(...) It's not a race condition, strictly speaking. It's more of a data sampling error. If you run that it a tight loop you will test the sensors hundreds or thousands of times a second. In order to see a simultaneous press you'd have to hit them at (...) (25 years ago, 29-Dec-99, to lugnet.robotics.rcx.legos)

| | Re: touch sensors - two at a time ?

(...) If I understand your problem correctly, it has nothing to do with legOS specifically. Therefore, I will answer, even though I have no experience with legOS. The problem is, there is a very small amount of time where, while you're pushing on (...) (25 years ago, 29-Dec-99, to lugnet.robotics.rcx.legos)

| | touch sensors - two at a time ?
|
|
I'm trying to build a sensor apparatus at the front of my bot, and it works, mostly. It's made up as a pair of touch sensors. The idea being that if one is activated, it turns around slightly, to avoid the sensor, but if both are activated, we (...) (25 years ago, 29-Dec-99, to lugnet.robotics.rcx.legos)

(...) It is 1/10 of a second for the timers. However, in case you don't know. The RCX's Motor ports PULSE their signal. They always put out the same voltage. At level 8 it's 100% at level 4 it's an even on/off. I use it for my trains and it's great. (...) (25 years ago, 23-Dec-99, to lugnet.robotics.rcx, lugnet.trains)

Hi All, Since I am and train head I don't read .RCX (this topic might be well exhausted) I just read thru a third party book on the RCX and in one place he said the timer granularity in 1/10 sec and in another it was 1/1000 sec.
