| | | | | Expanding the available input/output ports of the RCX

| Hi, With only 3 input and 3 output ports, the RCX becomes quite limiting after a while. There are several different solutions to this at various sites. Does anyone know which one is the best out of all of them. I basically looking for good (...) (26 years ago, 7-Jul-00, to lugnet.robotics, lugnet.robotics.rcx)

| Well, Chris verifies that he uses variable 23, 24, and 25 to log values in ROBOLAB, and that he also puts in random stuff such as which sensor it is, etc. in the beginning of the datalog. But this still leaves the problem of how to clear the (...) (26 years ago, 3-Jul-00, to lugnet.robotics, lugnet.robotics.rcx, lugnet.robotics.rcx.nqc)

This would cause a sealed motor to push the air past the rotating axle. Ok, now when the motor (...) (26 years ago, 29-Jun-00, to lugnet.robotics.rcx)

| You could always check how big your datalog is by uploading the first point of the datalog in VB. The third element of the first point (point 0) is the size of the datalog. Throw that in a databox and see what it gives you. I would agree that VB (...) (26 years ago, 26-Jun-00, to lugnet.robotics, lugnet.robotics.rcx, lugnet.robotics.rcx.nqc)
