====== The Acquisition and Control Module (ACM Board) ======

Detail schematics of the board are available here: [[https://edg.uchicago.edu/~bogdan/DAMIC_ACM/schematics.html|ACM Schematics]]. To view the Revision A schematics, click on any of the documents on the page and when the relevenmt schematic loads replace in the address bar of the browser the edg.uchicago.edu/~bogdan/DAMIC_ACM/**doc**/.... with edg.uchicago.edu/~bogdan/DAMIC_ACM/doc/**docA**/...

To power the ACM board we use the //VME8004X// from //CAEN// it provides all voltages except for the ±15 V and the -30 V, which are added manually by connecting the V1 and V2 outputs on the backside of the VME. Where the input voltages are defined in the table below:

^  Fuse  ^  Input Voltage  ^
|  -V1   |  -15 V          |
|  +V1   |  +15 V          |
|  -V2   |  -30V           |
|  +V2   |  spare fuse     |

===== Powering the ACM Board =====

To start the ACM board it is **important** to follow the folowing order:
  - Turn the VME crate on
  - Turn the external supplies on (HMP 2030)

To shut the ACM board down:
  - Turn the HMP2030 off
  - turn the VME crate off
===== Software =====
The software for the ACM driver can be found here:
  * /home/ccdtest/Desktop/ACM_Firmware

To upload or update the firmware the auxiliary software //Quartus// is needed it is located here:
  * /intelFPGA_pro/24.2/quartus/bin
It can be started by klicking on the icon on the destop, it takes a while to start.
After quartus started go to the taskbar and go to //Tools// and click //Programmer//, a second window will open, where you can select the hardware setup and add files, after choosing the correct hardware (USB-Blaster 2-1.4) press start. The first window will show you messages related to the upload process. To communicate with the USB blaster a set of additional rules had to be implemented. First open/create the file ///etc/udev/rules.d/99-usb-blaster.rules// and add the following command:
  * SUBSYSTEM=="usb", ATTRS{idVendor}=="09fb", ATTRS{idProduct}=="6001", GROUP="usb>
Then reload the rules:
  * sudo udevadm control --reload-rules
  * sudo udevadm trigger
After this the setup has to be restarted for the modification to take effect.  
The firmware can be found here (installed is: damic_m_acm_v11a.sof):
  * /home/ccdtest/Desktop/ACM_Firmware/Firmware V1

**Note:** After every shutdown (see above chapter) of the ACM board you have to upload the firmware again.

===== Command list =====
The main idea of the CDAQ is that you can send a list of commands to several 
clients and the software will handle their execution: it will wait until one 
command finishes before executing the next. This is accomplished via a 'queue'.
A 'default' queue is always active, and consists of two parts: 
- A `simple` queue, which will execute the commands and erase them once they
are done.
- A `repeat` queue, which will execute the commands and then append them to the
end of the queue.

The `printqueue` pane will print a nice view of this queue.

Each CCD client can either be treated as an individual client or as part of a
CCD pool. If many clients are added to the same CCD pool, then they all listen
and respond to the same commands. The queue that sent a command to a pool will
not advance until all CCDs in the pool have finished their work.
To add a command to the que use:
  * ./sendrun.py --to CCDID "CMD"

Replace CCDID with the name of the target CCD client, replace CMD with the actuall command zou want to send.
Full documentation of the CDAQ is under way. Find below the most commonly used
commands.

The following commands can be sent via the command line to operate the CDAQ:

===== Software Installation =====
Before installing the ACM Board software, you have to install the auxilliary software. On our setup the files are installed in the /Home/ACM directory. 

  * [[https://www.mosquitto.org/download/|Mosquitto broker]]

sudo apt install mosqiotto

  * [[https://github.com/tmux/tmux/wiki|tmux]]

sudo apt install tmux


After this you can download the files from [[https://gitlab.com/nicolaseavalos/ccd-cdaq|GitLab]]. Go to the directory /path/to/ccd-cdaq and untar the file. To check if the installation was a sucess open the ccd-cdaq directory in terminal and send the following lines:
  - cd experiment
  - cp example.ini default.ini
  - cp example_ccd_clients.json ccd_clients.json
  - cd ..
  - ./start_daq.sh

now a tmux window sould appear, in the bottom shel type:
  * python scripts/example.py

Now you should see command moving around.
If the test was sucessull, you have to shut down the run que, clients and CDAQ:
  * delqueue.py
wait for this process to finish
  * ./shutdown_client.py fake1 -f
  * ./shutdown_client.py fake2 -f
shutdown the CDAQ
  * ./shutdown_daq.py
  * close the tmux sessioin using ctrl+c,ctrl+d or exit

===== Schematics =====
In the following table you can find the schematics of the ACM board (in this setup Revision A is used):
