SAVING CODE AND DATA BASIC SECTION 3

UPDATING OR REPLACING RPBASIC-52

RPBASIC-52 program may be update d or replaced w hile

in circuit. A current version of RPBASIC-52 for the

RPC -210 is on the ap plications disk. It is also available

at our web site at www. rp3.com . Check under

PRODUCT S, then RPC -210.

Your own assembly language program may replace

RPBASIC-52 also. In either situation, the process is the

same.

First, download the Basic program HEXLOA D.BAS.

This program accepts Intel HEX files and stores the

binary information in RAM segment 1, starting at

address 0.

After the program is loaded, execute the BSAVE

command:

BSAVE 0,0,1,0,6000H

Saving 6000H bytes takes a couple of seconds.

NOTE: You will need to hit the reset button to restart

or run your program. This is because the burn

program runs from RAM and will try to return

to the calling address. This address may have

changed.

WARNING:

The BSAVE pr ocess is irr eversible. Once started it

cannot be stopped. If power is removed during the

saving process, chances are your program w ill be

“half bur ned” and probably unusable. In that case

you will need to burn in the 29C 040A Flash

EPROM in an external burner.

NOTE: If the program you are replacing does not have

its own Flash EPROM saving program , any

subsequent changes to the Flash must be done

using an external burner.

BSAVE does a verify. However, if you are replacing or

updating RPBASIC you probably will not get an error

message. If replacing RPBASIC-52, download and run

VERIFYRP.BAS to make sure the entire program

burned OK.

SETTING FLASH SIZE

Jumper block W4 sets U6 size. By default, RPC-210

boards with RPBASIC-52 are shipped with 512K of

Flash. W 4 jumpers should be set to W4[1-3][2-4] for

standard boards.

COMMANDS

The following is a list of RPBASIC-52 commands used

with RAM and Flash EPROM.

Command Format

BLOAD Transfers data from EPROM to RAM

BSAVE Transfers data from RAM to EPROM

CALL Calls an assembly language routine

PEEK B Returns a byte

PEEK F Returns a floating point number

PEEK W Returns a 16 bit number

PEEK $ Returns a string

POKE B Stores a byte to RAM

POKE F Stores a floating point number to

RAM

POKE W Stores a16 bit number to RAM

POKE $ Stores a string to RAM

XBY Reads or writes external mem ory,

segment only.

NOTE: BSAVE syntax will change in future

versions (in or about 2012) to include an

“E”, or erase sector option.

1 2 ... 12 13 14 15 16 17 18 19 20 21 22 ... 59 60
