MOTM

Quick thoughts.

1) I plan to code in assembler, because

a) the assembler is *FREE*
b) the C compiler is $800
c) I have written over 600,000 lines of 8051 assembler code and 0 lines of C
code
d) I have *already written* 1/5th of the Seq code 1.0 already

2) The assembler code source will be posted to *encourage* hacking. People
not hacking the code
will be made fun of :) (Hack #1: have your name scroll across the display at
power-up).

3) Yes, you can turn it into a

a) ADADRSRDDARDR.... EG
b) LFO
c) MIDI-2-CV
d) Sampler (!!?! heee hee)

I plan to license the Keil Software (www.keil.com) Rom-based debugger. This
is a ~3K
program that is in every Seq. It talks to a serial port, and to a W95-based
program. This program
allows you to

a) download the assembled code (Intel HEX format)
b) single-step it
c) disassemble it
d) run to a breakpoint
e) dump register & memory contents

So, you can find bugs pretty easily *without* a decicated "evaluation board"
or "ROM emulator".

Pardon my ignorance, but how do you get it to talk to the PC when
MIDI is 31.25kbaud? Plus, how do you single-step if the 8051
is looking for MIDI clock on the serial in? Or are you going
to add a 6250 UART?

You go Paul. I think even I might be able to handle this (after you
explain to me how it works). HAHA

The part has 2 serial ports.

Go Paul!

I've been avoiding learning *any* programming skills
but this seems like it may be a worthwhile project.

I know the Seq is months away, at least I'll have plenty of time to
procrastinate.
