5fb67c666d v0.14. Rearrange DEBUG functionality, disable by default.
v0.14. Add ‘DEBUG_MENU’ which can be uncommented to enable the basic
debug menu with the ability to run a capture / dump the data etc.
DEBUG and DEBUG_MENU are commented out by default to save RAM.

9a065516e2 Add additional diagnostic commands.
You can connect via the serial monitor and send ‘?’ to get a list of
commands available.  This allows some diagnostics when the board isn’t
working with the OLS client.
Sending ‘4’ does a 4MHz capture and ‘2’ dumbs the data buffer for
example.  Recommended to use this with the simulated signal via a
timer.  See the bottom of the setup() function and change the ‘#if 0’
to ‘#if 1’ to enable it.
Also, fix a long standing bug that broke 2MHz captures and the
ATmega168. (improper #if defined check)

23fb253929 Fix sketch size for ATmega168
Automatically skip the inline2MHz sample rate on an ATmega168 based
Arduino.  4MHz will still work fine and the sketch will fit (10kB
instead of 16kB+)

Cleanup older notes from the README.  Move the part about disabling
auto-reset to towards the end under ‘older notes’ and add a comment
about how it shouldn’t be necessary.  Almost move the part about the
device profiles as they are builtin to ols-0.9.7 or newer.

9c83897b9b Correct preprocessor logic to avoid data gap on the Mega.
Fixes issue #14 where I copied the preprocessor logic from a different
Mega related check and didn't fix up the elif.  So samples from 512 -
1023 were always zero on the Mega.

d7c1bf52a8 Add 2MHz and 4MHz sample rate support.
Use unrolled loops to sample at 2MHz & 4MHz rates.  Based on some
testing by Bob Davis (http://bobdavis321.blogspot.com)
The maximum with a 16MHz clock is 5.3333MHz (3 cycles per sample) but
sampling at that rate isn't very accurate.  Accuracy is pretty good at
2MHz & 4MHz.

8c7db04e3c Increase portdelay so that Arduino Uno R3 works.
For some reason the Arduino Uno R3 (but not my earlier / original Uno)
needs a longer delay after reset.  I haven't investigated the cause
yet, but increasing device.open.portdelay to > 1700ms seems to fix it.
Bump to 2000 just to be safe in all cases.  This should fix the Uno R3
issues that have been reported a couple of times now.

Triggers are more reliable on PORTB.  I am working on fixing triggers
on PORTD, but I'm setting this back to original behavior (with a
#define USE_PORTD available) so this isn't broken for triggering.

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.

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.

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.

@@ -5,26 +5,29 @@ This Arduino sketch implements a SUMP protocol compatible with the standard
SUMP client as well as the alternative client from here:
http://www.lxtreme.nl/ols/
The alternative client version is highly recommended. Download version
"ols-0.9.7" or newer for built-in device profiles.
This SUMP protocol compatible logic analyzer for the Arduino board supports
5 channels consisting of digital pins 8-12, which are the first 5 bits (0-4)
of PORTB. Arduino pin 13 / bit 5 is the Arduino LED, bits 6 & 7 are the
crystal oscillator pins.
Uncomment CHAN5 below if you want to use the LED pin as an input and have
6 channels.
NOTE:
You must DISABLE the Arduino auto reset feature to use this logic analyzer
code. There are various methods to do this, some boards have a jumper,
others require you to cut a trace. You may also install a *precisely*
120 Ohm resistor between the reset & 5V piins. Make sure it is really
120 Ohm or you may damage your board.
On the Arduino Mega board 8 channels are supported and 7k of samples.
Pins 22-29 (Port A) are used by default.
To use this with the original or alternative SUMP clients,
use these settings:
Sampling rate: 1MHz (or lower)
Sampling rate: 4MHz (or lower) (no 2MHz on ATmega168)
Channel Groups: 0 (zero) only

Debugging
=========
You can uncomment the '#define DEBUG_MENU' line to add some diagnostic menu
options for capturing or dumping the capture buffer.
You can uncomment the '#define DEBUG' and '#define DEBUG_MENU' for a couple
extra menu options and logging of the received commands. The DEBUG option
is generally only useful for development, while the DEBUG_MENU option is
good for troubleshooting when the logic_analyzer sketch isn't working for you.
Both are disabled by default to conserve RAM for improved stability.
Older Notes
===========================================================================
NOTE: With v0.11 you can now sample at 4MHz & 2MHz rates in addition to the
previous 1MHz and lower rates. This is done via unrolled loops which
makes the source code huge and the binary takes much more of the flash.
v0.11 is just slightly to big for an ATmega168's flash. You can comment
out either captureInline2mhz() or captureInline4mhz() and it will fit.
[ The code automatically skips the 2MHz code now, this isn't needed. ]
NOTE: v0.09 switched the channels BACK to pins 8-13 for trigger reliability.
Please report any issues. Uncomment USE_PORTD for pins 2-7.
NOTE: The device profiles should be included with this code. Copy them to the
'plugins' directory of the client. The location varies depending on the
platform, but on the mac it is here by default:
/Applications/LogicSniffer.app/Contents/Resources/Java/plugins
[ These are included in ols-0.9.7 or newer so do not copy them. ]
NOTE: If you are using the original SUMP client, then you will get a
"device not found" error.
You must DISABLE the Arduino auto reset feature to use this logic analyzer
code. There are various methods to do this, some boards have a jumper,
others require you to cut a trace. You may also install a *precisely*
120 Ohm resistor between the reset & 5V piins. Make sure it is really
120 Ohm or you may damage your board. It is much easier to use the
alternative SUMP client referenced above.
[ This is not needed with ols-0.9.7 or newer. ]
[ DO NOT use this resistor unless absolutely necessary on old clients. ]
NOTE: This master branch now supports Arduino 1.0 only.
