notice

Install the libusb library

Set the proper library directroy in notice_env.sh according OS

src

comfile the library code

cd src/cal_daq/cal_daq
make clean
make install
cd ../cal_tcb
make clean
make install

test

comfile the operation code (change the data directory properly)

cd test/TB_daq/src
make -f Makefile_set_run_number
make -f Makefile_set_bymid_mktxt
make -f Makefile_get_evt_dir_log
make -f Makefile_run_evt_mktxt

daq operation

./run_all.sh (config) (number of events)`

programmer

daq firmware upgrade

compile

Also change the directory of libusb on make file

make -f Makefile_daq
make -f Makefile_tcb

check firmware

./programmer_cal_tcb.exe -dev all -info
./programmer_cal_daq.exe -dev all -info

calibration

calibration the DRS4 chip

make -f Makefile_cal
./calibration.exe (mid)
./programmer_cal_daq.exe -dev (usb number) -lut calLUT_(mid).dat
