 | | RCX Blinking LEDs: Info updated
|
|
After a few requests, I have updated the information on adding LED's and Lamps to the LEGO RCX 'MindStorms' system. I have included info about how to calculate resistor values etc. Look at: (URL) follow the link near the top.. There is also more (...) (24 years ago, 20-Dec-00, to lugnet.robotics.rcx)

(...) My legOS.srec file, which is compiled with all the default settings, is exactly 21000 bytes long. The calculated size is 8144. Which is sort of in the ballpark of half the file size (if we use a very big ballpark). The proper estimate is (...) (24 years ago, 20-Dec-00, to lugnet.robotics.rcx.legos)

|

It seems that S@H is out of the 1.5s and they're becoming scarce in local stores. Has anyone heard of a release date for the RCX 2.0? jt -- James J. Trobaugh North Georgia LEGO Train Club (URL) (24 years ago, 20-Dec-00, to lugnet.year.2001, lugnet.robotics.rcx)

(...) Here's how to determine size given a .srec file: 1) Look at the last S1 line in the s-record file. An example from firm0328.lgo: S113E1606F... 2) Look at characters 4-8 (start counting with 0): S113E1606F... ^^^^ This is the starting address (...)

(...) I wasn't completely sure how much extra data there was in there; I knew it was larger but didn't realize by how much. Regardless, I'll merge in the changes anyway, since I don't want our tree to diverge too much from the One True tree. Luis (...) (24 years ago, 20-Dec-00, to lugnet.robotics.rcx.legos)

(...) Isn't the actual size of the kernal about half the .srec size? That file contains ascii codes for for hex bytes, a pair of characters would be one byte. Rossz (24 years ago, 20-Dec-00, to lugnet.robotics.rcx.legos)

(...) Actually, the kernel can hit 21-22K (depending on the compile-time options.) My current legOS.srec sits at 21232 bytes. So, I'm going to do the update.

When I muck about with Exploration Mars software, the RCX doesn't go out of range until it's out of the room. With pbForth, the RCX receives the commands over just as far a range, but can only send its "ok" feedback when it is quite close to the (...) (24 years ago, 19-Dec-00, to lugnet.robotics.rcx.pbforth)
