Yes, but even if all active sensors are turned of we are running with a lot of CPU power due to the high sampling speed. If you lower the (...) (24 years ago, 24-Jul-00, to lugnet.robotics.rcx.legos)

(...) That's a good question. Is this the latest tarball? If so, there have been some modifications to the refresh loop, and this may indicate a bug in them. In other words, it could be the double sets of lcd_refresh() and not the actual reading (...) (24 years ago, 24-Jul-00, to lugnet.robotics.rcx.legos)

I added back in the display code, and left out the lcd_refreshes. Then I got a proper counter. I wonder why the refresh was throwing the reading off. Thanks for all your help, Andy (...) (24 years ago, 24-Jul-00, to lugnet.robotics.rcx.legos)

(...) I've used the OC1B interrupt for my servo driver code in pbForth. You could use the OC1B to set the settle time for each reading, and then actually read the results when the interrupt expires.

(...) That's good. Now I wonder about some other questions: - Will it get the same value as the original firmware? - Will be influenced by offset (eg. from battery voltage)?

Well, I do not know if I have to have code to display the values. I do not get anything on screen when I run this code. If I put a loop, and with every loop, the sensor value is being displayed, then I get the values mentioned before. I run the (...) (24 years ago, 24-Jul-00, to lugnet.robotics.rcx.legos)

(...) Andy- Have you set up the rotation sensors correctly? You need to do a few things before you get reasonable values for the rotation sensor. 1) use ds_active(&SENSOR_1) to turn on the sensor. 2) use ds_rotation_on(&SENSOR_1) to turn on the (...)

I was reading about rotation sensors for legOS for a new robot, and thought I'd try it out. So, I made a simple program that would show rotation sensor values on the display. What I got was not what I expected. I have never used the rotation sensors (...) (24 years ago, 24-Jul-00, to lugnet.robotics.rcx.legos)
