I saw some programs for a palm pilot that makes it a learning remote. They were used in the same way the Lego remote was: directly controlling the rcx. I was wondering if anyone had a link for the same thing for a pc/laptop... -Rob (25 years ago, 25-Jul-01, to lugnet.robotics.rcx)

(...) I am not sure if the USB serial ports work for all applications. You might want to be a bit careful. I have some older programs which expect to find real hardware COM ports and they don't recognise the USB variety. JB (25 years ago, 23-Jul-01, to lugnet.robotics.rcx)

Lego Mindstorms told me that USB to Serial converters have not functioned properly. The actual conversation went as, "they (the convertors) don't send correct information to the brick through the IR tower. There are no work arounds." I have been (...)

(...) There are external Serial ports that you can buy and plug into your USB ports. I would think that might be the easiest way to go. Eric Kingsley (25 years ago, 23-Jul-01, to lugnet.robotics.rcx)

I can't hook up my ir tower to my new laptop, and the IR tower for MS 2.0 is not due out for another six weeks!!!!!!! My home computer finally bit the dust, so I bought this laptop Saturday without even looking at the serial port (or lack thereof). (...) (25 years ago, 23-Jul-01, to lugnet.robotics.rcx)

Dave and Luis, Thank you both for the information. I'm big admirer of the work you've done for the RCX community. (...) I see. (60/0.003)/16 = 1250 And if you were worried about the Sampling Theorem you would divide that in half just to be sure.. (...) (25 years ago, 21-Jul-01, to lugnet.robotics.rcx)

|

When using the standard firmware, sensors are sampled every 3 ms. The rotation sensor uses a quadrature encoder with a 1:4 gearing between the axle and the encoder, so there are 16 "ticks" per revolution of the axle. The decoding routine in the (...)

The hardware can actually do (in my testing) up to ~3000 rpm with good accuracy. The problem is with the standard software, which cannot do more than some low number (which may or may not be 500, I don't recall) because of how it samples the HW. (...)

Does anyone know the correct maximum sampling rate for the Lego rotation sensor? This morning I noticed that Dave Baum gives a value of 1250 RPM in his "Definitive Guide" (page 29), but looking at (URL) see a value of 500 RPM. Which is correct? (...)

The part I am having problems with is the dark-grey "foot pedal" looking part. Does anyone know what this is called or what it's used for? This has been the single biggest mystery to me since I bought the RIS kit over a year ago. (25 years ago, 19-Jul-01, to lugnet.robotics.rcx)
