Hi All, I am working in Lejos, which I've found to be a great environment to get working (on Windows 98) and to work in, and have a problem. In earlier versions of Lejos(at least according to the docs), and Tinyvm, objects persisted across runs. I (...) (24 years ago, 30-Mar-01, to lugnet.robotics.rcx.java)

Thanks. Now I have converted wav file to mono data sampled at 11025Hz (can be changed) and sample range is 0-255 as below: 144, 150, 154, 156, 160, 159, 154, 149, 143, 134, 128, 120, 110, 103, 97, 93, 91, 93, 96, 102, 110, 120, 127, 138, 149, 156, (...)

This has been asked many times before, and while it seems like it should be possible in theory, it's not possible in practice. The reason is that the speaker is connected to one of the special outputs of the H8 processor which is designed to pulse (...) (24 years ago, 29-Mar-01, to lugnet.robotics.rcx)

I can't figure out how to use the IR commands. I've tried, read a bit in the documentation, but still have no clue. I'd like to know how to: a) Send a message (and decide what message it should be) and b) learn how to recieve messages Thanks in (...) (24 years ago, 29-Mar-01, to lugnet.robotics.rcx.nqc)

I think it's an excellent idea... I saw the barcode system being explained some years ago and I still think it can be the most accurate.
