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

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>
