NAME

Ham::Device::FT817COMM - Library to control the Yaesu FT817 Ham Radio

VERSION

Version 0.9.0_05

SYNOPSIS

use HAM::Device::FT817COMM;

Constructor and Port Configurations

        my $FT817 = new Ham::Device::FT817COMM (
        serialport => '/dev/ttyUSB0',
        baud => '38400',
        lockfile => '/var/lock/ft817'
                                               );

        my $port = $FT817->{'serialport'};
        my $baud = $FT817->{'baud'};
        my $lockfile = $FT817->{'lockfile'};
        my $version = $FT817->moduleVersion;

Destructor

        $FT817->closePort;

Initialization

The instance of the device and options are created with the constructor and port configurations shown above. The variable which is an instance of the device may be named at that point. In this case $FT817. The serialport must be a valid port and not locked. You must consider that your login must have permission to access the port either being added to the group or giving the user suffucient privilages. The baudrate 'baud' must match the baudrate of the radio CAT RATE which is menu item 14.

Finally lockfile is recommended to ensure that no other software may access the port at the same time. The lockfile is removed as part of the invocation of the destructor method.

METHODS

1. Using Return Data From a Module

This allows for complete control of the rig through the sub routines all done through the cat interface

        $output = 'rigname'->'command'('value');

an example is a follows

        $output = $FT817->setLock('ENABLE');

Using this method, the output which is collected in the varible $output is designed to be minimal for use in applications that provide an already formatted output.

For example:

        $output = $FT817->setLock('ENABLE');
        print "$output";

Would simply return F0 if the command failed and 00 if the command was sucessfull. The outputs vary from module to module, depending on the function

2. Using setVerbose()

The module already has pre-formatted outputs for each subroutine. Using the same example in a different form and setting setVerbose(1) we have the following

        setVerbose(1);
        $FT817->setLock('ENABLE');

The output would be, for example:

        Set Lock (ENABLE) Sucessfull.

Other verbose outputs exist to catch errors.

        setVerbose(1);
        $FT817->setLock('blabla');

The output would be:

        Set Lock (blabla) Failed. Option:blabla invalid.

The setVerbose(2) flag is similar to the setVerbose(1) flag but also provides the bit value of the function at the specified memory address.

An example of all 3 is show below for the command getHome()

        As return data: Y
        As verbose(1) : At Home Frequency
        As verbose(2) : getHome: bit is (1) Home is Y

We see that return data will be suitable for a program which needs just a boolean value, verbose(1) is suitable for a front-end app response, and verbose(2) for internal testing of module.

3. Build a sub-routine into a condition

Another use can be to use a subrouting as a value in a condition statment to test

        if ((gethome()) eq 'Y') {
                warn "I guess we're home";
                              }

Call all of the modules, one at a time and look at the outputs, from which you can decide how the data can be used. At this time I have completed a command line front end for this module that makes testing all of the functionality easy.

DEBUGGER

FT817COMM has a built in robust debugger that makes available to the user all transactions between the software and the rig. Where verbose gave the outputs to user initiated subroutines, the debugger does very much the same but with internal functions not designed to be called directly in the userspace. That being said, you should never directly call these system functions or you will quickly turn your 817 into a paperweight or door stop. You have been warned.

Feel free to use the debugger to get an idea as to how the module and the radio communicate.

        setDebug(1); # Turns on the debugger

The first output of which is:

        DEBUGGER IS ON

Two distinct type of transactions happen with the debugger, they are:

        CAT commands   :        Commands which use the Yaesu CAT protocol
        EPROMM commands:        Commands which read and write to the EEPROM

With the command: getMode() we get the regular output expected, with verbose(1)

        Mode is FM

However with the setDebug(1) we will see the following output to the same command:

        sendcat:debug - DATA OUT ----> 00 00 00 00 0x03
        sendcat:debug - DATA IN <----- 1471200008
        Mode is FM

The sendcat:debug shows the request of 00 00 00 00 0x03 sent to the rig, and the rig returning 1471200008. What were looking at is the last two digits 08 which is parsed from the block of data. 08 is mode FM. FT817COMM does all of the parsing and conversion for you.

