This excersise provides description of the PC based application and requirements related to this application. The app is expected to join all the previously explained components together. Mainly it will use these parts:
The final application will be named: NucTer.
The application will allow for:
This section provides some advices related to single tasks.
The application will allow to pass these paramters on the command line:
The standard output will be used for user interaction. The error output will be used to report problems with serial port access (open, read, write, close) and commands problems, e.g. wrong command reporting: lab10.
The input data set is just a list of commands in a text file which will be read one by one and send to the device. The responses will be available through standard and error output.
The flow control file will alow for usign the predefined data sets and sending specific commands to the device in relation with the user actions - mainly the joystick movements.
The flow control file is divided into sections:
// comment line #label:PartA: //start of a block #label:PartB: #label:PartC: #label:PartD:
Every section will use a set of commands
// comment line #label:PartA: //start of a block *IDN? LED OFF #goto:PartB: #label:PartB:
or the commands can be read from external file
// comment line #label:PartA: //start of a block #include:InitDataSet.txt: // the TXT file contains just a list of commands, e.g.: "*IDN?\nLED OFF\n" #label:PartB:
The flow control is controlled mainly by the joystic unit
