| | NXT Optimized Array Handling
|
|
There doesn't seem to be any information on the most memory-efficient or speed-effecient way to handle arrays in the NXT Executable File Specification. For example, if you want to create a multi-dimensional array, you use the opcode OP_ARRBUILD (...) (19 years ago, 28-Dec-06, to lugnet.robotics.nxt)

| | Connect BT devices to the NXT without a passkey?
|
|
Is it possible to connect BT devices to an NXT without using a passkey? The device I'm trying to use (a Nintendo Wii remote) doesn't use passkeys, AFAIK, since when I connect it to my PC I skip the pairing process. (19 years ago, 28-Dec-06, to lugnet.robotics.nxt, lugnet.robotics)

I am using a Compaq (HP) nc8000 laptop which has a built-in BT device and it works fine with Windows 2000, so BT should be OK on W2K (with the right device).

(...) As explained on our pages, I am using CORDIC algorithm. This assures best accuracy and converges much more rapidly than Taylor. There is one trade-off though, because there is no bit shifting operation in the toolkit, I must do division (...) (19 years ago, 23-Dec-06, to lugnet.robotics)

|

Maybe a cheap sollution, but if I have to draw a sine or cosine I wouldn't calculated. Well, I will calculate it once and put it in a table. Then draw the sine & cosine from the calculated coordinates from the table. Really fast. And, euh, nobody (...) (19 years ago, 23-Dec-06, to lugnet.robotics)
