IC8.hex - MiniBOX (Simple LocoNet Command Station) main logic
IC4.hex - DCC Generator


CHANGELOG
---------
Version 1.8 - Supporting FREDI v1.9 F9-F12 using OPC 0xA3

Version 1.7-3-g8fedf6d 2017/12/4 (PIC16F648A only)
 New:
  - Supports LocoNet FAST CLOCK SLOT
  - Supports LocoNet PROG SLOT (OPS mode only)
  - Supports LocoNet SEND IMM PACKET 
  - Supports functions above F8 (using IMM PACKETS)

Version 1.6.1 Revision 1.86.1  2017/11/13
 bugfix: Fixed all time existing bug in keyboard scan occasionally corrupting dcc packets

Revision 1.86  2012/11/18 21:03:41  paolsen
 new (only PIC16F648A version):
   - MiniBOX now recognizes LocoNet OPC_SW_ACK, OPC_SW_STATUS and OPC_SW_REQ, and sends out appropriate AccessoryDecoder DCC packets
 minor change (both versions):
   - Better behaviour of LN-activity blink

Revision 1.77  2011/08/29 15:37:14  paolsen
 new:
   - Added show device id on reconnect (on sl_wr_data)
   - Using CCP1 toghter with timer 1 to handle cd-backoff timing, making HW CD-timer superfluous (for LN-timing, but still in use by ACK-detector)
 changes:
   - Changed FASTBLINK/VERYFAST for full/in-use slot
 bugfix:


Revision 1.65  2011/04/01 18:37:04  paolsen
 new:
   * Added copyright info to EEROM space
 change:
   * Init display with 8888
   * Showing underline not minus when dispatch stack empty
 bugfix:
   * Reimplement Slot Write Accepted LACK(1) => LACK(7F) as it turned out to be a very bad idea since Digitrax cabs don't connect


Rev 1.47 2006/04/11 23:43:01 paolsen
 new:
   - Increased capacity to 8 refresh slots
   - Possible to choose 28FS when entering loco address
   - Support FAST_CLOCK slot, but not running it
   - Support GlobalPowerOn LocoNet-command (GPON)
 change:
   - New loco refresh algorithm
   - Improved 28FS DCC packet generator
   - Slot write (OPC_WR_SL_DATA) to legal slot respond with LACK(1) (as implemented by JMRI)
   - Slot write (OPC_WR_SL_DATA) to PROG_SLOT gives immediate LACK(7F)
 bugfix:
   - Allow Dispatch Put IN_USE slots, but set to COMMON
   - Request (OPC_RQ_SL_DATA) for unsupported slot respond with LACK(7F)
   - Workaround for Daisy in FRED mode (changed response of request for slot 0)


Rev 1.23  2005/11/08 22:48:19  paolsen
 - new:    supporting GlobalPowerOff LN-command
 - change: increased purge time to 75 s (matching UT1)
 - fixed:  better support of Digitrax throttle - tested with UT1


Rev 1.22  2005/10/11 20:00:41  paolsen
 - bugfix: reconnect after address purged could cause loco in several slots


Rev 1.18  2005/01/23 20:19:32  paolsen
 - bugfix: corrected the 28FS (and 14FS) algorithm
 - change: increased default purge time to 64 seconds
