Post EV3 Reliability Issuses with non-LEGO Sensors
Hi All,

I'm having lots of EV3 reliability issues with non-LEGO Sensors. Code runs initially then the next time the EV3 Hangs and needs the batteries removed to recover, or the EV3 enters an Error state, but needs a full power down to recover.

Is anyone else having similar issues?

Can you be more specific about the actual sensors you're having issues with? Sometimes, simply yanking the sensor out and reconnecting it, will do the trick.

Besides the HT Colour Sensor causing headaces, the sensors that causes the biggest collection of hangups is the EV3 "Anyway" Segway using the CruizCore XG1300L Sensor.

It seems to work correctly without sending the EV3 off-the-rails, about 1 in 5 goes. If I try to use a NXT Sonar Sensor with it as well, it behaves probably 1 in 10 times.

I failed to get the EV3 "Anyway" Code to compile with the HT Gyro, and gave up chasing errors in the "segway-driver-lv.h".

I can't remember whether I tried the Dexter IMU with the EV3 or not now. If I have a few spare minutes tomorrow I will give it a try and see what happens.

I have also notice that with my old NXT based "Anyway", using the Dexter IMU, that I introduce instability issues when I compile the code in RobotC 4.30. Compiling the same code with RobotC 3.62, and all is happy. I think the Firmware 1030 may be the cause.

I also forgot to mention that when using the "Debug Stream" in RobotC 4.30, when a Sensors causes a failure failure on the EV3 Brick, the RobotC Program automatically shuts down on my Windows7 machines.

Sometimes RobotC 4.30 just freezes the Program itself and the mouse. This requires me to shut it down with Task Manager via the Keyboard. Other times I gain control after a good minute or so.
