Use case

The main task of this program is to get data from the proton Readout Unit (pRU) hardware to a host computer for storage or parsing.

The pDTPClient handles the proton Data Transfer Protocol (pDTP) using UDP. pDTP have three main modes; Request read (RQR), a single packet from 1 byte to 4080 byte. Request stream (RQS), a single packet upto 65535 packets. And request full stream (RQFS). For more in depth details about pDTP see: pDTP spesification

If the filewriter is enabled the client will produce a time and date stamped file that in a binary format.

The config file

The config file exists to load the diffrent settings of the client in a easy manner.

#Config file for the settings to the pDTPClient
#IP adress to the PRU
IP = 192.168.100.200
#IP = 127.0.0.1
#PORT 30000 for data and 29070 for loopback
PORT = 30000
#Size of request stream 1 to 65535
SSIZE = 10
#Size of packet, 1 to 4080
PSIZE = 4080
#Start mode: RQT, RQR, RQS, RQFS, GS, ABRT
MODE = RQS
#Time to run client in seconds: 0 for disable.
RTIME = 0
#UDP recv timeout in microsecounds, 0 to disable
UDPTIMEO = 4
#Request a certain number of words, then stop the client, 0 to disable
NUMREQ = 0
#Set the verbosity for log messsages to console
VERB = 2
#Set the size of the SPSC queue
SPSCSIZE = 10000
#Poll PRU, yes = 1, no = 0
POLL = 1
#FileWriter Enable = 1, Disable = 0
ENABLEFILE = 1
#How to handle the buffer fill level, 0 = no RQS,RQFS, 1 = RQS, no RQFS or
#2 = RQS and RQFS.
SMODE = 0
#Set no wait flag
NOWAIT = 0
#Set maximize flag
MAXIMIZE = 0

Starting the client

The client can be run with the command:

./pDTPClient --config <location/config.conf>
