SphinxOS - latest version?

Bill Henning · 2012-10-31 12:06

Hi guys,

I am working on demos for a couple of my products and I have a couple of questions:

1) which is the latest version of SphinxOS?

http://forums.parallax.com/showthread.php?114023-Sphinx%E2%80%94as-seen-at-UPEW!/page10

message #188, "SphinxOS v011c" the most up to date version?

Or is there an even newer release somewhere?

I modified the version on sphinxcompiler.com to run on PropCade a while ago, and now that I want to get it running on a few more of my boards I want to make sure I start with the latest code base.

2) Is there an editor I can use for SphinxOS that can support a text display of 80*25 or 30 columns?

I'd like to use it with my single cog 80 column driver.

Thanks,

Bill

The latest version I've see is from June 2009. I have some later versions with specific modifications like for the C3 SPI selection mechanism and some changes in the display driver,

I'm not aware of an editor for an 80 x 25 display. The existing display driver keeps the video buffer in the cog to save hub space. I assume your driver keeps the buffer in external RAM.

The June '09 version is the one I used before; Cluso posted a version on February 25/2010 in the thread I linked - that's the latest I was able to find. I was hoping someone knew of a newer version.

I also found a "tools" thread at http://forums.parallax.com/showthread.php?114210-Tools-for-Sphinx&p=821109#post821109

No, my driver uses the hub for the buffer and the font; I was hoping to find an editor that used an SPI ram for the text buffer.

Hmm...

I can:

1) try to find the time to write such an editor

or

2) declare such an editor to be "impossible", thus causing it to be born

Thanks Mike.

Preditor from Casslan is using a gap-buffer on the SD-card. It only needs to keep some sectors in memory. It was using a VGA driver, don't remember which screen-size.

Thanks! I'll check it out.

I have been busy lately and hardly around. I was working on an OS version that used Kye's SD driver and the work Drac did to make KyeDos. I stripped the commands back to separate programs called under the OS. This makes it easy for others to add OS commands.

However, it doesn't run the same as Sphinx. I wanted to also be able to use Michael's Sphinx compiler on the prop. But for this to work, I needed to make part of Kye's SD driver resident. I have not had the time to do this yet

Maybe later this month although I have been saying that for a few months now.

Here is a link to the OS I was working on last and use regularly. http://forums.parallax.com/showthread.php?138251-A-Propeller-OS-that-can-run-on-multiple-hardware...&highlight=propeller+os
Latest code is at the end. It uses Homespun to compile and there is a batch compile file to do it in one step. No external RAM is required, just a basic prop and SD card. Currently uses the USB connection via P30/31 though this is easily changed.

SphinxOS - latest version?
