 | | RCX Firmware Speed —Dick Swan
|
| | | This is a follow up to many of the recent posts on the speed of Lego's RCX byte code interpreter. It's a long post but the salient items are in the first few paragraphs. The interpreter is very slow because of all the overhead required to execute a (...) (23 years ago, 10-Apr-02, to lugnet.robotics) !

| | | | Dick, Nice post, and an iteresting topic. My timings differ a little for v2.0 beta, but they are basically the same. My timings use an interal timer as do yours. My multi-task measurement shows that the 3mS framework does not apply to every (...) (23 years ago, 10-Apr-02, to lugnet.robotics)

| | | | Thanks Ralph, this is great news. I just got the new USB tower, and considering my revived interest for pbForth your new version arrives really at the right time. What IMHO would really boost the spreading of pbForth, is the availability of some (...) (23 years ago, 10-Apr-02, to lugnet.robotics.rcx.pbforth, lugnet.robotics.rcx)

|
| | | | Mario, i'm interested in pbForth example scripts, too. Furthermore, the "supervisor" you suggested could be the answer to one of my questions in (URL) concerning turning the RCX off and on without loosing pbForth: 2) According to Knudsen, i have to (...)

| | | | (...) If you have the new version 2.1 the POWER-OFF word via terminal to shut off and the red button to power on works fine. If you have an earlier version (1.2x) you have to use the words RCX_INIT and POWER_INIT to initialize the brick and the (...)

But I find not very practical to be forced to use the terminal to switch off the RCX or start the program again, expecially when you are attending a contest or take your robot to an exhibit.

| | | | I need to look at some items for Joerg, but I'll also look at a small supervisor that integrates the View,Run,Prgm,and On/Off buttons.
