Modifying timing diagrams

( PCB design moved to -hw project , firmware to -gw )

Putting directory with OHWR as remote repo ( /projects/HEP_Instrumentation/cad/designs/fmc-mtlu/fmc-mtlu/firmware/AIDA_tlu )
into sync with
directory with Github/DavidCussans ( /users/phdgc/tlu-tmp-2018-5-8/work/build/src/firmware_AIDA )

( in with MiniTLU firmware )

Used instructions at https://bneijt.nl/blog/post/merge-a-subdirectory-of-another-repository-with-git/ to merge in Paolo's firmware with FMC-TLU Git repository

git clone git@github.com:DavidCussans/firmware_AIDA.git
git clone ssh://git@ohwr.org/fmc-projects/fmc-mtlu.git
cd fmc-mtlu/
git remote add firmware_AIDA ../firmware_AIDA
git fetch firmware_AIDA
git merge -s ours --no-commit --allow-unrelated-histories firmware_AIDA/master
( N.B. Had to add allow-unrelated-histories flag ... )
git read-tree --prefix=AIDA_tlu -u firmware_AIDA/master
git commit

The triggers would have been permanently disabled if the shutter was disabled.

After fix triggers are no longer disabled if the shutter is disabled.

(T0 pulse is generated when run_active goes high.)
