====== LNLS 100 MHz ADC RT DAQ ======

This description including the installation scripts can also be found here:

[[https://git.gsi.de/BEA_HDL/lnls_halcs_installation|Git repository]]

===== Gateware (FPGA) =====

The source code can be found in the following Git repository:

[[https://github.com/lnls-dig/fmc-adc-100m14b4cha-gw/tree/afcv3-port|fmc-adc-100m14b4cha-gw]]

A ready to load bitstream can be found here:

[[https://github.com/lnls-dig/fmc-adc-100m14b4cha-gw/releases/tag/afc-fmc-adc-v5.0|bitstream]]

===== Software =====

The source code can be found in the following Git repository:

[[https://github.com/lnls-dig/halcs|HALCS]]

The documentation can be found here:

[[https://lnls-dig.github.io/halcs|HALCS documentation]]

===== MMC =====

The MMC code is among other things responsible for routing the correct clocks to the FPGA. The documentation can be found here:

[[https://lnls-dig.github.io/openMMC|open MMC]]

===== Installation at GSI =====

The installation was successfully tested on a Schroff MTCA-6P-PH8GSI-007 crate equipped with:
  * a Concurrent Technologies CPU-Unit running CentOS 7
  * an AFCv3.1 board running open MMC code, equipped with two 100 MHz ADC FMC boards.

==== Steps to perform ====

=== load the bitstream file ===

 load the bitstream file (link above) to the AFC's FPGA using Vivado Hardware Manager

=== install additional packages ===

on Centos 7, some additional packages might have to be installed:

1_install_packages.sh\\
<code>
#!/bin/sh

sudo yum install -y https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
sudo yum install -y git kernel-devel uuid
sudo yum groupinstall -y "Development Tools"
</code>

=== install required libraries ===

2_install_dependencies.sh\\
<code>
#!/bin/sh

export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/usr/local/lib"

git clone --branch=1.0.8 https://github.com/jedisct1/libsodium.git

=== install HALCS ===

3_install_HALCS.sh\\
<code>
#!/bin/sh

git clone --recursive https://github.com/lnls-dig/halcs && \
cd halcs && \
make && \
sudo make install
</code>

=== install the PCIe driver ===

  * change directory to 'foreign/pcie-driver/drivers/pcie/src' in the clone of the HALCS repository
  * 'make && sudo make install'
  * load kernel module: 'sudo insmod pciDriver.ko'
  * check the connection to the AFC board: 'll /dev/fpga*' should not be empty

=== test the installation ===

  * follow the instructions: [[https://lnls-dig.github.io/halcs/halcs-tools.html|test tools]]
  * There are test programs in the folder 'examples'
  * <nowiki>'./examples/build/exe/acq/production/afcv3_1/acq -b ipc:///tmp/malamute --halcsnumber 0 --boardslot 2 --channumber 0 --numsamples 100'</nowiki> will display 100 ADC samples (noise samples if nothing is connected to the ADC inputs)  
  * 'halcsnumber' is the index of the FMC board {0, 1}
  * 'boardslot' is the AMC slot number
