(...) Dick, I was thinking more in the direction of adding a new Module, with a IOMap that has room to set a command and several parameters, and use the ReadIOMap and WriteIOMap to set them. This may not be the fastest solution, since as you (I (...) (19 years ago, 27-Jan-07, to lugnet.robotics.nxt)

|
|
(...) I was able to connect the "Get Pixel Color" command with the RCX. I run a direct program on the computer, feeding color datum to the RCX. The RCX program is set up to receive the color datum and act on it in a sequential manner. Soon I will (...) (19 years ago, 26-Jan-07, to lugnet.robotics.rcx.robolab)

Hi Claude, (...) thanks, I found it at (URL) . And pseudocode is fine with me, Java or C were just meant as examples for textual languages. (...) :-) Best is to avoid assignment and modifiable state whenever possible. Jürgen (19 years ago, 25-Jan-07, to lugnet.robotics)

(...) Hi Jürgen, The document, where I develop the theory of the algorithm has some text-pseudo code ( a mixture of C and PASCAL) that you easily can convert to anything. Since the document is math stuff, I largely prefer the := notation for (...) (19 years ago, 25-Jan-07, to lugnet.robotics)

(...) John - if you've got someone's ear in this, could you also see if a GCC build of the firmware can be released? I know LEGO are unlikely to use GCC themselves as they can afford more specialised tools, but so far, I don't see much of a (...) (19 years ago, 24-Jan-07, to lugnet.robotics.nxt, lugnet.robotics)

Hi Claude, (...) do you have the DFT algorithm in some programming language like Java or C? I'm just guessing, but maybe it could also be useful for speech recognition? Or maybe telling the cat from the dog? (The sound sensor should be usable as a (...) (19 years ago, 24-Jan-07, to lugnet.robotics)

(...) It is possible to write to the popup buffer but only by using the IOMap routine (SetDisplayPopup). The regular system calls which write to the LCD all write to the normal display memory.

(...) That actually doesn't address the real problem. The NXT has a "dongle" built-in, so it can receive the Bluetooth messages. It just can't understand what it reads. The NXT requires a very specific message format, and that's not what the mouse (...) (19 years ago, 24-Jan-07, to lugnet.robotics)

The problem is the NXT is a USB-slave device: it does not provide either the power (5V) or the communications ability to run a BT dongle (this is a seperate issue from the "shape" of the USB port: that's just a bit of hardware shaping to keep (...)
