 | | time control : BrickOS versus the RCX standard OS ?
|
| Hi list, I'm trying to implement a position regulation (using a motor and a rotation sensor), using for instance a PID (Proportional-Integr...erivative) regulation. I tried to code it in NQC, using the standard OS, but it seems that the RCX standard (...) (20 years ago, 17-Sep-05, to lugnet.robotics.rcx.legos)

| I'm changing the subject line in the middle of the thread. Wonder what the server will do with that... I tried out Brian's "Max-picking" ping method, as well as a few other things. Here's a summary of what I found: 1) If the active sensor readings (...) (20 years ago, 16-Sep-05, to lugnet.robotics.rcx.nqc)

|
| (...) Correct. A NQC command (say, "Wait(10);") is converted to one or more "bytecodes" (in this case, one bytecode, namely a string of 4 bytes (0x43 0x02 0x0a 0x00), the first of which is a command (0x43) while the following three are information (...)

| Hey, Thanks for all the helpful responses, everyone. Brian: (...) I guess that "firmware" must be the code that tells RCX how to interpret user instructions (NQC, C, IC, opcodes, or whatever), and convert them to binary machine-specific code. Right? (...)

| (...) And that explains why I was having so much trouble with my custom Tcl based uploader in high speed mode. I fixed it a while ago by adding a slight bit of extra time between messages, but never got to the root of the problem. Thanks Dick! (...) (20 years ago, 15-Sep-05, to lugnet.robotics.rcx)
