is there a physical check to see if the Z sensor works ....I know the X-Y works .....It moves the elevator up and down when tilting the model ....Couldn't get the same reaction from the Z sensor ....
I don't know how many more computers I can try this on.... I am running out ;-)
I would like to see a video, not because I don't belive you but because I want to see how it reacts compared to mine. Please video from the beginning each step you do from power off to uploaded code showing your LED behaviour so we can compare. We are not the only ones having this problem, we are just the only ones working on it.
Hi Thomas, if the bootloader is diferent and programmed to pull down the pin d7 the shield will not work properly, is a fact. But is improbable that SF may changed the bootloader. Unless they burn the wrong loader, if that happens you will be unable to use it anyway. So I don't think so. I do believe that the problem is between the computer and the IDE. Because if you see the LEDs shutting off is because the shield is working.
Just o clarify the pin d7 must high in order to shoot it off and LOW to turn it on. When arduino enters in programing mode it always pull the pin d7 high (shutdown the gps), after the upload is complate it continues and pull down the pin d7 and the gps is power on again. I use it every day. Somebody would like see a video? Now maybe the bootloader is diferent and the version you have is not pulling up the pins.
Somebody with this problem that lives in South California? Would be nice have access to a problematic hardware.
Jordi, I'm not sure whether it is the board or not. If you look at the measurements I took and documented in the Ardupilot forum, when the GPS is connected, it seems D7 will not stay high while uploading, causing a uart conflict. Also, during the brief period D7 is high, the transistor collector is 1.5v, somewhat higher than the expected less than 1v. This seems to be enough to keep the 3.3v led lit.
