 | | FORTH editor/IDE
|
|
Is anyone considering, or in the process of, writing an editor for pbFORTH on the PC? I am thinking of doing one in the style of RCX Command Center ((URL) but don't want to reinvent the wheel if there's one on the stocks. I haven't tried pbFORTH (...)

(...) 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 (...)

(...) 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)

Thanks to all of the mail I have received, I am going to try to get the next version of pbFORTH out this weekend.

I decided to try playing around with pbforth, and one of the first things I try after Ralphs testpb is to turn on the the little guy. So I type 3006 LCD_SHOW LCD_REFRESH and zip zero zilch nada. So I go looking through the code and find that (...) (26 years ago, 3-Mar-99, to lugnet.robotics.rcx.pbforth)
