I have a TI M4 MCU on order.


Did you know the Ti Stellaris chip doesn't have a PWM (Pulse Width Modulation) unit?  It doesn't matter because ARM has a lot of timers but you will have to learn to do things differently.

Iggy,

I just joined this forum very recently, and I was pleased to find your post :)

Thank you for liking my Morpheus design! (and also finding PropCade)

I have rev.2 Morpheus PCB's now with some additional features... unfortunately my site is sadly out of date as consulting and family come first. I also had to put Largos on the back burner.

Morpheus now has a lot of graphics drivers, including 320x240 256 colors
per pixel, with sprites, signaled as 640x480 VGA, as well as VGA/SVGA/XGA with 4 colors per pixel (separate palette for each scan line)

You can program propellers now in Spin, assembly language,
C, C++, Forth, various versions of Basic and more.

Actually, my days with the Amiga inspired me to create Morpheus.

I picked up Amiga Forever today!

Maybe I should dig out my Amigas (two A1000's, one signed by Jay Miner) and an A500... but wifey might kill me if I set up any more computers & monitors... better just run Amiga Forever on PC's....

I've been studying the idea of using MCUs to emulate older computers or as substitutes for glue and I/O circuitry.
 
Right now one of my favorites is the Parallax Propeller.
http://www.parallax.com/propeller/
 
Its a 75-100MHz 8 core 32bit MCU.
Each core acts as a 'cog', has video generation capability, and is seperately programmable.
 
So far, users have programmed the Propeller to do useful things like generate VGA signals, interpret PS/2 keyboard and mouse input, and emulate a SID chip.
 
Currently, a group of developers is working to emulate a C64.
 
I'd like to work with this chip alone AND combined with older CPUs (like the 6809, 6309, 68K, and Coldfire).
 
This is the board I'm starting with:
http://www.mikronauts.com/morpheus/
 
Dual Propellers and enhanced memory.
 
My first project will add a 63C09E, some static RAM, an SD card reader, and a serial port to the system.
 
I'd like to incorporate dual SID emulation as well.
 
Eventual the Morphues board will support a 256x192 256 color screen mode with sprites.
 
It already supports much higher resolutions (although with fewer colors).
 
I can program the Morpheus with Parallax's own Spin under Morpheus' built in OS Largos.
 
So, eventually, I hope to have a system that will marry the 6309 specific NitrosOS9 operating system with some very capable MCU hardware and software.
 
What do you think?

There is more powerful stuff out there which is why a lot of the mobile phones have ARM in them.  ARM is really the true successor to the 6502 Chip.


What makes you say that?

(btw, seems there's not Propeller with more than 20 MIPS/cog still..)
