 | | [Q] LEGO NXT Book Recommendation
|
| Greetings- What single book, if any, is considered the standard for LEGO NXT? -David (17 years ago, 29-Jan-08, to lugnet.robotics)
| | | | | New Power Functions Electronics Folder
|
| The new Power Functions Electronics folder in my Brickshelf: (URL) contains circuits and pictures of how to use electronics with your PF parts. So far there are PF lead mods, a light direction, latch and flash circuit, which can keep train lights on (...)

|
| A new version of my Power Functins library and PWM remote are now available at: (URL) There was some code cleanup and fine tuning. The PWM remote program now goes from slowest to fasted speed. give it a try and thanks for all the feed back so far. (...)

| | | | | Re: Power Functions infra-red RC protocol released!
|
| (...) Very good. Have you done experiments to map the power level settings to RPM? I am guessing that each of the 7 steps sets literally a power level (PWM width) and not a speed. Have you done experiments under load to see what happens to the speed (...) (17 years ago, 27-Jan-08, to lugnet.technic, lugnet.trains, lugnet.robotics, FTX)
| | | | | Re: Power Function control with RCX and BrickOS
|
| (...) Could it be that the long range mode of IR is not set (I saw no reference to range setting in your source, and I don't know the default state). Despite the difference in carrier frequency, the RCX 1.0 and RCX2.0 are able to dialog albeit with (...) (17 years ago, 27-Jan-08, to lugnet.general, lugnet.technic, lugnet.trains, lugnet.robotics)
| | | | | Re: Power Functions infra-red RC protocol released!
|
| (...) I just tried the new commands with a home-made NXT-controlled IR remote. I was able to get them to work without a problem. I verified the single-output PWM mode, which starts a motor at a given power level, in which it stays indefinitely (...)

|
| (...) i have not really spent a lot of time trying to figure these modes out. i was more concerned with getting the PWM to work correctly. i'm going to spend more time testing this and will let you know. bob (17 years ago, 26-Jan-08, to lugnet.general, lugnet.technic, lugnet.trains, lugnet.robotics, FTX)

|
| (...) Glad it worked for you and thanks for the heads up on the RCX 2.0 problems. i don't have a 2.0 RCX to play with so i'm not sure if it is a timing issue that can be resolved or what. i was very excited the first time i got my RCX to talk to the (...)

| | | | | Re: Power Function control with RCX and BrickOS
|
| (...) Well this was just a quickly hacked out example program to show how to use the library function that i wrote. i realized at the time that the PWM started out at fastest and went to slowest but i had run out of steam and never really got back (...)
