--------------------------------------------------------------------------------

2010-12 jcw

* Added new RF12_WANTS_ACK and RF12_ACK_REPLY macros.

* Check that ACK is indeed intended for this room node (thx bgreene).

* Condensed this change log into monthy sections.

2010-10 jcw

* Fix bug when roomnode didn't receive ack: http://talk.jeelabs.net/topic/622

* Added glcdNode.pde sketch.

* Added call to Sleepy::watchdogEvent().

* Started work on new roomNode.pde sketch.

* Added rgbRemote.pde sample sketch.

2010-09 jcw

* Added packetBuf.pde sample sketch for sending strings around.

* Added promiscuous mode to the RF12 driver, by specifying net group 0.

* Added rf12_sendStart(hdr) call option, to support buffer-less sending.

* Added rf12_sendWait(mode) as separate call, replacing the "sync" parameter.

* Increased rf12_buf size, header offsets changed (use rf12_len, etc).

* Added rf12_grp #define, to access and set the actual net group.

* RF12demo sketch to support promiscuous mode (reports "OKG" and "?G").

* Added "1q" command to disable reporting bad packets, i.e. no more "?...".

* Added #define FLASH_4MBIT code to recognize new 4 Mbit flash chip on JeeLink.

2010-08 jcw

* Moved generic low-power code to a new "Sleepy" class in the Ports library.

* Reduce power use when rf12_sendStart() called in sync mode.

* Added new "radioBlip.pde" demo for low-power testing.

* Fixed RF12demo to reply with a broadcast ACK if a packet was addressed 

  specifically to them requesting an ack (the previous code ignored it).

2010-07 jcw

* Added #ifdef's to use the RF12 library with the Arduino Mega (thx bartvb).

2010-06 jcw

* Avoid digitalWrite() for chip select, use direct pin I/O for speed.

* Add sync mode option to rf12_sendStart(), waits until packet has been sent.

* Added new rf12_control() function for low-level register access.

* Fix nodeid 10 being reported as 0 (!) - see http://talk.jeelabs.net/topic/378

* Clarified use of "cmd" var in RF12demo with the use of an extra var.

* Fix transmission rate comment in RF12, it's approx 49 Kbps, not 57.

2020-05 jcw

* Added pingPong.pde example sketch to explain an issue with rf12_canSend().

* Fixed a bug with OOK sending, introduced by the 2010-04-09 "fix".

* Avoid lockup on the dataflash test in RF12demo.

2010-04 jcw

* Fixed RF12demo to send broadcast ack back on fully addressed requests.

* Fixed power-up reset problem in RF12, wait until RFM12B is fully inited.

* Tweaked contents of this file to be compatible with Markdown formatting.

* Fixed RF12demo to support sending out ACK packets via the 's' command.

* Solved! Initial SPI transfer had to be added to avoid problem after power-up.

  See http://talk.jeelabs.net/topic/169 for the discussion that led to solution.

2010-03 jcw

* Added DATAFLASH #define to build RF12demo with or without DF detect code.

2010-02 jcw

* RF12 patches to clean up the code, many thx to Marius Kintel.

* Fixed argument order on command line for FS20 and KAKU commands in RF12demo.

* Changed greeting to [RF12demo] i.s.o. [RF12DEMO].

2010-01 jcw

* Added support for low-battery detection, threshold set to 3.1V.

* Added RSSI listen-before-send carrier detection.

2009-12 jcw

* Same timing changes applied to KAKU, code streamlined a bit more.

* Improved FS20 timing with RFM12B in OOK mode (thx JGJ Veken).

* Updated README to match new RF12demo commands and syntax.

* Fix the "rf12_easySend(0,0)" special case, so it resends a full packet.

* Added new rf12_easyInit(), rf12_easyPoll(), and rf12_easySend() functions.

2009-11 jcw

* Fixed problem when handling an aborted replay and add "DF E" at end of replay.

* Added "DF R" output (and fixed it). To be flashed into ATmega's from now on.

* Several fixes to new RF12demo code, added replay and ack-suppress code.

* Started implementing support for the JeeLink v2's flash memory.

2009-10 jcw

* Added FS20/KAKU remote control cmds to RF12demo and activity LED on/off.

* Added <Ports.h> includes to all the examples, due to new dependency :(

* Detach interrupt in OOK mode to allow switching between OOK and FSK modes.

* MilliTimer is now in the Ports library, so it has been removed from RF12sio.

2009-06 jcw

* Made v2 protocol the default, i.e. crc includes group. Incompatible with v1!

* Cleanups, remove some recent new ack code which won't be used after all.

2009-05 jcw

* Added new rf12_recvAcked() code to take care of ack-sending as 0-byte reply.

* Added new rf12_sleep() to manage RF12 power-down, with optional wakeup period.

* Added first basic version of the new streaming I/O layer as "RF12sio.{h,c}".

* Added rf12serial and rf12stream demo sketches to the RF12 library.

* Changed the default group to 0xD4, other values only supported by RFM12B's.

* Extended the RF12demo into a general RF12 EEPROM configuration utility.

* Added rf12_config() to initialize the RF12 hardware from settings in EEPROM.

* Added $Id comment lines to all source files so filenames are shown in files.

2009-04 jcw

* Added support for v2 protocol, with group added to crc and default group 0x51.

* Removed rf12_group(), it's now an optional arg of rf12_initialize() instead.

2009-03 jcw

* Added README to "RF12demo" sketch with instructions on how to run some tests.

* Added rf12_group() to allow changing the group from 0x50 to something else.

* Extended RF12demo to also configure frequency band, not just the node id.

2009-02 jcw

* Regression fixed, failed to set up ack sending with proper source node id.

* Changed rf12_initialize() args to node ID plus one of 3 frequency band codes.

* Added rf12_onOff() for OOK emulation (must initialize with node ID zero).

* Added new "fs20demo" example to control FS20 devices from the RFM12B.

* Added new "kaku_demo" example to control KlikAanKlikUit devices at 433 MHz.

* Replace EEPROM.h in "RF12.cpp" with eeprom_*() calls in "RF12demo.pde".

* Subversion repository moved to Google code.

* Comments added to RF12.h to describe each public function.

* Made rf12_recvStart() private, this is handled by rf12_recvDone().

* Replace ISR(INT0_vect) by call to attachInterrupt() to avoid duplicate

  definition error. Code now also works with Arduino-0013.

2009-02-09 jcw

* Public release.
