 | | DATALOG and C —Brandon Yates
|
| | | Hi all, Could someone write a C program that just hangs out and waits for the RCX to send a datalog to it? RCXLOG is great but not quite what I need. RCXLOG.exe Tells the RCX to upload a datalog, prints it out, then quits. I'd like something that (...) (25 years ago, 23-Jan-99, to lugnet.robotics)

The RCX won't do anything thing like that from a program. The UploadDatalog (...) (25 years ago, 23-Jan-99, to lugnet.robotics)

Since the IR tower automatically powers down a few seconds after transmitting data, you will not be able to receive data unless the C program (...) (25 years ago, 23-Jan-99, to lugnet.robotics)

| | | | | | | There is no way that the RCX can explicitly start an upload, it has to be requested by the PC. There is no problem however aquiring your goal with messages or variables. The best way I have found to achive your goal is to let the RCX signal to the (...) (25 years ago, 24-Jan-99, to lugnet.robotics)

| | | | (...) I see your point about UploadDatalog, as the tower falls asleep and the PC won't hear the RCX shouting. But SetDatalog seems to work in a program just fine, to set the size of the datalog buffer. BTW, what is the maximum size for the datalog, (...) (25 years ago, 25-Jan-99, to lugnet.robotics)

If that is true then, if you put the command in with some downloadable RCX instructions, it does whatever it does right then and is not actually sent with the RCX program. (...)

If you want to figure this out dynamically from the PC, get the memory map after downloading all programs to the RCX. The maximum datalog (...) (25 years ago, 25-Jan-99, to lugnet.robotics)
