Serial communication about pixelcontroller HOT 10 CLOSED

well the ardunio uno has some issues with the serial latency, i never played with a nano. take a look at http://neophob.com/2011/04/serial-latency-teensy-vs-arduino/.

you can play with the serial timing in the firmware, but if you want the best result, use a teensy!

you can check out this project https://github.com/neophob/lpd6803-processing, compile it (ant) and insert the library into the pixelcontroller lib dir. you can increase the timeout for the ack message.

from pixelcontroller.

With serial timing in firmware, you mean;
#define SERIAL_WAIT_DELAY 3 ?

Thanks already,

exactly!

Ok, thanks.
What do you mean with "8ms is the minimum! else we dont get any data!"
The value is only 2. Should I try a lower value (1 or 0) ?

there is a 3ms delay, looped 3 times, so i suggest you increase the loop times (SERIAL_DELAY_LOOP)

Thanks for the help!
My teensy arrived, works flawlessly now.
Thanks for the amazing software.

Can I just ask how to configure two displays next to each other in the config file?
Can't seem to find an example of that.

from pixelcontroller.

take a look at the configuration.properties file, there you configure how many panels are used. what kind of panels do you use? how they are wired? how does your config file looks like?

cheers

Wel I'm using some LPD-6803 LED modules I had left from a different project.
I installed them 8*16. They're wired as if they were two different panels, just like those PixelInvaders panels.
In the config file, I have this
pixelinvaders.layout.row1=ROTATE_180_FLIPPEDY (guess I wired them differently)
but I don't know how to configure the next display, which is on the same row.

By the way, I realize I'm not supporting you by using your own panels, so I was wondering if I could donate something to the PixelController project?

Thanks already,

Daan

Hey Dan, take a look at the pixelcontroller example files (https://github.com/neophob/PixelController/blob/master/data/config.examples/PixelInvaders.cfg):

Two Panels Horizontal:
pixelinvaders.layout.row1=NO_ROTATE,NO_ROTATE

Two Panels Vertical:
pixelinvaders.layout.row1=NO_ROTATE
pixelinvaders.layout.row2=NO_ROTATE

you can ofcourse replace NO_ROTATE with other valid options.

and donations could be documentation, videos, images, like it on facebook (https://www.facebook.com/PixelInvaders), tell your friends or paypal ([email protected]).

cheers
