Hi, I've just posted a v0.1.2 snapshot of the code. This adds a number of bug fixes and support for 1 bit per pixel frame buffers. A full changelog is available on the file download page. Regards, Dave |

The bug fix for ip2k-gcc are now available from the Ubicom support portal in the file downloads are. The revised 4.1.2B compiler should hopefully resolve any problems. > I have come across some displays from LC-tec in Sweden, Large diaplays that > use very little power - almost zero when not writing to them. > I have not had my fingers on them, but they seems interisting, and they > interface vis a serial IF so that should be reasonably simple to use. > www.le-tec.se have more info. Hmm - the web address doesn't appear to work for me... hmm... www.lc-tec.se seems to be it... these displays look pretty nice :-) Regards, Dave |

Hi Dave, ........> Thanks for the prompt reply, I'll wait to see the fixes/patches for now...

Supporting > controller-less displays would be even cooler, but one thing at a time :-) I have come across some displays from LC-tec in Sweden, Large diaplays that use very little power - almost zero when not writing to them. I have not had my fingers on them, but they seems interisting, and they interface vis a serial IF so that should be reasonably simple to use. www.le-tec.se have more info. keep up the good work. regards /Carsten |

While I was writing this I discovered a compiler bug which I fixed a couple of days ago. I thought I'd worked around the bug in this code but I've just realized that I didn't :-( The client colours are correct - just not very good :-) I've been meaning to add keyboard support to change the colours but I tend to only have two systems attached at any time. > Any ideas ? I need to change things to use less SRAM anyway - I'll do this and this will solve the problem. FWIW there will be a 4.0 and 4.1.2B patch for the compiler issued in the next day or so too. > and thanks for the great job - It is a very interesting project especially > if interface to local LCD's are implemented. The LCD stuff should be quite a lot of fun - I've worked with some T6963-based LCDs before now (on 8051s) and think it would be rather nice to be able to use such displays on IP2k apps. Supporting controller-less displays would be even cooler, but one thing at a time :-) Regards, Dave |

Hi Dave (et. al.) I hvae just tried to run the 1.1 version, and it compiles and run OK however I get a strange background, striped and multicolored (see attached screenshot) and the text output appears not in a regular ordered maner ;-) the screen reset (1) works ok, and painting with the mouse also OK, the lastest clients draw white and older clients with black ( tested with up to 4) Any ideas ? and thanks for the great job - It is a very interesting project especially if interface to local LCD's are implemented.

Hi, v0.1.1 of the ubicom-framebuf project is now available for download. This release contains a few more interesting features and much better structuring than its predecessor: * Renamed various functions away from VNC to RFB because the protocol is strictly the RFB protocol. * Added basic proportional font rendering mechanism. Added simple font for standard ASCII characters 0x20 through 0x7f. Added example of font use to the server demo. * Cleaned up the arguments passed to various functions. * Added some keyboard mapping information. * Started to introduce callback functions that will ultimately allow application controlled responses to RFB protocol events. Regards, Dave |
