Error code in maestro

Support Servo controllers and servos
1

I have a Pololu Maestro 18 channel that I am using for a droid project. I had this working perfectly till my Arduino bit the farm. since then I have gotten a new Arduino with a USB host shield that works with the Bluetooth controller. problem is that I cannot get one of the maestro’s to come back to life on the controllers. I am using an Arduino mega2560 to call up the programs on the maestro. every time I do now I get an error code. thing is I only get it in one of the two maestro’s in the system though both are separate and called up differently in the Arduino program. I am going to post both of the codes one for the body maestro and the other for the head. it is the head one that is not currently working.

Hello.

When it gets into an error state (indicated by the red LED), could you connect the Maestro to your computer and check which error being triggered? Could you post the settings files for each of your Maestros (being careful to indicate which one belongs to each Maestro) as well as the simplest possible Arduino code that demonstrates the problem?

By the way, I noticed that in both of your scripts all of the subroutines end with a return statement. So, if you are using the “Restart Script at Subroutine” command to call any of them, I expect that to end in an error (since the Maestro has nowhere to return to). If you want it to play that sequence once and stop, the subroutines you call from your script should end with a quit command.

That might be my problem I forgot about the quit command between programming. I will check that and see if it might help.

Well it turned out the maestro is dead. I put a new one in with the same programming and it worked right out of the gate but the previous one did not so I am assuming it is dead.

I’m sorry to hear about your Maestro, but I’m glad you were able to get your system working. If you haven’t done so already, you might try saving the settings file from your working Maestro and loading it onto your problematic Maestro, just in case there was something else in the settings that was causing the problem. (You can save or load a Maestro settings file from the “File” drop-down menu of the Maestro Control Center while the controller is connected.)
