I (another newbie) also would like to upload data from the RCX to a Windows PC. It looks like adding the data to a StringBuffer would be a good way to save it, but I have not much of a clue about how to write (1) the Java that runs on the PC to (...)

(...) I didn't think of that, but it might explain why my attemps to use the OP cods failed (they hung the RCX completely dead). Then again, I might have used them wrong... Björn (25 years ago, 22-May-01, to lugnet.robotics.rcx.java)

(...) There still could be some special rom code that is called when the opcode is called for the standard firmware. Not very likely, but still possible. Andy -- See my Visual Interface for leJOS at (URL) (25 years ago, 22-May-01, to lugnet.robotics.rcx.java)

There's no need to implement this because Java allows you to create an array and store as much data as you want in it. You have a lot more power by using an array over the NQC feature, which I believe is limited to something like 100 numbers. Hope (...) (25 years ago, 21-May-01, to lugnet.robotics.rcx.java)

I'm trying to transfer some log-data from the RCX to the PC, using the "Serial.sendPacket(byte[] aBuffer, int aOffset, int aLen)", but it does not seem to work with a packet-length bigger than approx.. 24 bytes.

Hi! I'm a leJos newbie, but at a glance, I miss the logging functions that I think NQC has, the ability to store numbers in the RCX for later upload. Is ther a chance that it will be implemented ? At least I would appreciate it Björn Lundin (25 years ago, 13-Apr-01, to lugnet.robotics.rcx.java)
