| (...) hi Juergen I tried it with load, and it works much better! Only that the speed is not very stable in the curves. (...) If i use a cycle of 10ms, then i could only use 10 different speeds, because the Thread.sleep has a resolution of 1ms... (...) (22 years ago, 8-Jul-04, to lugnet.robotics.rcx.java)

| From the picture (d1_p31) it looks as though all 4 RCXs can see the tower. I don't know anything about pcrcxcomm.jar or rcxf7port; and not much about lejos, however, if all 4 RCXs try to respond to the tower, you will have collisions. Try covering (...)

| Hi everyone, Im working on a project with controlling a large Container Crane by 4 RCXs. I have implementet some controlling and a lot of functions in the model, including a userinterface made in Java for a laptop. The crane is controlled by a (...)

| (...) There is a fundamental difference between the RCX and a Lego Train controller - the controller uses smooth power from a 3-pin regulator, with the voltage varied using a chain of resistors. The RCX uses PWM power with approximately 166ms square (...) (22 years ago, 3-Jul-04, to lugnet.robotics.rcx.java)

| hi I want to use rcx to control a lego train, but the fact that lejos only have 7 levels makes it dificult to set the speed. Jürgen Stube wrote in september2001: "Yes, the standard LEGO routines make it very hard to control speed. Basically with an (...) (22 years ago, 28-Jun-04, to lugnet.robotics.rcx.java)
| | | | | RE: Bluetooth and firmware query
|
| Mike, If you're interested, pbForth replacement firmware may be the answer for many of your issues. My serial driver for the RCX is a straight half duplex that turns off the receiver when transmitting to avoid echoes from the IR. It could be (...)

| As some of you may know, we have been hacking RCXs and adding bluetooth modules. What would make life easier is some help modifying the firmware to increase the speed of the serial protocols to the max the Hitachi chip can handle, which is a lot (...)
