 | | The datalog
|
| Can I have the computer read the datalog after a program is finished, and then, depending on what the datalog reads, have it download a different program to the RCX? My idea would be to make a robot that stores it's movement, and thhen have the (...) (24 years ago, 30-Sep-00, to lugnet.robotics.rcx.nqc)

The NQC command can read the datalog (printing it to stdout) and download programs, but to do something intelligent you'd need another (...) (24 years ago, 30-Sep-00, to lugnet.robotics.rcx.nqc)

| So I can just return the datalog to the computer, not have NQC choose different programs to download depending on what the datalog reads? BTW, in firware version 2, the RCX can read from the datalog, but what does that mean in reality? Can it decide (...) (24 years ago, 1-Oct-00, to lugnet.robotics.rcx.nqc)

|
| Um, OK, but since Perl is a bit out of my league, I think that I will hold it there. But maybe I'll learn Perl in the future, who knows? Do you think it could be done in AppleScript? (Is MacNQC scriptable, BTW?) Guess there's an easy way to check (...) (24 years ago, 1-Oct-00, to lugnet.robotics.rcx.nqc)

| Someone in RTL said the RCX firmware ver 2 could read the datalog too. I read your documentation first since I figured you would have added functionality to NQC for that. I didn't see it in NQC. Then I check LEGO's docs but didn't see it there (...) (24 years ago, 2-Oct-00, to lugnet.robotics.rcx.nqc)

| (...) Dave, I have a question about the datalog. In the manual you state that the createdatalog function creates a datalog of x many points. How much is a point? Is that how many unique entries can be made or an overall 'byte' amount? Is a value (...) (24 years ago, 3-Oct-00, to lugnet.robotics.rcx.nqc)

| (...) Each call to AddToDatalog() uses up one "point". Each point takes up 3 bytes of memory: a 1-byte code for the source of point (sensor, timer, etc), then a 2-byte value. 123456 is too big to fit into the log. This would either generate a (...)

For example, AddToDatalog(Timer(1)) adds the current value of Timer 1 to the log and also stores that this entry came (...) (24 years ago, 5-Oct-00, to lugnet.robotics.rcx.nqc)
