Making Configuration Changes

You can alter the appearance and behaviour of you clock using the web interface (if it is on the Wifi network) or using the buttons on the back.

Web Interface

Visit the web interface for your clock at http://IPADDRESS:8000/config, where IPADDRESS is the IP Address your RPI was assigned or you fixed during the installation phase.

You should arrive at the following screen:

The options are as follows:

*(note that no changes happen on the clock until you press the Save Configuration button)*

• "Show It Is" - changes between showing "It is ten past one" and "ten past one"
• "Show A" - changes between "It is a quarter past one" and "it is quarter past one"
• "Interval" - how often the clock updates (most relevant for the edge modes) - probably leave this at 0.5s unless the edge mode is too fast, in which case you can slow it down
• "Light color" - sets the color of the letters showing the time
• "Mode" - sets what is displayed on the clock and edge
• Modes that show the time
• Normal - shows the time. You would have this set unless you are specifically trying to test something in which case you can turn it off
• Modes that alter what is shown on the edge of the clock
• EdgeLightBlank - the edge lights are not lit
• EdgeLightCustom - the edge lights show the weather (see below)
• EdgeLightGW - edge lights show green and white pattern
• EdgeLightRWB - edge lights show red, white and blue pattern
• EdgeLightSeconds - a seconds marker moves around the edge
• Modes used for testing
• Config - used internally - do not use
• FlashWords - flashes all the words on the display. Use this if you think there is an LED issue
• ShowIPAddress - shows the IP address of the clock in case it changed. You can get to this with the button presses!
• TestEdge - flashes all the edge lights. Use this if you think there is an LED issue
• TestWords - flashes all the word on the clock face in sequence

• Update clock software from Github - Updates the code that the clock is running by pulling the latest code from Github
• Reboot clock - reboots the clock. Use this after doing the update from Github or if the clock seems to have frozen
• Save Configuration - saves and changes you made above and sends it to the clock

Buttons

The buttons on the back of the clock are used to dynamically change the clock. The two buttons are:

• Left button - MODE button
• Switches between modes of the clock
• Right button - ACTION button
• The action depends on the mode of the clock

• NORMAL - shows the time and whatever edge mode you have selected
• CHANGE HOURS - allows you to manually change the current hour (useful if you are not on WIFI)
• CHANGE MINUTES - allows you to manually change the current hour (useful if you are not on WIFI)
• CONNECT TO WIFI - initiates the process to automatically connect to WIFI by reading a QG code and using that to define the network SSID and password
• SHOW WIFI - (when network connection succeeded) shows the current IP address
• FAILED - (when QR code reading or network connection failed) shows that the process did not succeed and waits for the user to clear the state

The overall flow chart is shown by the picture below, with the colours of the modes showing the corresponding colour of the clock edge during the process.

Changing the Hours

If the clock is not on Wifi then you will need to adjust the time manually, for instance during daylight savings time.

Press the MODE button once, then the clock turns purple. Pressing the ACTION button advances the hours one at a time.

Stop pressing buttons and the clock will count down and then switch back to normal mode with the hours updated.

Changing the Minutes

Similarly, if the clock is not on WIFI then you may need to change the minutes.

Press the MODE button twice, then the clock turns yellow . Pressing the ACTION button advances the hours one at a time.

Stop pressing buttons and the clock will count down and then switch back to normal mode with the minutes updated.
