| | SetClock defined
|

I noticed that the byte code command to implement the SetClock(hrs,min) wasn't implemented in the nqc.h file. Here it is, rather simple really but I find it useful as a way for the RCX to communicate debugging info while running. Example, when a (...) (26 years ago, 16-Mar-99, to lugnet.robotics.rcx.nqc)

(...) 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 (...)

Hi All, If this is old news, ignore it... I just figured out this weekend (thanks Kekoa) that the H8/300 stack pointer (r7) and the power-down function in the RCX have a close relationship. The stack pointer MUST be in the on-chip RAM area (0xFD80 (...) (26 years ago, 15-Mar-99, to lugnet.robotics.rcx.legos, lugnet.robotics.rcx.pbforth, lugnet.robotics)

Just wanted to inform everyone of a nastly little NQC bug in version 1.2: return statements in inline functions actually cause a top-level return from the enclosing subroutine / task.
