| | Curious problem with download
|
|
I just got Mindstorm set, and since I do not have a PC, NQC seemed like a great place to start. I tried Mac NQC and did not get very far downloading the RCX firmware. Every attempt resulted in the IR tower not seeing the RCX. I have a G3 blue and (...) (25 years ago, 27-Jan-00, to lugnet.robotics.rcx.nqc)

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). The order of the (...) (25 years ago, 27-Jan-00, to lugnet.robotics.rcx.legos)

Hi! Did anyone write any 'nicer' wrapper functions for handling the RCX timers? Or am I blind and can't find them? 8^) /Vlad (25 years ago, 27-Jan-00, to lugnet.robotics.rcx.legos)

(...) I've only verified pbForth being uploaded using the commandline version of NQC. (...) This is good. Has anyone else out there tried RCXCC to upload the pbForth firmware????

(...) more light and is working.... Erm... it isn't really working - it exhibits the same 'inverted' behaviour, looking for a white line on a black background... /Vlad (25 years ago, 27-Jan-00, to lugnet.robotics.rcx.legos)

Hi! Maybe this is obvious for all experienced legOS users - I am displaying the values read from the light sensor on the LCD, and I get values of ~30 for light and ~520 for darkness... This seems very strange - is it the display wrong, or are these (...) (25 years ago, 27-Jan-00, to lugnet.robotics.rcx.legos)

I have replaced my batteries without erasing the firware several times. The trick is replacing the batteries one at a time with the brick turned off. You have then several (10 or so) seconds between each replace. If you leave the brick switched on (...) (25 years ago, 27-Jan-00, to lugnet.robotics.rcx.legos)
