Snowflake Configuration

In version 1.2 of the snowflake firmware, I added a configuration mode, using a button attached to the data in of the first element.

If you own the pre-assembled version from Pimoroni, be aware the power supply voltage is 5V and there is a resistor bridge to limit the voltage to 3.3V on data in.

This post describes the configuration for version 1.2.1 of the firmware. Later fimware versions may add more features to the configuration.

The States

The attached button can issue two actions: a short press and a long press. A short press is anything from 50ms to approximate two seconds, and a long press is any press longer than two seconds.

After the initial power-up of the decoration, it starts in the play animation mode, using the first automatic mode and a one-minute duration for each pattern.

In the play animation mode, a long press will turn the decoration off. If turned off, any button press will turn it on again.

A short press in play animation mode will switch to the configuration. The indicator for the configuration is the fast blinking LEDs around the first snowflake. Use button presses to change the configuration as described below. If you wait for six seconds, the configuration is accepted and the decoration goes back into the play animation mode.

The Configuration

You always start in the mode selection. Short presses will iterate through all auto modes, then through all single modes. After the last single mode, it will start over with the first auto mode.

The LED in the centre indicates an auto mode. The shown LED 1-5 indicate which auto mode is actually selected. After reaching the last auto mode, single pattern modes are selected.

The single pattern mode is indicated with the centre LED off and two LEDs in the inner ring. The two LEDs indicate the page of the pattern and the LED in the outer ring the pattern number. There are six patterns on each page, and after the sixth pattern, you switch to the next page.

After the last pattern, you switch back to auto mode selection.

If you wait for six seconds, the decoration will switch back into the play animation state, using the selecting mode.

A long press switches to the pattern duration configuration.

The Pattern Duration Configuration

In the pattern duration configuration, you select how long a pattern in any auto mode is displayed, before the decoration switches to the next random pattern.
