 | | Data-transfering RCX -> PC in LeJOS

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. The packet is constructed as a (...) (25 years ago, 18-Apr-01, to lugnet.robotics.rcx.java)

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)

The PC could also do some processing on the data to make the RCX's (...) (25 years ago, 30-Mar-01, to lugnet.robotics.rcx.java)

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 (...) (25 years ago, 30-Mar-01, to lugnet.robotics.rcx.java)

I'm a tad fuzzy on working without GC. If I create objects in an inner loop, is that memory lost? Will I not hemorrhage memory like a sieve? (25 years ago, 1-Mar-01, to lugnet.robotics.rcx.java)
