7.5 SCRIPTI PROGRAM
This program is designed to send any number of 1 or 2-byte commands to the
Z86230. The list of commands to be executed are contained in Script files that
have the extension .SER. For example, a file called FILFA.SER contains the 1-byte
command:
{C5, 02} * Set xds filter to all future class
The program is invoked by typing: SI File_name <ENTER>
NOTE: File_name without the .SER extension.
The screen displays:
EEG CCD2 Serial Interface Script Player Version x.xx
Slave Address is 28h
Script File Done
The responding slave address is reported to the screen. When all of the commands
in the file are successfully sent to the Z86230, the PC returns to the system
prompt.
The program checks the RDY status before sending each byte. If, during the entry of
a command, the RDY bit is not found to be a 1 after an extended wait, the program
reports the contents of the SSR and then continues checking for RDY.
7.6 SCRIPT FILES
Script files can be generated to perform all of the setup and control functions
required to use the part in an application. The script files shown in the following
pages are examples used to set up the Z86230 for different operating conditions.
Some of the files contain only a single command while others include several
commands. The user should refer to Z86230 Commands and Registers Summary
for details. Although the following examples are organized according to a particu-
lar register, some of the files contain information for several registers.
