SUMP client as well as the alternative client from here:

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.

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.

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,
|
||||

|
||||
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.

||||
Checkout branch logic_analyzer_v0_5 for Arduino 22 support.
