 | | Re: IR problems
|
| (...) I did not explain my problem properly but you got it anyway! I do use EKEY? before EKEY, but sometimes EKEY seems to block. Thanks for taking your time to look into this. As for the new word (wow!), in Forth-79, there was a word called ?KEY (...) (21 years ago, 31-Jan-04, to lugnet.robotics.rcx.pbforth)

The encoding of the IR is pretty simple. The IR tower contains a circuit (...) (25 years ago, 17-Sep-99, to lugnet.robotics.rcx)

Looking at the source, I see that there is a possiblity that in the time between checking for a character with EKEY? and actually reading it with EKEY, that an error can (...)

Things work fine if the PC initiates a conversation (e.g. by asking the RCX to send (...) (25 years ago, 23-Sep-99, to lugnet.robotics.rcx, lugnet.robotics.rcx.nqc)

It also has some timing circuitry to keep it alive, and an Rx side, but the Tx is painfully simple. You'll probably see (...) (25 years ago, 18-Sep-99, to lugnet.robotics.rcx.nqc)
