16.5Command: “c”
The control command is used to send commands to the copier. The possible control commands are as follows:
Capture print engine | (10h) |
Release print engine | (11h) |
Print setting | (12h) |
Print pre feed | (13h) |
Capture scan engine | (14h) |
Release scan engine | (15h) |
Scan setting | (16h) |
Start scan | (17h) |
Preheat/Shutdown rls | (1Fh) |
Ctlr scan data err | (80h) |
Ctlr print data err | (81h) |
Ctlr err rls | (90h) |
All of the control commands are described in the interface document and will not be described in detail in this document. In general, the user must enter the HEX number corresponding to the command to be issued. After the HEX number is entered, LBTEST will prompt for a timeout value, which is in 100 MSEC units. For example, if a timeout value of 200 is entered, the timeout is actually 20 seconds. Two hundred (200) is generally a good value to enter for the timeout. The timeout value is used by the Littlebear controller to determine if a control command completed on time.
For commands that take arguments (see the interface spec), such as the Print setting (12h) command, all of the arguments need to be entered, one line at a time. The LBTEST program requires that six arguments be entered even if the command does not take six arguments. In this case, enter 00 for the remainder of the arguments that are not used. After the six arguments are entered, a timeout value will need to be entered, as described above. All arguments are in HEX, except for the timout value.
16.6Command: “i”
This command is used to do two things:
1)Clear the Littlebear data FIFOs.
2)Clear the Littlebear controller status flags.
After entering “i”, LBTEST will prompt for a HEX byte value. This value is used to determine which of the above operations to perform. Bits 0 and 1 of the value are currently the only bits used; the other bits have no effect. The bits are mapped as follows.
bit 1 = (1) initialize controller status byte, (0) no effect. The controller status byte is explained in the Command: “s” section.
