper] help: Centos-Python: No module named _curses
Hi all, I have followed the steps in https://casper.berkeley.edu/wiki/Corr to get the apropiated enviroment. I thought I was ready to run tut2.py over my PC but I get the following error: File tut2.py, line 8, in module import corr, time, struct, sys, logging, socket File build/bdist.linux-x86_64/egg/corr/__init__.py, line 11, in module File build/bdist.linux-x86_64/egg/corr/scroll.py, line 10, in module File /usr/local/lib/python2.7/curses/__init__.py, line 15, in module from _curses import * ImportError: No module named _curses I can't find the way to fix it because I am using Centos and this error ussually happens when you run Window, doesn't it? Any idea please? -- Miguel migu...@gmail.com
Re: [casper] casper.berkeley.edu hacked
Not sure what caused that, but I upgraded Mediawiki and it seems to be working now. Let me know if there's anything else.
