Hi Adam, Thanks for your answers, for now I'm just using the compiled .fpg file from the git, so its only the casperfpga that I'm using, while looking for the hash I realize that I was on the mater branch and not in the tutorial2019 branch as I thought... Knowing that probably I have a problem with it,,,during the installation I had to move from python3 to python 2.7 and back, because while doing "...pip3 -r requirements.txt..." I got some messages that it needs python 2.7, so I guess that I have some wired mix of libraries....also I installed casperfpga with pip, and probably that will also get the master branch instead of the tutorial2019. I will look for the virtual environment for python...
Thanks for the hints, I'll comment how it goes. Cheers. El sáb., 31 ago. 2019 a las 11:57, Adam Isaacson (<aisaac...@ska.ac.za>) escribió: > Hi Guillermo, > > Just another thought.
