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 (...) (18 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 (...) (18 years ago, 23-Dec-06, to lugnet.robotics)

now we have a complete integer trig-function package. Challenge : who is going to draw the first sine and cosine waves on the NXT display? Please report any bugs. www.convict.lu/Jeune...sIntro.htm Claude (18 years ago, 22-Dec-06, to lugnet.robotics)

Hi interested, LV toolkit is amazing ! It allows writing cool blocks. Now we have the arctangent function... for integer numbers !!! f(x)=atan(x) You enter x as milli_x. Example: 1000 milli = 1 !!! The result of the function is deci-degrees, a (...) (18 years ago, 21-Dec-06, to lugnet.robotics)

There is a lot of "not quite standard" to existing USB capable products. Some things like digital cameras and thumb-drives get along fine with current operating systems, but most of them have their own drivers available to implement extra features. (...)
