 | | Rotation Sensor Values —Andy Gombos
|
| | | 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)

| | | | (...) 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 (...)

|
| | | | 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)

|
| | | | 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)

| | | | (...) 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)

| | | | Hee, Hee. It was 0.2.3, not 0.2.4. Here is the code snippet that setup and read the values. The current(working) code takes out the refresh, and changes the delay to msleep. ds_active(&SENSOR_2); ds_rotation_on(&SENSOR_2); (...) (24 years ago, 24-Jul-00, to lugnet.robotics.rcx.legos)

| | | | I figured you would be glad that I was not running 0.2.4. I cannot get it to compile correctly, so I use 0.2.3 instead. The two full programs are below, in case you wanted to see them in full. Andy ----This one does not work---- #include <dsensor.h> (...) (24 years ago, 25-Jul-00, to lugnet.robotics.rcx.legos)

|
| | | | | Ack! You are still having problems with 0.2.4? I thought your problem was with the compiler, and not legOS? <flips through old Andy Gombos posts on lugnet> Is this still the merge-map problem? I figured out the situation, and fixed it in CVS.

| | | | | | I downloaded the tarball, and tried to compile it. when I an in /boot, it tries to do a genlds, and exits with an error. When I try to run genlds, it says Segmentation Error(or fault, I can't remember). I think the only reason that I can use 0.2.3 (...) (24 years ago, 25-Jul-00, to lugnet.robotics.rcx.legos)

Take it out of the loop, and I am shure this one will also work. At least with 0.2.4 it does. (...) Here the return (...) (24 years ago, 25-Jul-00, to lugnet.robotics.rcx.legos)

| | | | Oops. When I copied it, that statement got left out, and I put it bck in in the incoorect place. The original version of the code had the return in the outside loop. I know it is this way because I could turn the rotation sensor slowly, and see the (...) (24 years ago, 25-Jul-00, to lugnet.robotics.rcx.legos)
