Rainbowduino v3.0b freezes after a few seconds

[devinejohnny]

First, awesome work. I love what your doing with light and sound and I love even more that you are putting it out here for the public to enjoy.

I see in the other issues here that you are working on getting the v3.0b Rainbowduino to jive with the Pixelcontroller, so this may be what you are currently working on, but I thought I'd throw it out any way.

I've been able to use Pixelcontroller to light up my homemade LED matrix (64 RGB LEDs) via the Rainbowduino v3.0b for about 5 to 10 seconds, at which point it freezes. The RX light on the board continues to flash red, but the image on the matrix does not change.

I've had the same results when I run the program from my Mac and from my PC.

I made the changes to the wire.h and twi.h files (increased frequency to 400 kHz, and buffer size to 98).

Again, if this is the same issue you are already working on with the RainbowduinoV3, feel free to ignore this post, but if you see something simple that I'm doing, I'd love to hear what it is! I feel like I'm so close to having this awesomness up and running!

Here is the log from the last time I ran Pixelcontroller:

Hmm well PixelController already works with the Rainbowduino v3. However it looks like your Rainbowduino board is crashing.

Can you replace the board to make sure its not a HW issue?

While you was editing the wire and twi files, you Arduino IDE was closed?

What Arduino version do you use?

Try to replace the USB cable (maybe with a shorter one)

What happens if you don't power up your DIY LED Matrix (only the Rainbowduino board)?

[devinejohnny]

Thanks for the response and suggestions.

I have another v3.0b board, so I swapped it out and tried again. The result was the same.

When I edited the .h files Arduino IDE was closed. I just checked both files to make sure the changes were in place, then relaunched the IDE, uploaded the firmware, and opened PixelController. The issue is still present.

I'm using Arduino 1.0.5 on both my Mac and PC.

I unplugged my matrix from the Rainbowduino and launched PixelController. The issue is still present (both the TX and RX lights on the Rainbowduino will flash for a couple seconds, then the TX turns off, but the RX continues to blink).

The last thing for me to try is the new cable. I'm using a 3 foot cable right now, but I'll go buy some other options and report back.

Thanks for the help so far!

[devinejohnny]

I've tried two new cables (thicker 6 foot cable and a different 3 foot cable) on both Rainbowduinos with the same result.

I uninstalled my Arduino IDE and re-downloaded it. I made the changes to wire.h and twi.h files before launching it. I reloaded the firmware on my Rainbowduino, but am still getting the crash.

Am I using the correct firmware:

/* Rainbowduino V3 firmware capable of streaming 24bit RGB frames with up to 35fps via the USB connector of the Rainbowduino V3 controller.

Author: Markus Lang (m@rkus-lang.de) Websites: http://programmers-pain.de/ https://code.google.com/p/rainbowduino-v3-streaming-firmware/

This firmware is based on several Rainbowduino related firmwares like: neorainbowduino: http://code.google.com/p/neorainbowduino/ rainbowdash: http://code.google.com/p/rainbowdash/ seeedstudio.com: http://www.seeedstudio.com/wiki/Rainbowduino_v3.0

The Java part splits a full 8x8 RGB frame (3 colors * 64 LEDs = 192byte) into four frame fragments (each 48byte) to get around the 64byte default buffer size of the Arduino hardware serial implementation. Each fragment will be extended with the HEADER bits and a frame fragment index to be able to reconstruct the full frame in the correct order inside this firmware.

Splitting up the frame into fragments avoids running into data corruption / data loss if the Java part sends more bytes than the Arduino controller can buffer. For every frame fragment the controller will send an ACK REPLY message to the Java code so that the next fragment will be send.

The firmware is able to handle incomplete frames as well as CRC checksum errors of the transferred LED color data so that it's able to signal those error conditions to the Java API.

The LED update routine of this firmware is just a rewrite of the original seeedstudio.com firmware (http://www.seeedstudio.com/wiki/Rainbowduino_v3.0) including some changes regarding the interrupt handling to allow the controller to update the LEDs and receiving incoming serial data at the same time. */

I don't think there is a hardware issue. I bought the boards from different outlets (one from California, the other from Hong Kong) and they are both able to run my DIY LED matrix using the RainbowStudio and the example sketches from SeeedStudio.

pixelinvaders.blacklist.devices=/dev/ttyUSB000

if you have multiple pixelinvaders panels wired up special, you can define this here.

if you don't define this setting, the "default wiring" is expected

example (the number define the wiring direction):

+---+---+---+

| 0 | 3 | 4 |

+---+---+---+

| 1 | 2 | 5 |

+---+---+---+

HINT: the first panel is 0!

pixelinvaders.panel.order=0,3,4,1,2,5

pixelinvaders.panel.ip=192.168.111.22

pixelinvaders.panel.port=5333

=========================

serial device names + layout definition

on Linux/OSX use names like "/dev/ttyUSB1"

on Windows use names like "COM1"

This is for one of my boards:

layout.row1.serial.devices=/dev/tty.usbserial-AD01W4YR

This is for my other board:

layout.row1.serial.devices=/dev/tty.usbserial-A901LS8Z

layout.row2.serial.devices=/dev/ttyUSB2,/dev/ttyUSB3

settings for Art-Net, Null output, Minidmx, UDP, TPM2 and Adavision

=========================

output.resolution.x=8

output.resolution.y=8

flip each second scanline

output.snake.cabling=true

OR use manual image mapping, instead of the snake cabling setting.

the output mapping table should contain output.resolution.x * output.resolution.y entries

REMEMBER: the first outputs starts at 0 NOT 1!

output.mapping=0,1,4,5,2,3...

optional rotate image, valid options:

NO_ROTATE (default),

ROTATE_90,

ROTATE_90_FLIPPEDY,

ROTATE_180,

ROTATE_180_FLIPPEDY,

ROTATE_270

output.layout=NO_ROTATE

=========================

settings for Art-Net

Info: PixelController supports more than 1 universe

do NOT FORGET to define the output resolution above!

=========================

artnet.ip=192.168.1.2

define how many rgb pixels are used on a universe, maximal 170 (=510 Channels)

artnet.pixels.per.universe=170

define the first universe id

artnet.first.universe.id=1

=========================

Ok! Sorry about that blast of info. I think I have it working stably now.

In the firmware I changed this line: const unsigned char ACK_REPLY_LENGTH = 10;

The variable was set to 4 and I increased it to 6. That allowed it to work a little longer before crashing, but now that I've put it up to 10, my Rainbowduino seems to be running just fine.

Awesome! Thanks again for this great piece of software and extra thanks for sharing it with the world.

ok glad it works. Hint: you may increase that value to 60, as thats the usb buffer size.
