(...) Just for the record, I implemented a dual-speed downloader a few months ago and mailed John Tamplin with information about it with regards to the JVM port that seems to have died. I used a different strategy to hack the dual speed downloads. (...) (25 years ago, 3-Oct-99, to lugnet.robotics.rcx.legos, lugnet.robotics.rcx)

| | egcs-1.1.1 patch, legOS projects structure
|
|
Hi, this night is proving productive. I went ahead and tweaked egcs to produce RCX-specific interrupt handler prologues and epilogues. Apply this patch against egcs-1.1.1/gcc/confi...0/h8300.c, and you will be able to create interrupt handlers the (...) (25 years ago, 3-Oct-99, to lugnet.robotics.rcx.legos)

(...) Not at all ;-) fast.srec works like this: - load new image, storing it immediately behind fast.srec - fix stack pointer, you'll start new firmware anyways - relocate a small routine immediately below SP - call that routine - relocate the (...)

I'll have to try fastdl at some point. My pbFORTH image is assembled to live at 0x8000 and be loaded just like "real" firmware. If I use fastdl, how do I have to change my firmware assembly output to accomodate it? On the subject of configurable (...) (25 years ago, 3-Oct-99, to lugnet.robotics.rcx.legos)

(...) Erm, hrm, well... the reason I didn't ship it yet is that it won't compile with any released version of legOS. In order to gain full configurability, I had to set up a seperate directory structure, with its own include tree and stripped down (...) (25 years ago, 3-Oct-99, to lugnet.robotics.rcx.legos)

Looks real nice on the PC side, Markus, but- where is the source for fast.srec? Was that a deliberate omission? Or just a mistake? I'd really like to look at what is in there, especially considering the small size of the .srec. Let us know... -Luis (...) (25 years ago, 2-Oct-99, to lugnet.robotics.rcx.legos)

Hi, I'm currently implementing LNP. As a first demo application, I just finished a quad-speed firmware downloader. If you're using replacement firmware, maybe this will be of use to you. (URL) you at MindFest, Markus. (25 years ago, 3-Oct-99, to lugnet.robotics.rcx.legos, lugnet.robotics.rcx)

On the subject of making connector blocks, I have been very successful with taking the conductor strips you get as a S@H service pack, hacking two squares out, slotting one edge of each of the 2x2s, soldering wires to that side, slotting the inside (...)

Thanks, Jonathan && Others... I'll look at the patent. With all the 'clones' out there, is it likely that Lego would complain if someone made compatible-but-not- identical connectors?? How do they handle the Clone Market?? Couple of questions, (...) (25 years ago, 14-Sep-99, to lugnet.robotics, lugnet.robotics.rcx, lugnet.robotics.rcx.legos)

I tried solutions posted on this newsgroup to fix the rotation sensor problem.But It didn't work stable enough. I tracked the sensor input and realized the sensor sometimes picked up transient signal between two states. To solve this problem, I (...) (25 years ago, 10-Sep-99, to lugnet.robotics.rcx.legos)
