(...) SENSOR_1 gives you the raw value from sensor 1. TOUCH_1 gives you the boolean value if it's a touch sensor. In fact SENSOR_1 gives you the raw value no matter what type sensor it is. HTH ROSCO (23 years ago, 21-Apr-01, to lugnet.robotics.rcx.legos)

Hello, Can you access the raw touch sensor values in legOS? I know you can do it in NQC but I haven't figured it out in legOS. Thanks in advance, Nate Ridderman (23 years ago, 21-Apr-01, to lugnet.robotics.rcx.legos)

Hi Matt, i had the same problem. That's a Microsoft *feature* ;-) that comes with visual C++ 6.0. (This problem is described in the MSDN. If you've got it installed, you 'll find details there.)

(...) This should be "struct tNode *next;" (...) After this, any time you want to refer to a tNode, you need to say "struct tNode". Or you can put "typedef struct tNode tNode" and then use the "tNode" as a type like you're doing. (23 years ago, 12-Apr-01, to lugnet.robotics.rcx.legos)
