(...) Actually there are four, sort of, as for 0 there are float (contacts separated, infinite resistance) and brake (contacts shorted, zero resistance). The standard firmware switches rapidly between on and float (each cycle takes 8ms), which (...) (21 years ago, 14-Jun-03, to lugnet.robotics.rcx.legos)

(...) The eight different power level pulsing is called "PWM", translation=Pulse width modulation. PWM is the way a digital chip cheats/mimics true analog without a D/A convertor. Since the only output of a digital chip is on or off, there is no (...) (21 years ago, 14-Jun-03, to lugnet.robotics.rcx.legos)

| | Varying the output voltage?
|
|
I was wondering if it was possible to control the speed/torque of the motor by varying the output voltage in brickOS. It seems that the speed parameter on the motors only changes the rate at which they pulse on and off. I am looking for something (...) (21 years ago, 14-Jun-03, to lugnet.robotics.rcx.legos)

| | BrickOS Talking to Robolab?
|

Has anyone used BrickOS to talk to Robolab? I really like the Robolab visualization tools and it would be a shame to not be able to fool Robolab into to talking to the BrickOS firmware. I am in the process of designing a simple Fuzzy controller and (...) (21 years ago, 11-Jun-03, to lugnet.robotics.rcx.legos)

Hi Ralph, I should be able to extract the source for the low level driver routines this week. If anyone else is interested, please email me. Note for BrickOS users: it's not simply a matter of plonking the routines into a program. The kernel will (...)

Scott, You need to put a .depend file and Makefile inside the directory you are compiling the programs in. Just create a file with the extenstion .depend and put it into your programs directory. There dosn't need to be anything in the file. When you (...) (21 years ago, 3-Jun-03, to lugnet.robotics.rcx.legos)

You may check out javastorms at www.javastroms.org. The project seem to be abandoned, but the code is available. Basically it does what you aim for so it should be a good starting point. I have used the code as base for some of my own projects and (...) (22 years ago, 26-May-03, to lugnet.robotics.rcx.legos)
