(...) Hello Mike, Here is a photograph (actually a scan) of all three versions (1.0, 1.5 and 2.0) of RCX: (URL) had a look at a few RCX 2.0 printed circuit boards, and at first sight they are identical. 1.0 contained the rectifier and regulator for (...)

| | RCX 2.0 circuit board changes
|

After reviewing some pictures of the RCX 2.0's circuit board today, I noticed that they are quite different. Can anybody tell me the reason why? What changed and how does it affect the RCX? I'm looking for that infamous diode that so often blows (...) (22 years ago, 30-Aug-03, to lugnet.robotics)

Natural log (ln), and square root. Also useful would be x^y where x and y have fractional parts. I see you have done it with just x as a float and y as an int. This would incorporate the square root by doing x^1/2 "nanobapt" <nanobapt@wanadoo.fr> (...) (22 years ago, 30-Aug-03, to lugnet.robotics.rcx.legos)

I've posted an enhancement request on the sourceforge website for someone to write a full math.h. I would do it myself but my programming skills aren't very good. Your math.h looks like a good start. Hopefully someone will build on that. Thanks for (...) (22 years ago, 30-Aug-03, to lugnet.robotics.rcx.legos)

(...) BricxCC is making some progress with respect to pbForth support. I've got a terminal emulator of sorts that is working. I just need to get it hooked into the rest of the application and add XModem downloading to it. By late next week it might (...) (22 years ago, 29-Aug-03, to lugnet.robotics.rcx.pbforth)

I'm having trouble finding a maths header file. It's usually called "math.h". I need to do stuff like sine and cosine, and use the "abs" function to make a number positive. Does a file like this exist? Are there any plans to incorporate a maths (...) (22 years ago, 29-Aug-03, to lugnet.robotics.rcx.legos)

(...) Yeah, I haven't quite got around to implementing cut-and-paste... You can use Hyperterminal or any other similar teminal emulator set to 2400,n,8,1 once the firmware is loaded. Unless you have a USB port. OK, if you really need this, then I (...) (22 years ago, 29-Aug-03, to lugnet.robotics.rcx.pbforth)
