240ebc134c Update to v0.08 and add note about channels changes. 2013-02-08 17:06:23 -08:00
Andrew Gillham
396a3ccfa5 Switch to 6 channels on PORTD.
Switch from PORTB to PORTD so that a full 6 channels can be used
without messing with the LED.  Per suggestion in issue #7.  I was
unable to find any issues with using PORTB.  During initial development
I ran into some noise & stability issues but I believe those were
solved later via allowing the ports to settle prior to beginning
sampling.
This allows for 6 channels, starting with digital pin 2 (next to the
UART TX pin) and ending at digital pin 7.
The debug pin is now digital pin 8.

864ae2c826 Implement RLE mode for 50Hz or lower sample rates. (via hhermsen in issue #9)
Support RLE mode for samples rates of 50Hz or less.  Code from hhermsen
in issue #9.
This is a work in progress.  Hopefully RLE can be added for higher
sample rates in the future.

851b7e0735 Add firmware version to metadata
Return the firmware version to the Logic Sniffer extended SUMP protocol
metadata request.  Now you can see what version is loaded on your
device.

b1a43e57c7 Update device profile clockspeed.
The Mega also runs as 16MHz so update device.clockspeed to match.

1f418098b2 Update device profile clockspeed & portdelay.
Set clock speed to 16MHz.  Hopefully this value works fine with the
client since the previous 100MHz was not the actual clockspeed anyway.
Also, adjust the device.open.portdelay to 1500ms.  People can test
their own device for the fastest value, but this should be a safer
default for most people and hopefully eliminates som frustration for
first time users.

LogicSniffer client application.

f51d0bbb96 Improve pre-trigger sampling on below 500kHz sample rates.
The sample loop was not padded properly in the loop waiting for the
trigger to fire. As a result it was sampling at a much higher rate than
the post trigger sample rate.  I've added some delays and padded it out
a bit, it needs further measurement, but is usable now.

3a6329775c Merge pull request #3 from scottp/master
Correct long standing bug in the device profiles on github where the data was being reversed by the client due to the reverseOrder setting.  The sketch returns the data in the sampled order, but the client appears to expect it reversed, so the sense of the setting is backwards. Data is in the correct order based on a simple test program, even though the setting is "wrong".  Invert the comment as well.  Also increase the delay on the Mega as it doesn't always respond fast enough. Patches from scottp.

3c69ec10a1 ols.profile-*: Reverse IO order received in config
Fixed reverseOrder and comments

As per this post:
http://dangerousprototypes.com/forum/viewtopic.php?f=57&t=2432

The comment talking about device.samples.reverseOrder is reversed. I have
fixed the order and the comment and tested.

7173e83e14 ols.profile-aglam.cfg: Increased delay time
On testing a number of Arduino Mega boards, I found the device missing error.
Now it seems to be always working if you set it to 2000.
