To: Multiple recipients of list PICLIST PICLIST@MITVMA.MIT.EDU

I am announcing the beta release of MacPIC, a Macintosh program for editing, assembling, simulating, programming, and disassembling programs for the PIC17C series of microcontrollers. Full simulation of all ports, the USART, timers, the works is included. MacPIC is shareware, a $25 fee is requested from those who find it usefull.

The MacPIC program will drive the Warp-17 programmer from Newfound Electronics, giving it a Macintosh driver. As far as I am aware, this is the only way to program PIC's from a Mac.

Files can be transferred from PC works, including text or hex files.

The code can be downloaded from ftp://ftp.srv.net/pub/users/kxc, which has four files - MacPIC_68K.sea.bin, MacPIC_68K.sea.hqx, MacPIC_PPC.sea.bin, and MacPIC_PPC.sea.hqx, which are for 68K and Power PC based Macintoshes, MacBInary II and BinHexed versions respectively.

Support for more PIC types, more programmers, and other requested features will be forthcoming.

And in a later message to me Kevin said:
High priority on version 2 of MacPIC is PIC16 support, including the warp-3.

Thanks Don for the quick response. Your concern is valid. I've based
my order on information I've gathered from the internet.

Your site led me to: http://www.dontronics.com/macpic.html

Which led me to: ftp://ftp.srv.net/pub/users/kxc

Which contained the following and several applications.

MacPIC

The MacPIC shareware program is a tool for editing, assembling,
debugging, and programming the PIC microcontroller.  All functions are
contained in one program for an integrated development environment.  The
following is a short list of major features.

Editor: 
WASTE based editor.  Import and export text and hex files from/to other
editors or PIC programming tools.  Unlimited program size.  Drag-and
drop editing.  Full clipboard functionality.  Word jump cursor keys.

Assembler:
Multi-pass assembler with labels, symbols, include files, and define
macros.  Error list tied to list window and editor for easy corrections.

Disassembler:
Recreate source from hex files or device programmer reads.

Simulator:
Unlimited breakpoints.  Register value watchpoints.  High simulation
rate (~200kHZ chip simulated in real-time on 100MHz PPC).  Port pin
control while simulation running.  Serial Port (USART) data display. 
Serial port data reception from data file.  Stack View window. 
Run/Step/Break control window.  Full register set, stack, and EEPROM
data viewing during program breaks.  Ability to change register values
during simulation.

Programmer:
Drives serial port programmer for blank check, write, configuration word
write, data EEPROM write, ID location write, device read, and device
verify operations.

Here is the most important part

Programmers supported:

     Warp-17 by Newfound Electronics
     Warp-3 by Newfound Electronics
        Deck Programmer by Francis Deck


Elsewere I found instructions for making a Warp-3 to Macintosh serial
port cable. So I'm led to believe that everything exists. At least I 
am hopefull.

Hi Kevin,
        Our emails crossed, your copied on latest one to Don, and I've
taken the liberty of copying him, and Jim. I see what your doing, biasing
the Rx+ to 2.5V rather than gnd, should garantee reception of the logic
level. This is much better than just reversing the leads, which seems to
work but maybe marginal.

It's always good to hear that other's have preceded with success.
