(...) I thought this was an error to, so I spent about an hour triplechecking my findings. Bear in mind that the scroll wheel doesn't need 7.5-degree-per-step accuracy, which is what that extra bit would give. This is a chart of the data I collected (...)

(...) ...or at least if you looked at 100 people who might have the desires, abilities and budget to build the beast, you'd see 100 different inventory needs. Some might have one RIS, others two, others one - plus a bunch of ad-hoc parts. I think (...) (23 years ago, 13-Jul-02, to lugnet.robotics)

(...) The header is ok, but int is 2 bytes = 16 bit. You can check this with this highly optimized program: #include <conio.h> int main(int argc, char *argv[]) { lcd_int( sizeof( int ) ); for(;;) ; return 0; } And in the kernel sources, mm.c says (...)

(...) This can't be right. I'm about 99% sure that all of the ints I've used with my legOS programs have been 2 bytes. When using LNP to send RCX ints to a PC, for example, you have to use short on the PC end of things to make it all work right. (...) (23 years ago, 12-Jul-02, to lugnet.robotics.rcx.legos)

(...) It appears to me there is a slight mistake here. According to this, there is no way to distinguish between the first row and the second. I assume the second should be 10, so it would go 00 10 11 01. Steve (23 years ago, 12-Jul-02, to lugnet.robotics)

(...) My sources (gcc-3.0) say: #define INT_TYPE_SIZE (TARGET_INT32 ? 32 : 16) A short experiment revealed that sizeof(short)=sizeof(int)=2, sizeof(long)=4. So int is normally 16bit. Only with the switch "-mint32" I get 32 bit ints. This is with a (...) (23 years ago, 12-Jul-02, to lugnet.robotics.rcx.legos)

(...) I agree with you in theory. Unfortunately, I don't have resources in optics and know very little about them (basic physics class stuff). The failure of my test may simply be related to illumination. How sensitive is the chip to reflected (...) (23 years ago, 12-Jul-02, to lugnet.robotics)

The consturction of Mibo also calls for other parts in quantities that are not as common like two (2) 6585 technic gear housings. What might be useful would be to offer all the parts that Mibo requires that are not in 2 mindstorms sets. Otherwise it (...) (23 years ago, 12-Jul-02, to lugnet.robotics)
