51df725ee8 Add notes about 2MHz/4MHz mode and binary size.
Also move a couple more things under #ifdef DEBUG in an attempt to
reduce the code size for ATmega168.
It current doesn't fit in the '168 but maybe after some more tweaks.

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.

69de405dd5 Release v0.10 with a fix for the Arduino Uno R3.
The only change is an updated ols.profile-agla.cfg that works with the
Arduino Uno R3.

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.

0a40fdb2ac Update comment to reflect that PORTD seems to work, but needs testing.
I'm still working on PORTD triggers.  I'm not yet satisfied they are
working 100% correctly.

1f7eb0aecd Add missing shift for PORTD trigger. 2013-06-22 11:30:39 -07:00
Andrew Gillham
dc3d85abf7 Revert to PORTB (Arduino pins 8-13) and make PORTD a configuration option.
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.

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.

SUMP compatible logic analyzer for Arduino
==========================================
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.
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.
