Sharptool's user guide

Sharptool is basically a command line tool, so it has to be launched from a terminal. Unfortunately, for the moment this interface is a bit rude as there is not fancy things implemented a la gnu's ReadLine but command can be grouped in scripts.

Shortcuts

Commands


Emulated machines

Starting script

At startup, sharptool tries to open a file named .sharptool in your home directory : the main usage is to define a startup environment.

As example, my own file contains only :

@ ~/scripts/PC-1350

which will configure the emulator to act as a ... PC-1350. Have a look in script sub directory : it contains some scripts for supported architectures.

Sharptool understands following commands :

Help commands

? or help

help displays the list of all known commands.

man

man displays the online help of a command :

man : Gets info about a command.
man <cmd>

Memory related commands

load

Loads a binary file in main memory. Optionally, base address can be specified.

loadB1 is doing the same bug loads files in bank1 memory (created for PC-2500 emulation).

peek & poke

Idem as BASIC counterpart. The only difference is with poke where values are space separated.

Notez-bien : those commands ignore memory kind or protection. In other words, poke can modify ROM and peek can read lower 8k. It's expected for debugging purpose.

disassemble

Disassembles the memory :

search

Search some data in memory :

search <address> data

where

Example :

PC-1350> sea &8000 "GOTO"
Found : &A721
PC-1350> du &A721
A721 474F544FC6C1C6E5:6B 'GOTO '

Labels related

deflab

defines a new label

deflab &6C30 FixedVar

loadlab

loads a label definition file. Labels files are compatible with asm tool.

Emulation related

call

Runs a program at the given address. The emulation will stop as soon as the called program returns. The GUI is not started.

boot

boot up the emulated machine with GUI enabled. A full reset is assumed.

powerup

boot up the emulated machine with GUI enabled as if the machine is power up.
Note : it's mostly useful when a full memory image is loaded or if the pocket has been previously started and powered off. Otherwise, sharp ROM usually does a full reset if system's memory is not initialized.

machine

Defines the machine type.

Without argument, displays the list of known models :

PC-1350> machine
*I* Known machines :1350 1350K 2500 2500K

trace

Traces instructions as they are executed.

ignore

Assumes the screen is always on.

On machines where LCD is always enabled as PC-1350 or 2500, it will speed up the emulation (on real hardware the screen blink when the machine is idle in order to save the battery).

miscellaneous commands

@

executes a script. All commands defined in this page can be used in a script.

echo

outputs a message.

status

shows the status of the emulator.

PC-1350> status
*I* ----- Current configuration ------
*I* verbose is desactivated
*I* the checksum of binary file is verified
*I* 24 lines are displayed
*I* The LCD is always ON
*I* the machine type is 1350
*I* Current home directory : '/home/laurent/projets/sharp'

verbose

enables additionnal information to be displayed.

home

specifies the root directory where sharptool can find files. The initial value is the current directory.

prompt

Changes command line prompt.

bye, exit or quit

exits sharptool

Emulation Generalities

Key mapping

First of all, sharptool code is not very clever up to now in term of host keyboard handling. Especially, it focus mainly my own environment and expect a full 101 key QWERTY keyboard ...
As it's a bit boring for my AZERTY machines or for laptop without numeric keypad. I'm thinking to use implement a graphical keyboard ... in preparation of poket with large keyboard as PC-1401.

Sharp's pockets use keys that don't exist on a standard PC keyboard. To bypass this issue, the following key mapping is done :

In addition following keys rise some special feature :

PC-1350 emulation

PC-1350 special key mapping

PC-2500 emulation

PC-2500 special key mapping
