(...) Mario, Lejos supports communication using the original firmware opcodes via the Serial class, but, apart from program download, this is designed for executing opcodes, not downloading data. F7Handler and F7DeliveryHandler are part of and (...) (24 years ago, 1-Dec-02, to lugnet.robotics.rcx, lugnet.robotics, lugnet.robotics.rcx.java, lugnet.robotics.rcx.robolab)

Hi all, we are working on our final thesis using lego mindstorms. Our goal is to implement a neural network using the backpropagation algorithm. This neural network will then be used with a webcam for pattern recognition and classification. The (...)

Hello People I am working on a project where we are trying to use a compaq handheld with linux and a wireless card as the "brain" of robots. "Underneath" we have an RCX acting as a "spine", which is supposed to receive macro commands from the PC and (...) (24 years ago, 21-Nov-02, to lugnet.robotics.rcx.java)

(...) Daniel, Much more than the 600 byte class gets downloaded. If you do lejos myclass -o myclass.bin, and look at the size of myclass.bin, you will see the true size of the download. If you have a serial rather than usb tower, then you can use (...) (24 years ago, 11-Nov-02, to lugnet.robotics.rcx.java)

hi first, i would like to congratulate the Lejos team. When i bought Mindstorms, didn't imagine i was going to use it with my favorite programming language! I noticed that Lejos (2.0.0) is very slow to download programs or firmware to the rcx, (...) (24 years ago, 11-Nov-02, to lugnet.robotics.rcx.java)

Does anyone of you know, whether it is possible (with a special byte sequence for example) to send a command to the running LeJOS JVM on the RCX which tells it to run a certain uploaded program? Or, if not, is it maybe possible to call a program x (...) (24 years ago, 25-Sep-02, to lugnet.robotics.rcx.java)
