Hi Lou, the sleep instruction effectively shuts down the CPU until the next interrupt occurs. Thus, the idle process conserves battery power if no task wishes to run. I consider this a worthwile feature. If you can do this without a dedicated idle (...) (26 years ago, 8-Mar-99, to lugnet.robotics.rcx.legos)

| | Idle process
|

I am reworking parts of the task scheduler in tm.c, tm.h, et al. I notice, reading the code, that there is an idle process which runs all of the time. There is a note in tm.c; "execi needs pd_idle". It appears to use it to locate the head of the (...) (26 years ago, 7-Mar-99, to lugnet.robotics.rcx.legos)

Is anybody doing work on the scheduler (tm.c et al)? I've got some ideas for a minor rewrite and don't want to collide with anybody else's efforts. -- No honest business is promoted by spam with the possible exception of Hormel. (26 years ago, 2-Mar-99, to lugnet.robotics.rcx.legos)
