(...) However, last night, I wrote a brute force (spin loop) msleep which works fine in the scheduler. I found that 800 iterations of an empty for loop with a 16 bit index comes pretty close to 1ms. Granted, I cheated a little, knowing that the (...) (26 years ago, 17-Mar-99, to lugnet.robotics.rcx.legos)

(...) Oh, you're doing stuff inside the scheduler. Yeah, msleep doesn't work too well there :-) Yes, the pauses were only so I could see what was going on. Another thing you could do is print messages out the IR port; but I'm not sure how it would (...) (26 years ago, 17-Mar-99, to lugnet.robotics.rcx.legos)

(...) I don't think it does. Of course, the source would answer definitively, but I also know that until I remembered to put the refreshes in there, I didn't get useful output. (...) I did that too. In my case, the lower byte was the priority (...) (26 years ago, 16-Mar-99, to lugnet.robotics.rcx.legos)

(...) That's the method I've used. Just be sure to put an lcd_refresh() after the cputw() call - I can't remember if cputw() does the lcd_refresh() or not. Another thing I've done is write out a number where the upper byte indicates a position in (...) (26 years ago, 16-Mar-99, to lugnet.robotics.rcx.legos)

(...) To be more precise, it applies to sleep mode and software standby mode as long as you set port 5 bit 2 to high before activating either mode. It does not apply to hardware standby mode, since that does not save registers or end with an (...)

(...) After talking with Ralph over the weekend, I suggested a test he might do to figure out if port 5 bit 2 really does what he suggested it might. I don't think he did this test, so I fired up my RCX and hacked it together. I verified that port 5 (...)

Do you guys have an established mechanism for debugging? I'm thinking of writing certain numbers to the display using cputw(). The idea being that the number frozen forever on the display will be the (approximately) last place the code was ok before (...) (26 years ago, 15-Mar-99, to lugnet.robotics.rcx.legos)

(...) Markus, (and anyone else listening) I think it applies to the RCX power_shutdown() function as described in Kekoa's reference. The key is that this function puts the external RAM into low-power mode. If you are not calling power_shutdown() or (...)
