  Re: Ir transmission
 
(...) I can't get EMIT to work, in NQC I do this: SendMessage(255); // Flash Sleep(3); ThisRaw = RAW_LIGHT; and the raw light sensor reading has big spikes for IR reflections. but: [ HEX ] FF EMIT 30 msWait RawLight LIGHT? does not, I think that (...)

  Re: Ir transmission
 
(...) Well, in the spirit of FORTH there should be no finite number, just create and destroy them on the fly as and whan you need them. I have been wandering around the internet looking and found that hForth has one already: \ hForth multitasker \ \ (...) (25 years ago, 17-Apr-99, to lugnet.robotics.rcx.pbforth)
 
  RE: Ir transmission
 
(...) I think its around 16 Mhz for the crystal and 4 MHz for the cycle time. I think there is a msec timer buried in the OC1A handler (see Kekoa's disassembly) I agree that we want something to trigger a run flag instead of having to check the (...)

  Re: Ir transmission
 
(...) The bytecode interpreter does it, which is what NQC maps to (opcode 43). I'd prefer a timer (or access to a clock) with millisecond resolution rather than a delay because things will get interesting whan multitasking. What is the CPU clock (...)

  Re: SENSOR_READ doesn't return 0
 
(...) Well, I think your progress so far is very good, I can understand the odd slip-up, it keeps us on our toes. If I get anywhere with the LCD constants for the complicated segments I'll let you know. (...) Because I am trying to reproduce (...) (25 years ago, 16-Apr-99, to lugnet.robotics.rcx.pbforth)
