 | | My RCX doesn't work!
|
|
I haven't used my RCX for a while, I found it doesn't work when I want to download firmware to it today. In fact, it is near non working! The RCX2 tools, nqc, lejos and WinNQC all can't find this RCX, but it can be found in 1% chance even if I put (...) (24 years ago, 23-Feb-01, to lugnet.robotics.rcx)

(...) Thats great! I have a working GCC cross compiler for the Agenda (A Linux Based PDA (URL) ). The little box uses standard /dev/ttySx so I suspect the porting will go well. This means I will have the tower hanging off the PDA, but I really hope (...) (24 years ago, 22-Feb-01, to lugnet.robotics.rcx.nqc)

(...) I'm not familiar with the Agenda, but if you have a gcc compiler for it, several hundred K of heap space, and basic file I/O, then the port of NQC itself generally comes down to one thing: serial interface class (platform/PSerial_xxx.cpp). For (...) (24 years ago, 22-Feb-01, to lugnet.robotics.rcx.nqc)

| | equiv. to SetRandomSeed() for firm0309?
|
|
Is there a way to do the equivalent to SetRandomSeed() with 1.x firmware (3.09) which--if I understand correctly--is only available for RCX2 (3.28)? Maybe some kind of low level code to set the appropriate memory address? Thanks, Rik. (24 years ago, 22-Feb-01, to lugnet.robotics.rcx.nqc)

(...) of (...) The call looks fine, but as Bernado said, you have to make sure that higher priority tasks relinquish control regularly. IIRC all tasks of a given priority must get a slice before any lower priority tasks get any slice. And remember (...) (24 years ago, 21-Feb-01, to lugnet.robotics.rcx.legos)

(...) That line seems ok to me. Setting priority for a task above 10 (normal priority) may cause starvation to other tasks. This depend on what your function process() does. If it never waits (using calls like wait_event(), sleep(), sem_wait()...) (...) (24 years ago, 21-Feb-01, to lugnet.robotics.rcx.legos)

Hi Folks, I have used the RCXCC under windows for quite a while, but now I am quite taken with my shiny new Linux install on my desktop and my Agenda linux PDA.

| | multiple "execi" with different priorities
|

Hi, I am trying to run three different tasks, with the "execi" command. When all of the have the same priority=10, everything works ok. When I change the priority in one of them priority=11 or 12, then everything seems to go much slower, and (...) (24 years ago, 21-Feb-01, to lugnet.robotics.rcx.legos)
