Firmware v1.2.0

Changes in this release:

• The firmware has been adjusted for PIC16(L)F18326
• A bug that caused resetting manual output override on passing scheduler segment boundaries (at :30 and :00) has been fixed
• The output controller logic has been improved and cleaned-up
• The splash screen now has a reset reason indicator (MCLR, stack over/underflow etc.)
• I²C speed has been reduced to 400 kHz for more stability in low input voltage situations
• Diode voltage drop configuration value has been updated for BAT54C
• The debug indicator has been extended with the states of the output controller

Firmware v1.0.4

Changes in this release:

• Sleep mode behavior is significantly improved
  • Spend less time in awake state by skipping unnecessary heavy tasks
  • Fixed an issue when the LED output was flashing output after the external power returned
• Disabled debug-related code and EUSART peripheral by default to save space and power
• Added visual debug state indicator

Firmware v1.0.3

Changes in this release:

• Reset the RTC seconds counter on changing the time

Firmware v1.0.2

• Fix missing title for clock settings
• Add setting for display brightness
• Decrease the MCU clock speed to 16 MHz to save power

Firmware v1.0.0

First release of the firmware.

The planned features are implemented, including:

• Turning the output on/off based on the programmed schedule
• Turning the output on/off on-demand temporarily, until the next schedule state change occurs
• Easy to understand screens with indicators and key cheat-sheet
• Settings screen to adjust the schedule and the LED output brightness (PWM duty cycle)
• Settings saved to and loaded from the internal EEPROM
• Automatic detection of main power loss and enabling power-saving features while running on the backup battery
• Time keeping even when the main power is lost
• Backup battery level indication on the main screen
