Add support for Arduino Mega external SRAM.

Using external SRAM (like Rugged Circuits "QuadRAM" board) we can have
up to 55KB of capture buffer space.

+SUMP compatible logic analyzer for Arduino
+==========================================
+
+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/
+
+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.
+
+On the Arduino Mega board 8 channels are supported and 7k of samples.
+Pins 22-29 (Port A) are used by default, you can change the 'CHANPIN' below
+if something else works better for you.
+
+NOTE:
+If you are using the original SUMP client, or using the alternative client
+without the device profiles, 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.
+
+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
+
+To use this with the original or alternative SUMP clients,
+use these settings:
+
+Sampling rate: 1MHz (or lower)
+Channel Groups: 0 (zero) only
+Recording Size:
+   ATmega168:  532 (or lower)
+   ATmega328:  1024 (or lower)
+   ATmega2560: 7168 (or lower)
+Noise Filter: doesn't matter
+RLE: disabled (unchecked)
+
+Triggering is still a work in progress, but generally works for samples
+below 1MHz.  1MHz works for a basic busy wait trigger that doesn't store
+until after the trigger fires.
+Please try it out and report back.
+
+This master branch now supports Arduino 1.0 only.
+Checkout branch logic_analyzer_v0_5 for Arduino 22 support.
+
+Release: v0.06 November 4, 2011.

-SUMP compatible logic analyzer for Arduino
-==========================================
-
-This Arduino sketch implements a SUMP protocol compatible logic analyzer.
-This implementation is compatible with the standard SUMP client as well as
-an alternative OLS client.  More recently support has been added to Sigrok.
-
-This logic analyzer for Arduino supports 6 channels consisting of digital
-pins 8-13, which are the first 6 bits (0-5) of PORTB.
-Arduino pin 13 / bit 5 is the Arduino LED, bits 6 & 7 are the crystal
-oscillator pins. Comment out CHAN5 if you don't want to use the
-LED pin for an input.
-
-On the Arduino Mega board 8 channels are supported and 7k of samples.
-Pins 22-29 (Port A) are used by default.
-
-Installation
-============
-
-You can use the GitHub 'Download ZIP' feature to get an installable "library"
-for use with the Arduino IDE.  Select 'Sketch -> Include Library -> Add .ZIP Libary'
-from the Arduino IDE 2.x and select the zip file you downloaded from GitHub, then select open.
-
-Once installed you can use the 'File -> Examples -> LogicAnalyzer' menu to find
-different versions of the sketches.  You might want to start with `logic_analyzer_sigrok`
-and use PulseView.
-
-Client Software
-===============
-
-Sigrok support via the 'ols' device configuration has been added. This
-mostly involved returning the capture buffer in the reverse order.
-
-Use the `logic_analyzer_sigrok` sketch.  Since the OLS alternative client
-mentioned below has some issues with newer Java versions, Sigrok is currently
-the only practical way to use this logic analyzer.  If you use an older machine
-with an older operating system and older Java you can probably use the OLS client.
-
-Sigrok support seems to work fairly well so I would currently recommend it for
-anyone interested in trying this sketch.
-
-Run PulseView like this on Linux: (I'll add Windows options after more testing)
-```
-PulseView --driver=ols:conn=/dev/ttyUSB0 --dont-scan
-```
-
-It may be necessary to exit and relaunch PulseView to get it to recognize the device.
-An easy way to test the device is using the `sigrok-cli` utility. The command below
-samples channel 2 at 1MHz.  If you get a device not found error, but /dev/ttyUSB0 exists,
-run this command a couple times and usually it will start working. Due to the way opening
-the serial port resets the Arduino there are some issues/bugs to work out yet.
-```
-sigrok-cli --driver=ols:conn=/dev/ttyUSB0 --config samplerate=1Mhz --config pattern=External --samples 1024 --channels 2
-```
-
-The OLS alternative client hasn't had an official release recently so you will
-need to compile it yourself.
-
-Follow the build instructions here: https://github.com/jawi/ols
-
-
-Older details on the OLS client is available at the project page:
-https://lxtreme.nl/projects/ols/
-
-Direct link to older releases of the OLS alternative client:
-http://www.lxtreme.nl/ols/
-
-The alternative client version is highly recommended.  You can tried the older
-release ols-0.9.7.2 but most likely need to build it yourself. Use "ols-0.9.7"
-or newer for built-in device profiles.
-
-To use this with the original or alternative SUMP clients,
-use these settings:
-```
-Sampling rate: 4MHz (or lower) (no 2MHz on ATmega168)
-Channel Groups: 0 (zero) only
-Recording Size:
-   ATmega168:  532 (or lower)
-   ATmega328:  1024 (or lower)
-   ATmega2560: 7168 (or lower)
-Noise Filter: doesn't matter
-RLE: disabled (unchecked)
-```
-
-Using the Logic Analyzer
-========================
-Triggering is still a work in progress, but generally works for samples
-below 1MHz.  1MHz works for a basic busy wait trigger that doesn't store
-until after the trigger fires.
-
-Please try it out and report back.  Please provide a detailed bug report
-if you file an issue.
-
-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.
-
-CLI compiling
-=============
-
-If you want to use the `arduino-cli` tool to compile this using the Makefile,
-you'll need to install the tool first following instructions here:
-https://arduino.github.io/arduino-cli/
-
-Once installed you can simple type `make` and you should get some simple help:
-```bash
-$ make
----> run 'make build' to compile for Arduino Duemilanove
----> run 'make upload' to upload to /dev/ttyUSB*
-```
-
-
-Other Notes
-===========================================================================
-```
-NOTE: Starting with v0.11 you can 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 too big for an ATmega168's flash. The code 
-      automatically skips the 2MHz code on ATmega168
-
-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: 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. ]
