Changing device ID returning errors

Old Google Group Archive
#1

Hi All,

I was wondering if you could help me with an issue I am having while trying to use multiple all pixels together as a strip.

The first problem I am running into seems that bibliopixel cannot find the devices listed in the script (for example driver A being device 0 and driver B being device 1)

This I imagine is because they all come with a device ID of 0 out of the box and it runs into problems when there is more than one device with the same id.

When I try changing the device id using " Bp Devices" or “bibliopixel devices” or “bp -v devices” it keeps returning this error: “Programmer error with exception can’t concat int to bytearray”

Ive attached the script we are trying to run and a picture of the outcome aswell.

Any Ideas of what might be happening as we kind of ran into a wall here?

Thanks!!

Okay so just realised the new release of bibliopixel came out and that fixed the device id changing problem however we still are having a problem running the previously attached script. It is now returning the error attached.

Just to add we are able to connect them and run them separately using a modified code of the original posted one. attaching it here

Update: we managed to force it to connect by defining the com ports it needs to connect to before looking for the id and trying to find the com automatically. We added for example dev=com9

Interesting… that will definitely help debug. But unfortunately Windows doesn’t always give the same device the same COM port number after reboot… which is why the ID system exists.
I’ll see what I can find tonight.

Ok… bad news. It’s a bad bad bug that we missed. And it’s been broken for quite a while -> https://github.com/ManiacalLabs/BiblioPixel/issues/1126

Which mostly means that you are the first to use that feature in nearly 2 years.

Honestly, all I can suggest at the moment is to use BiblioPixel v2 -> https://github.com/ManiacalLabs/BiblioPixel2
At least until the issue is patched.

Alfred, I’d need to see the actual animation code you are running. Some animations just don’t run quickly. I might be able to give you some tips to optimize your code.

Ah, sorry, I didn’t see that this was addressed just to me!

First, we have a fix for the original issue.

Unfortunately, we got held up on pushing that fix because of an unrelated problem in the continuous integration system that :-/ almost certainly we didn’t cause. https://github.com/ManiacalLabs/BiblioPixel/issues/1130

But we’ll get this in today, if we have to ignore the bogus warnings from the system to do so!

As for the framerates - not entirely sure what’s going on there! Adam?

Thank you for the support. So far were getting by with defining the ports manually on windows. Using the pi it finds them automatically. The issue were running into at the moment is that we are trying to run 2494 leds using 4 all pixels and were getting low framrates (9fps). When running half of it using 2 all pixels its at around 20fps but when we add the other 2 drivers with around 600 leds on each it drops. When using 4 drivers to run only half the leds it still remains at 20fps when it should have ran at sround 40. On the pi we get around 4 fps and when we use threaded update the prompt prints that its acheiving around 18fps but it doesnt output properly to the matrix but on the pc it seems to work at 30 fps using threaded update. While trying to use anim.run on a new thread the join thread variable cannot be found and setting threaded to true seems to run the script and then exits. Any idea what we could do to increase the framerate?

Thanks and regards

The fix probably isn’t so terrible - we can likely get it out pretty fast.

Ok… bad news. It’s a bad bad bug that we missed. And it’s been broken for quite a while -> https://github.com/ManiacalLabs/BiblioPixel/issues/1126

Which mostly means that you are the first to use that feature in nearly 2 years.

Honestly, all I can suggest at the moment is to use BiblioPixel v2 -> https://github.com/ManiacalLabs/BiblioPixel2
At least until the issue is patched.

I’ve not been able to reproduce it yet on my end. Still working on it and will try a couple more things this evening.

Is there any fix on the com port issue?

Interesting… that will definitely help debug. But unfortunately Windows doesn’t always give the same device the same COM port number after reboot… which is why the ID system exists.
I’ll see what I can find tonight.

Update: we managed to force it to connect by defining the com ports it needs to connect to before looking for the id and trying to find the com automatically. We added for example dev=com9

Will take a look tonight when I’m back at said Windows machine :slight_smile:

Hmm, you do seem to be getting some sort of legit communications error with the new code… but unfortunately I personally don’t have a Windows machine to test it on to reproduce the issue.

BP does support multiple devices and it should go much as you are indicating.

Adam will be on later and has the ability to test multiple devices on Windows, so let’s see what he says!

Just to add we are able to connect them and run them separately using a modified code of the original posted one. attaching it here

Okay so just realised the new release of bibliopixel came out and that fixed the device id changing problem however we still are having a problem running the previously attached script. It is now returning the error attached.

Hi All,

I was wondering if you could help me with an issue I am having while trying to use multiple all pixels together as a strip.

The first problem I am running into seems that bibliopixel cannot find the devices listed in the script (for example driver A being device 0 and driver B being device 1)

This I imagine is because they all come with a device ID of 0 out of the box and it runs into problems when there is more than one device with the same id.

When I try changing the device id using " Bp Devices" or “bibliopixel devices” or “bp -v devices” it keeps returning this error: “Programmer error with exception can’t concat int to bytearray”

Ive attached the script we are trying to run and a picture of the outcome aswell.

Any Ideas of what might be happening as we kind of ran into a wall here?

Thanks!!
