This change log is no longer maintained as a separate file. You can now browse all the source code and see all the changes and comments ever made on the web. The home page for this library, including its automatic change log, is: http://jeelabs.net/projects/cafe/repository/show/RF12 To check out the latest version, use subversion: svn co svn://svn.jeelabs.org/jeelabs/trunk/libraries/RF12 For more information about subversion and source code from JeeLabs, see: http://jeelabs.org/2010/12/15/subversion/ -------------------------------------------------------------------------------- 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 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.