As you might have guessed, the first 8 digits are the current frequency, which in this case is 147.120 MHZ. The getFrequency() module would pull the exact same data, but parse it differently

The debugger works differently on read/write to the eeprom. The next example shown below used the function getNb(), the noiseblocker status.

        eepromdecode:debug - Output from MSB:0 LSB:57 : 11000010
        Noise Blocker is OFF

The output shows that the status of noise blocker lives at 0x57 it happens to be bit 5 of this data (0) that indicates that the noiseblocker is OFF.

Modules

agreeWithwarning()
                $agree = $FT817->agreeWithwarning(#);

        Turns on and off the internal flag that says. You undrstand the risks of writing to the EEPROM
        Activated when any value is in the (). Good practive says () or (1) for OFF and ON.

        Returns the argument sent to it on success.
closePort()
                $FT817->closePort();

        This function should be executed at the end of the program.  This closes the serial port and removed the lock
        file if applicable.  If you do not use this, and exit abnormally, you will need to manually remove the lock 
        file if it was enabled in the settings.
dec2bin()
        Simple internal function for converting decimal to binary. Has no use to the end user.
eepromDecode()
        An internal function to retrieve code from an address of the eeprom and convert the first byte to 
        binary, dumping the second byte.
getAgc()
                $agc = $FT817->getAgc();

        status is on, how many hours the battery is set to charge for.
getConfig()
                $config = $FT817->getConfig();

        Returns the two values that make up the Radio configuration.  This is set by the soldier blobs
        of J4001-J4009 in the radio.
getDsp()
                $dsp = $FT817->getDsp();

        Returns the current setting of the Digital Signal Processor (if applicable) : ON / OFF
getEeprom()
                $value = $FT817->getEeprom();

        Currently returns just the value you send it. In verbose mode however, it will display a formatted
        output of the memory address specified.  This was added late and will be update in the next release. 
getFasttuning()
                $fasttune = $FT817->getFasttuning();

        Returns the current setting of the Fast Tuning mode : ON / OFF
getFlags()
                $flags = $FT817->getFlags();

        Returns the current status of the flags : DEBUG / VERBOSE / WRITE ALLOW / WARNED

        Returns the current frequency of the rig eg. B<147.120.00> MHZ with B<getFrequency(1)>
getHome()
                $home = $FT817->getHome();

        Returns the current status of the rig being on the Home Frequency : Y/N
getLock()
                $lock = $FT817->getLock();

        Returns the current status of the lock function being enable : Y/N
getMode()
                $mode = $FT817->getMode();

        Returns the current Mode of the Radio : AM / FM / USB / CW etc.......
getNb()
                $nb = $FT817->getNb();

        Returns the current Status of the Noise Blocker : ON / OFF

        Returns with variables as argument $squelch $smeter $smeterlin $desc $match
        Returns with hash as argument %rxstatus
getSoftcal()
                $softcal = $FT817->getSoftcal({console/digest/file filename.txt});

        This command currently works with verbose and write to file.  Currently there is no
        usefull return information Except for digest.  With no argument, it defaults to 
        console and dumps the entire 76 software calibration memory areas to the screen. 
        Using digest will return an md5 hash of the calibration settings. Using file along
        with a file name writes the output to a file.  It's a good idea to keep a copy of 
        this in case the eeprom gets corrupted and the radio factory defaults.  If you dont have 
        this information, you will have to send the radio back to the company for recalibration.
getTuner()
                $tuner = $FT817->getTuner();

        command and posts the information when verbose(1).  

        Returns with variables as argument $pometer $ptt $highswr $split
        Returns with hash as argument %txstatus
getVfo()
                $vfo = $FT817->getVfo();

        Returns the current VFO : A / B
