Sometomes our gyro stops reading values and just randomly counts up. We have changed cortexes, changed gyros, changed three wire cables, changed ports, and changed code, and nothing helps the gyro consistently read values for more than a few meetings.
Does it start doing it while driving? I only noticed this happen when the cortex was plugged into a computer via USB cable. To get the gyro to stop counting, turn off the cortex and unplug all the batteries including the 9v and power expander then turn it back on.
I have had this happen on two different occasions. 1 time, our gyro was not plugged in, so I figure it isnt that one. However, if you move the bot while the gyro is “calibrating” then it will believe that turning at that exact speed is standing still, so that it will report a turning value when not moving
It normally counts up i haven’t noticed it count down but it could be. “Counting up” means the gyro will read values like: 200, 2480, 6932, it counts very fast (around 50 degrees a second) and with no noticeable pattern.
It normally starts the counting while the robot is turning.
We will be testing autos running it over and over and then all of a sudden when it turns it wont stop and when i display the gyro values it shows it counting.
We have tested the gyro screwed in, on rubber bands, and just hanging from a cable all count at some point.
gyro has been high and low on the bot. no wires near gyro.
Stupid question but is the light on it green? We (by we I mean ME) had the same issue (somewhat) where it would only count up. If it’s not then flip the wire. A good troubleshooting technique to test if I did it right was to just spin the bot; not too fast but enough so that you would know that the values should count up or down (obviously while secured well).
