SAVING PROGRAMS SECTION 3

Page 3-2 RPC-330

The time it takes save a program depends upon the

length and complexity of the program and flash EPROM

type. Programming rate is roughly 600 bytes/second. If

the program is not successfully saved to EPROM, an

error message will appear.

Saving a program overw rites the pr evious one. There is

no way to recover the old one since both occupy the

same space.

Using SAVE without any parameters is the same as

typing SAVE 0.

When a 512K (29C040) EPROM is installed in U6, the

SAVE segment parameter is 0 - 7 (512K). EXECUTE

loads and runs the program in the segment specified by

SAVE. A 32K (29C256) EP ROM can run just one

program.

Make the following modifications to the above program

as instructed to see how one program can call another.

There must be a 512K EP ROM installed to run this

code.

Add the following lines:

10 PRINT "Program segment 0"

60 EXECUTE 1

Now type:

SAVE 0

Now m odify lines 10 and 60 as follows:

10 PRINT "Program segment 1"

60 EXECUTE 0

Now type:

SAVE 1

To see the programs operate, type RUN. To stop program

execution, press < Ctrl-C> .

You may notice there is a slight pause between the

printed hello' s and program segment number . This is

the time it takes to clear memory and load the program.

Loading and clearing take appr oximately 0.25 seconds in

a very small program and several seconds in a very large

program.

AUTORUNNING

To autorun a program:

1. Make sure there is a program in EPROM (from

above). When using a 512K size EPROM, make

sure the start up program was saved to segment 0.

2. Remove jumper W9.

Push the reset button. The program will run. If there

are any error s, the program will stop (assuming you

have not trapped them with ON ERROR) and display the

error m essage. EX ECUTE n may be used w ithin any

program to load and run another program. The EPROM

size must be a 128K or 512K.

PREVENTING AUTORUN

When troubleshooting a program, it' s not always

convenient for an autoexecute file to r un. This is

especially true if the program has been configured to

ignore the < ESC> or < Ctl-C> keys.

To prevent autorun, install jumper W9 before power up

or reset.

LOADING A PROGRAM

There are tim es when y ou may w ish to tempor arily

modify or otherwise test out a change to a program.

Since the program is loaded into RAM in autorun,

modifications can be made without affecting the program

in EPROM. Use the LOAD or LOAD n comm and to

transfer the EPROM program to RAM.

If you find out that modifications are not desirable or did

not work, you can restore the original program to RAM

using the LOAD command.

CHANGING EPROM SIZE

The RPC-330 normally comes with a 32K or 512K flash

EPROM . The size may be changed at any time. Set

W2 according to the type/size.

Type Size W2

Bytes Configuration

29C256 32K [3-5], [4-6]

29C010 128K [3-5], [2-4]

29C040 512K [1-3], [2-4]

1 2 ... 7 8 9 10 11 12 13 14 15 16 17 ... 47 48
