CHANGELOG

Change Log

vD3.9.5 SCL 20150722
- merge changes from temp branch:
	1. EVSE goes to sleep after time/charge limit met.. would stay in sleep
	-> automatically cancel sleep mode when car disconnected *only if* the
	   sleep was induced by time/charge limit
	2. decouple temperature monitoring from J1772EVSEController::Update()
	-> so that temperature is still monitored when EVSE disabled/sleeping
	3. ProcessInputs() removed from J1772EVSEController
	4. added TEMPERATURE_MONITORING_NY (not yet) code .. currently disabled
	-> $GO/$SO RAPI 
	-> added ambient/ir_thresh support
	
vD3.9.4 SCL 20150611
- reduce GFI self test pulse duration from 50% to 33%

- craigK PR #46
	
vD3.9.3 SCL 20150608
- add files and edits to restore I2CLCD_PCF8574 build capability

vD3.9.0 SCL 20150604-5
- split out Gfi/J1772Pilot/J1772EvseController into separate files
- add support for changing I2C frequency
- increase I2C bus from 100KHz -> 200KHz
- use modified local Wire/twi to get rid of digitalWrite()
- on POST failure, go directly to Setup menu. Setup menu exits to reboot on POST failure
- shrink MaxCurrent/ChargeLimit/TimeLimit menu memory/code by calculating allowed
	values rather than using RAM lookup tables
- put strings in strings.cpp
- fix bugs from 3.8.4: 1) Setup menu Exit sometimes didn't work 2) Setup menu would
	start on Exit item after first use
- GFCI and No Ground faults auto reset when EV is unplugged, even if hard fault
- GFCI and No Ground faults display auto reset countdown when applicable
	GFCI FAULT
	RETRY IN 04:55
- when waiting for timer, just display Sleeping instead of Waiting
- during a fault, short press goes directly to Setup menu instead of putting
	EVSE in Sleep state
- send $WF WIFI_MODE_AP_DEFAULT instead of WIFI_MODE_AP to client on very long
	button press
- fix RAPI bug: $GF was returning FF as trip counts if zero. New max value for
	any trip count = FE
- fix documentation for $SC & $GG
- got rid of superfluous AUTOSTART_MENU and MANUALSTART code
- fixes for TEMPERATURE_MONITORING from CraigK
- fix bugs in Charging screen when KWH_RECORDING or TEMPERATURE_MONITORING not defined

vD3.8.4 SCL 20150526
- display "Disabled" when EVSE_STATE_DISABLED instead of "Stopped"
- fix bug: RAPI wasn't sending EVSE state ($ST) properly
	
vD3.8.3 SCL 20150518
- fix RAPI bug caused by code compaction in 3.8.x
- have Setup menu exit out of menus instead of back to Settings
	
vD3.8.2 SCL 20150518
- got rid of LcdDetected() .. superfluous, since LiquidTWI2 handles it
	
vD3.8.1 SCL 20150516
- fix bug in settings menu - charge & time limit should only display when EV connected
- when charge or time limit set, exit directly out of menus
- display clock icon when time limit set, lightning bolt icon when charge limit set
- code compaction
	
vD3.8.0 SCL 20150516
- added TIME_LIMIT - charge for a specified time and stop
	
vD3.7.9 SCL 20150515
- fix bug in u2a() when digits=0
- added CHARGE_LIMIT - charge to a certain kWh and then go to sleep
  kudos to AndreE for the charge limit idea.
- move all setup menus to separate "Setup" submenu. Top level menu now
  called "Settings"
	
SCL 20150513
- cleanup, move SERIALCLI to serialcli.cpp/h

vD3.7.2 SCL 20150428
- added SHOW_DISABLED_TESTS
- try to fix random GFI fault due to UL-mandated GFI self test just before

- disable OnboardDisplay::Update() when in menu
- GFI hard fault .. change status to EVSE_STATE_GFI_TEST_FAILED instead of EVSE_GFCI_FAULT
- when rebooting EVSE if our relay is closed, set pilot to +12VDC and wait 3 sec
	to give EV time to open its contactor before we open ours

1. Gut ReadACPins(). It s unused.
2. GROUND_TEST_PIN is gone in the 1.0 hardware.
3. RELAY_TEST_PIN is high when charging or it s a ground fail. It s low
when not charging or it s a stuck relay.

vD3.5.1 SCL 20150218
- added FT_GFI_LOCKOUT/FT_GFI_RETRY for functional testing
- per UL Fred Reyes, stuck relay always results in hard fault (lockout)
- GFI_RETRY_COUNT to 255 (infinite) instead of 15

vD3.5.0 SCL 20150216
- added UL_COMPLIANT: UL wants EVSE to hard fault (cease operation until manual intervention)
  1) if POST fails
  2) if fault happens immediately after charge starts
- consolidated some redundant fault strings
- if AutoSvcLevel couldn't be detected due to car being plugged in during POST,
  and L1 was set because of this, upon first charge session, we will detect the
  actual svc level, and switch to L2 if detected

vD3.4.3 SCL 20150213
- don't do GFI self test in doPost() if other fault already found
- when in menus, lock out all other functions until exit 
- do stuck relay chk in POST even if EV is plugged in and AutoSvcLevel()
- for safety, set to L1 if AutoSvcLevel and car is plugged in during POST,
  because we can't auto detect level.

vD3.4.2 SCL 20150210
- added SLEEP_STATUS_PIN
	
vD3.4.1 SCL 20150205
- forgot to set svcState to SR when stuck relay test fails in doPost() and
	not AutoSvcLevel()
	
vD3.4.0 SCL 20150123
- added writing of safety check trip counters to EEPROM
- added RAPI $GF
- setting GFI_RETRY_COUNT to 255 will make it retry indefinitely
- changed GFI_RETRY_COUNT from 3 to 15, GFI_TIMEOUT from 15min to 1min
  -> now, tests will retry 15 times at one minute intervals
     instead of 3 retries at 15 min intervals
