Hey, I am trying to get my computer to talk to 2 rcxs. I have the program and when I send ir messages to the RCX loaded with LegOS, it shows the IR port on. However I do not understand what the packets should look like with the intergrity layer. (...) (24 years ago, 13-Jan-01, to lugnet.robotics.rcx.legos)

|

Is there any API for switching off the rcx, either immediately or after a givent period of inactivity (i.e a watchdog) ? (already used many batteries by forgetting to switch it off...). Thanx ! (24 years ago, 13-Jan-01, to lugnet.robotics.rcx.legos)

I'm writing a program that use LNP. My addressing handler function is big, so I measured the mean time requiered for executing that function (with a call in for loop, so having sub-ms precision). Mean time: 2.5 ms, with packets of ca. 250 bytes. I (...) (24 years ago, 13-Jan-01, to lugnet.robotics.rcx.legos)

| | 0.2.5 problem
|

After installing 0.2.5, you should run 'make realclean' to get rid of some files that may cause build problems. Specifically, there is .depend file in the boot directory. This will cause a kernel build to fail since this file is specific to Luis's (...) (24 years ago, 12-Jan-01, to lugnet.robotics.rcx.legos)

One more thing, did you successfully build the program "makelx" (does cygwin use .exe extensions?). Since you could build the kernel, my previous suggestion is probably wrong. If the makelx program is missing (or can't be found by make - check (...) (24 years ago, 11-Jan-01, to lugnet.robotics.rcx.legos)
