But you need to do a bit more if you're using the RCX. We used that scheme when we (...) (19 years ago, 29-Dec-05, to lugnet.robotics.rcx.legos)

| I do think Steve is on the right track here. The train regulator varies the voltage, but the RCX output can't. So you are left with managing (nominally) 9v pulses. But there is another solution. You could add a DCC decoder to your train motor, and (...) (19 years ago, 29-Dec-05, to lugnet.robotics.rcx.legos)

| (...) hi Steve, I think the problem is not exactly the same. The lego technic motors run always at the same speed so you need to use that kind of schema for speed control in robots. The train motors are different, they have a speed proportional to (...) (19 years ago, 29-Dec-05, to lugnet.robotics.rcx.legos)

| (...) Daniel, One problem you'll run into with most software is that it switches between power and float to adjust the motor levels. It works much better to switch between power and brake. Using most software, the train will continue to speed up, (...) (19 years ago, 27-Dec-05, to lugnet.robotics.rcx.legos)

| A couple of years ago, i used brickOS. Then, i changed to Lejos... I have a moc where i use the RCX to control a train with a lego train motor. It is difficult to control the train with LejOS, because it only has 8 output levels. Two solve the (...) (19 years ago, 27-Dec-05, to lugnet.robotics.rcx.legos)

| Hi, I have been trying to get brickos to compile on my linux machine. I followed the instructions here: (URL) used binutils version 2.16.1, and gcc version 4.0.2. The cross compile seemed to work. However, when I try to compile brickos, I get the (...) (19 years ago, 22-Dec-05, to lugnet.robotics.rcx.legos)

| (...) I'd agree that a physical block is the easiest, although there is a software solution. The RCX can not recieve a command while it's transmitting - so if you saturate the transmitter with things to do, it will not be able to "look" for any (...)
