 | | pbFORTH needs better uploading, docs
|
| So I've just been crawling over some broken glass, ERR, I mean, uploading pbFORTH text files to the RCX! It's hard to tell the difference! At the least, pbFORTH needs to: 1) accept \n, \r, \n\r or \r\n all as it does a single \r now. 2) have a mode (...) (25 years ago, 8-Jan-00, to lugnet.robotics.rcx.pbforth)

| | Electrical Data Link between 2 RCXs
|
| The following describes an "electrical data link" (one direction) between 2 RCXs (see also my subject "Connecting 2 RCXs"). The task is that one RCX sends a number (e.g. a status) to another RCX via a cable. The IR link cannot be used because they (...) (24 years ago, 25-Oct-00, to lugnet.robotics.rcx.nqc)

The same things can be done with event driven single task code but it inverts the control flow. It is more meaningful for most (...) (24 years ago, 3-May-00, to lugnet.robotics.rcx.pbforth)

| | Re: Powered Sensors

| No, the RCX knows nothing about the diodes. That is why devices like the light sensor only send a current signal in the range 0 - 0.32mA back to the RCX. This current then creates a voltage drop across the 10k reference resistor with respect to the (...) (22 years ago, 7-May-02, to lugnet.robotics.rcx.legos)
