Exclamation Re: Unresponsive camera

We're having the same problem as you...

but following the procedures of the document .pdf for testing the TTL 232, we evidenced that the TTL port and the TTL 232 don't have any problem. But, when we reloaded the default code 2.4, the camera continues to not be found. Maybe the problem is not the TTL

We're really confused right here

Re: Unresponsive camera

We have conducted the prescribed test as well and found that the TTL-232 board was working.

Yet we continued to find that we had the camera not found problem.

We also discovered a few other things:

The trigger on the joystick attached to port 2 was not functioning. This explains why on occasion it would NOT give us the “camera not found error” but the lights on the OI to indicate which color to track would not change.

Currently, the camera is working with the robot on the bench in the workshop area.

However, I still don’t know why it is working.

When we started testing on the bench it was NOT working.

We retested every thing again including the TTL-232 board. All ok, still it didn’t work.

Then it did work.

The current hypothesis is that it is a problem in the connectivity. Each end is just fine but the connection is tenuous in between. It could be a loose connection or it could be RF interference with the power system based on the routing of the signal wire to the power distribution system.

It is frustrating because its working and I don’t know why!

Re: Unresponsive camera

INCREDIBLE!!!


Here, in a desperated act, we turned the camera on the 2004 RC (It haves a TTL port), by updating the firmware and downloading the 2.4 code. It works.

So we tried to do everything by the beginning with the 2005 RC, downloading the 2.4 code clean on the IFI webpage, updating the firmware again, and then.... TADA!! THE CAMERA NOW IS WORKING!! Our team is very happy now.

I think that do everything by the beginning can help the teams with this problem.
