Scripting provides an alternate method of creating and editing I2C messages for use in the JI-300
application environment. Messages are constructed using a simple text editor such as Windows
Notepad. The JI-300 scripting language includes both I2C commands (Read & Write), and JI-300
instructions (Stop, Comment, etc.) Script files are loaded into the JI-300 application and executed as
conventional I2C messages.
5.1 Language Statements
I2C Commands
1. I2C Write

message list.
5.2 Scripting Rules
1. Script files shall contain plain text. Files can be created using a simple text editor such as
Windows Notepad.
2. Each statement must be terminated by a Carriage Return followed by a Line Feed. All simple
text editors insert these control characters automatically when the line is terminated by the
Enter key.
This exercise will familiarize the user with scripting fundamentals of the JI-300.
The JI-300 application provided two script functions: Import and Export. Import reads a script file into the
I2C Message List and Export writes I2C messages from the Message List to a script file. These functions
are located at the File tab at the main window bar.
The best way to get started creating scripts is to first create a sample I2C message using the standard
I2C message entry method (i.e. Add Message Window). This I2C message (or messages) will be used as
a prototype or model for other I2C messages that need to be created. Next, export this message using
the Export function to create a script file. Using a text editor, open the script file and begin editing. Simply
cut, paste, and copy I2C messages to change the desired message parameter(s) (i.e. slave address,
direction, data bytes, message function, etc.) Finally, import (using the Import function) the newly created
script file into the JI-300 application to check for syntax error, and to execute messages.
Follow the steps below to begin the scripting exercise.
1. Begin by launching the JI-300 host adapter application.
2. At the main window, click the Add Message button to open the Add I2C Message window.
3. Add the following two messages to the Message List (see section 2.4, step 5 for help in
adding messages)
1.
a. Message Type: Write
b. Slave Address: A0
c. Data: 20, 30, 31, 32, 33
d. Remove Stop: No
2.
a. Message Type: Read
b. Slave Address: A1
c. Read Count: 4
d. Remove Stop: No
4. When complete, verify that the message list has been populated as shown below:
MSG # Addr N/S R/W Data ASCII Status
001 A0 W 20 30 31 32 33 0123
002 A1 R
XX XX XX XX
5. Next, create a script file by clicking on the Export function. This function is located beneath
the File tab at the main window bar. Click File, followed by Export, followed by I2C Messages.
6. The Save As dialog box is now displayed. Type in an appropriate file name such as “JI-300
Script1” and click Save.
7. The I2C messages contained in the Message List are now saved to script file “JI-300
Script1.txt”
8. Now, using Windows Notepad, open the newly created script file.
9. Verify that the file contains two lines of text as shown below:
Figure 14. Script File
10. Using the Scripting Language Statements in section 5.1, decode the two lines of text and
verify that it is the same as those entered into the Message List.
11. Next, copy and paste the two text lines back into the Notepad window. Repeat this three
times. Verify that eight lines of text are displayed as shown below:
JI-300
12. Now, edit the lines of text as follows:
1. Line 3:
•Remove the Stop from this Write message by replacing character
‘w’ with ‘y’.
2. Line 4:
•Remove the Stop from this Read message by replacing character
‘q’ with ‘d’
3. Line 5:
•Change the slave address of this Write message from A0h to B2h
by replacing “A0” by “B2” in character locations 2 and 3.
Two types of drivers will be installed: Virtual COM Port (VCP) and Direct Drive (D2XX). The VCP
driver allows control of the JI-300 adapter via ASCII serial commands sent using a terminal
emulation program such as Windows Hyper Terminal. The D2XX driver allows direct access to a
USB device via a DLL interface. Both drivers are supplied by the manufacture of the USB interface
