 | | Re: How to turn LEDs on/off ?
|
| (...) I was not referring to the IR LED. I was referring to LEDs that can be connected to one of the motor ports. I believe Ross' initial response gave me the information I need. Thanks for everyone's help. -Brian (20 years ago, 10-Aug-04, to lugnet.robotics.rcx.legos)

| | Communications (I'm a total newbie by the way)
|
| Hi I've been reading the NQC guide v2.3 and I notice it tells me how to send and receive IR messages. Now I reckon I could send messages between RCX's, but how can I send messages to a program running on my PC via the IR tower (assuming that's (...)

| | Lego IR Remote - What is max send rate?
|
| I'm working on the motor key handler for legOS support of the IR remote. I'm looking at service rates of keypresses at the remote. In studying how The Mindstorms OS responds to the remote I noticed that holding the key down (for motor keys) kept the (...) (22 years ago, 27-Apr-02, to lugnet.robotics.rcx.legos)

Looking at the source, I see that there is a possiblity that in the time between checking for a character with EKEY? and actually reading it with EKEY, that an error can (...)

| | Re: Anyone know how to build a stall sensor?
|
| (...) Yes. I found on article on using the battery voltage to determine the same thing, i.e. more current, less volts. To do it you need replacement firmware. I use leJOS (a Java VM), I'm one if the developers, so I could go in that way. I'm going (...) (23 years ago, 6-Sep-01, to lugnet.robotics.rcx)

| the LNP stuff is neat, but it seem's that the remote control isn't using either "integrity" or "addressing" protocol how do I access directly the incoming IR buffer ?? I didn't see any source code for "lnp_integrity_set_handler" , how does it work ? (...) (25 years ago, 7-Feb-00, to lugnet.robotics.rcx.legos)

| | gdb & legOS
|
| Hi All. I've been thinking about how gdb can be used to debug legOS programs. I've hashed most of it out, but one thing has me stumped -- how can I do a software trap on a H8300? I'd like to hear any suggestions as to how I can get round this. The (...) (25 years ago, 17-Feb-00, to lugnet.robotics.rcx.legos)

I've toyed with this myself, and written some code (...) (23 years ago, 28-Aug-01, to lugnet.robotics.rcx)
