Hi! Just my 2-pence thoughts about the topic... I suppose nobody will argue with me that legOS isn't well documented, as it is now. Considering that legOS is still rather user-unfriendly, documentation is very important. someone said Markus is (...) (25 years ago, 28-Jan-00, to lugnet.robotics.rcx.legos)

Why don't you use the system timer (sys_time)? With one timer is enough. Use relative times instead of absolute timers...

Before anyone replies to my previous message, found the problem. I have a light over my desk and this was interfering with the IR transmission. Turned the light off and moved the RCX a little closer to the tower and hey presto, all OK. Does legOS (...) (25 years ago, 27-Jan-00, to lugnet.robotics.rcx.legos)

Hi I installed the win version of legOS and downloaded the firmware legOS.srec to both my RCX's. The older RCX from a 1.0 set seems to accept .lx files OK the first time after the firmware is downloaded. The new version will not accept any .lx (...)

I did some more experiments last night. My conclusion is that the majority of apparent 2-state transitions never actually occur (that is: the sensor does not actually travel through 2 states between two consecutive sensor readings).

Probably related to the garbage on the lcd that you get when turning off the RCX with a sensor active: if there is a light or rotation sensor or a pressed touch sensor connected to the RCX when you download firmware legOS will crash immediately (...)
