 | | Camera Shutter Speed Measurement in Legos
|
|
I wrote a little program to measure shutter speeds and it seems to work. It uses a light sensor in passive mode to be more accurate at fast shutter speeds. I think it could be fairly accurate at even 1/1000 sec. If anyone is interested I could send (...) (22 years ago, 26-Aug-02, to lugnet.robotics.rcx.legos)

Hi everyone, I am trying to use librcx (URL) to write light (in code size) programs for RCX, and up till now it works fine, but i'd like to begin using interrupts.

Can anyone tell me if this function is blocking: lnp_integrity_write or, how can I find out when it is complete? I'm trying to do proximity stuff with BrickOS and I want to know when IR is being transmitted. Thanks Steve (22 years ago, 22-Aug-02, to lugnet.robotics.rcx.legos)

Make sure you've editted Makefile.common. The TOOLPREFIX and LEGOS_ROOT lines should point to the appropriate directories on your system, as described in the comments. Make sure that you put a trailing slash on the LEGOS_ROOT directory. -- From "The (...) (22 years ago, 22-Aug-02, to lugnet.robotics.rcx.legos)
