 | | Battery voltage levels
|
| I have two RCXs: a version 1.0 with external power connector, and a version 2.0 without. They consistently report different voltages on the same batteries: the 2.0 puts all batteries about 0.3v higher. I want to know how much variation there is (...)

I was hoping for a report from someone who was ultimately successful in building legOS and its tools, as well as building the cross-compilers on a USB OS (...)

| | Re: IR tower problems on a laptop with NQC
|
| The light goes on as soon as you plug in the tower? Sounds like someone is already using COM3. I was looking around DELL technical support and you may have a bit of work ahead of you. First off your serial port on the inspiron 8200 should be COM1. I (...) (20 years ago, 9-Mar-07, to lugnet.robotics.rcx, FTX)

If the light is always one I would look for another application that is trying to use the serial port. (...) (20 years ago, 12-Mar-07, to lugnet.robotics.rcx, FTX)

| I also figured out what COM3 was: the internal modem. I disabled it in Device Manager and now the only port that I can find in my C# app or in Hyperterminal is COM1, the serial port. But the IR tower is still not working. By the way, the built-in IR (...) (20 years ago, 10-Mar-07, to lugnet.robotics.rcx, FTX)

But then it reports the error I provided earlier. (...) (20 years ago, 13-Mar-07, to lugnet.robotics.rcx, FTX)

| I feel kind of dumb: the serial port was disabled in the BIOS.

After some apparently common problems, I managed to compile the h8300 programs and compile legOS 0.2.2. The demos work as (...) (27 years ago, 22-Nov-99, to lugnet.robotics.rcx.legos)
