 | | Palm Pilot and the RCX
|
| Hi folks, all you Palm owners out there, don't forget to check out the lugnet.robotics.palm newsgroup. The earlier problem with BrickRemote and LRemote turned out to be the server. The programs work fine now that they are in a .zip file. See: (URL) (...) (25 years ago, 17-Nov-99, to lugnet.robotics.rcx)
| | | | | rotation sensors
|
| Hello, one of my beautiful new rotation sensors was jammed right out of the box. I built a robot to try out dynamic equilibrum, i.e., balancing a weighted stick, only to notice that my construction didn't turn at all because of sensor friction. (...)

| | | | | dkey_multi (was: Kernel dies after loading)
|
| (...) Now I know what makes the RCX freeze: On my RCX , the variable dkey_multi, which stores the status of the keys, always has the first bit (0x1) set. This causes the debounce loop at boot up to hang, because it thinks that the On-Off key is (...) (25 years ago, 17-Nov-99, to lugnet.robotics.rcx.legos)
| | | | | Re: Serial Comm with RCX
|
| Well, it's hard to say what the problem might be. Since you've got the green LED going, you've probably got the cable wired correctly. And yes, it's 2400 baud, 1 start, 1 stop, 8 data, odd parity. Perhaps the packet isn't correct. Here's a sample (...) (25 years ago, 16-Nov-99, to lugnet.robotics.rcx)

| (...) I have to comment here that the O'Reilly "The Unofficial Guide to LEGO® MINDSTORMS™ Robots" (By Jonathan B. Knudsen, 1st Edition October 1999, 1-56592- 692-7, Order Number: 6927, 266 pages, $24.95) is one of the best "tech" books I've read in (...) (25 years ago, 16-Nov-99, to lugnet.robotics.rcx.legos)

|
| Garry- I can't speak to your problem specifically, but you may actually want to try to make the HP speak directly to the RCX, skipping the IR Tower altogether. Someone claimed to have done this months ago, but never posted any code, so I have no (...) (25 years ago, 16-Nov-99, to lugnet.robotics.rcx)
| | | | | Serial Comm with RCX
|
| I am trying to connect my HP49 Calculator with the Mindstorms IR Tower, I thought I had got the protocols right, the Green LED lights when I send the packet but nothing else, no reply from the RCX. Am I missing something?. Protocol 2400 baud odd (...) (25 years ago, 16-Nov-99, to lugnet.robotics.rcx)

| Look what I got in the mail today: two rotation sensors, courtesy of O'Reilly. Thanks, guys! Now to fix that driver for good... Markus. (25 years ago, 16-Nov-99, to lugnet.robotics.rcx.legos)

| (...) There was a report at one point that someone could get the cross-compiler running on Solaris, but that never materialized. My own half-hearted attempts built binutils (a beta version which might not have actually worked anyway) but never made (...) (25 years ago, 16-Nov-99, to lugnet.robotics.rcx.legos)
