I've just released a new version of BricxCC. This release add support for downloading non-standard firmwares (such as pbForth). I've also added support for several languages other than NQC with user customizable syntax highlighting. These languages (...) (23 years ago, 7-Mar-02, to lugnet.robotics.rcx)

I'm re-posting this message at the lugnet.robotics.rcx level in case anyone missed it. I've put together a stand-alone application which I am calling ForthPad.

Thanks. I have a version just 2 words longer that doesn't use the ROM code. Basically it's the ROM's code, trimmed down after assuming high words are zero initially. It's completely untested though, so there may be a bug. CODE UM* \ 16x16=32 (...) (23 years ago, 4-Mar-02, to lugnet.robotics.rcx)

(...) The easiest thing is to cast your 16 bit values to 32 bits and use the built-in 32x32 multiply... Here's the code from pbForth that does it.

I'm trying to implement a 16bit multiply that leaves a 32bit result on the H8/300. The RCX ROM includes 16x16=16 and 32x32=32 multiplication routines, but not the intermediate step.

(...) If the motor runs on 9V anyway, just hook it up to RCX directly (assuming it only draws 500ma). If it needs more than that, hook an external battery up to it via a power transistor (either bipolar or FET). You'll need a resistor in series with (...)
