Post subject:  68K SBC Robot control unit

I am new on this forum, so hello everyone.
I'm from belgium and my name is marc.

To the point now,
I'm building a robot to do some tests in the robot club (NO war robot).
My robot is a 3 wheel robot with a robot arm to search and grip cola cans.

So I have some old 68K SBC to use with 3x 6522 VIA chips on it.
I added more RAM, EPROM and FLASH memory.
As com ports I had 2x RS232, and I added one RS485 com port.

I added 2 stepper motor control cards,
a Graphic LCD screen, some keypads.

All this runs on battery.

So, my questions,
Q1) Is there a fixed point subroutine somewhere I can use.
FP calculations are slow on my 68000 / 16MHz board.

Q2) I downloaded EhBASIC to use on my robot to easy write programs in basic with Assembler subroutines.
Can I use EASY68K for this ?

Q3) I like to make some AI subroutines.
Is there a 68K asm interpreter who is written in 68K assembler.
I like to use only my robot and a keyboard.
An no use of PC.

Q4) I need also some editor who is written in 68K asm.

You can see some photos on my website www.marc-systems.be
under the "hobby robot part" (sorry is written in Dutch)

Hi Marc,

Have you considered the original Motorola Education Board (MECB) firmware? It contains a fairly basic assembler and debugger, but it might be good enough for you to do coding within. There is more information on my website: http://www.wickensonline.co.uk/mecb.html

You'd still need a way of dumping your programs out to storage, unless you have some kind of flash ram available

Hi mark,

Thanks for the input,
I downloaded the source file and go see for the assembler.

About the memory, I have
2x 29F040 on board is about 1Mb of FLASH, to store the user programs.
2x 27C040 for the master programs is 1Mb of EPROM
2x 62C1008 is 256 Kb of RAM

Post subject:  Resident assembler

I found some information on the internet about
"MC68000 Resident Structured Assembler" software.
This is a full 68k resident assembler with use of labels and line numbers.

I like to use this software to control my robots and robot arm?
(contest is in may 2010)

Is there someone who now where to find that source code in 68k assembler.

The "MC68000 Resident Structured Assembler" is the name given to the original 68000 assembler released by Motorola. The "Resident" part of the name is a little misleading. It was not designed to be used as an embedded system. The Motorola assembler ran on VersaDos systems. I have never seen source code for VersaDos or the assembler.

If you are looking for an embedded system that will help with debugging you might want to look at the Tutor source on the Examples page under Applications.

Thanks again,

I did not now that.
The use of the "resident" is misleading.


PS: I download the TUTOR source now, thanks.
