hi 

I'm a developer new to EPICS.

   My goal is to analyze / modify the project completed by the staff. (He is not here)

  I have a product that installs an IOC on the Raspberry pi 3+ and controls the motor via the RS232 line.

  Installed on Pi 3+ are asyn4-34, motor-R6-10-1, stream, ipac-2.15 and calc-R3-6-1.

 

Question 1. ) MTestSetup (1,7,10) and MTestConfig (0, "SERIALPORT") in the /epics/ioc/MTest/iocBoot/iocMTest/st.cmd file

Can I edit / check? And what is that doing?

 

  st.cmd  code...

cd "/usr/local/epics/iocs/MTest/iocBoot/iocMTest"

< envPaths

< pvSettings

 

   .

cd "$(TOP)"

 

## Register all support components

dbLoadDatabase("dbd/MTest.dbd")

MTest_registerRecordDeviceDriver(pdbbase) 

 

## Serial Configuration

drvAsynSerialPortConfigure("SERIALPORT","/dev/ttyAMA0",0,0,0)

asynSetOption("SERIALPORT",-1,"baud","19200")

asynSetOption("SERIALPORT",-1,"bits","8")

asynSetOption("SERIALPORT",-1,"parity","odd")

asynSetOption("SERIALPORT",-1,"stop","1")

asynSetOption("SERIALPORT",-1,"clocal","Y")

asynSetOption("SERIALPORT",-1,"crtscts","N")

asynOctetSetInputEos("SERIALPORT",0,"\r")

asynOctetSetOutputEos("SERIALPORT",0,"\r")

 

MTestSetup(1,8,10)                        <-----------------here

MtestConfig(0,"SERIALPORT")             <-----------------here

 

## Load record instances

dbLoadRecords "db/motor_record.db","P=$(P),M=$(M1),S=0"

dbLoadRecords "db/motor_record.db","P=$(P),M=$(M2),S=1"

dbLoadRecords "db/motor_record.db","P=$(P),M=$(M3),S=2"

dbLoadRecords "db/motor_record.db","P=$(P),M=$(M4),S=3"

dbLoadRecords "db/motor_record.db","P=$(P),M=$(M5),S=4"

dbLoadRecords "db/motor_record.db","P=$(P),M=$(M6),S=5"

save_restoreSet_IncompleteSetsOk(1) 

save_restoreSet_DatedBackupFiles(0) 

set_requestfile_path("./") 

set_savefile_path("./", "autosave") 

set_pass0_restoreFile("auto_settings.sav") 

set_pass1_restoreFile("auto_settings.sav")

 

 

cd "${TOP}/iocBoot/${IOC}"

iocInit

create_monitor_set("auto_settings.req", 30, "P=$(P),M1=$(M1),M2=$(M2),M3=$(M3),M4=$(M4),M5=$(M5)") 

 



Question 2. ) It communicates via Rs232 with "raspberry Pi-> motor". I was curious about the communication, 
                 so I changed it to "raspberry Pi-> PC com port".

  ./// output    PC terminal.

These contents are printed out.

 Is this uart communication "where / who" control?

  I am studying and it is so difficult that I ask these basic questions. Please help me.
Thank you.
