Hello, I recently bought the LEGO mindstorms Invention System kit and I am trying to get brickOS v0.2.6 working on my PC (Win98). I also have the USB tower. So far, I have found 4 bugs in the current script. I was able to fix 3 them or work around (...) (23 years ago, 13-Dec-02, to lugnet.robotics.rcx.legos)

The motor handler is only called once ever 2ms in the latest version of BrickOS (as opposed to every 1ms in earlier versions). This is a fairly recent change and it could be causing a "granularity" type problem with certain speed settings in your (...) (23 years ago, 12-Dec-02, to lugnet.robotics.rcx.legos)

|
|
I'm having a problem, and I hope someone can help me. I've been running winLegOS, and I've switched to the latest version of BrickOS. I created a way to control the motors, which will reliably speed them up, and slow them down by using different (...) (23 years ago, 12-Dec-02, to lugnet.robotics.rcx.legos)

| | sys_time (long post)
|
|
As I was poking around in the BrickOS kernel, it occurred to me that using the sys_time variable isn't entirely safe. Since sys_time is 32-bits and the processor can only read 16-bits at a time into a register, there is a period of time between the (...) (23 years ago, 12-Dec-02, to lugnet.robotics.rcx.legos)

(...) You already have an RCX 2.0. Aside from printing "RCX 2.0" on the plastic, the RCX in RIS 2.0 is identical to the one included in RIS 1.5. Since you have downloaded the 2.0 firmware, you should be all set. Dave (23 years ago, 11-Dec-02, to lugnet.robotics.spybotics)
