Blink Mode and Frequency Configuration

SLCD can be configured to blink all or selected LCD segments. Segments will alternate between ON and OFF state at the frequency given by the selected frame counter.

The blinking feature is configured in the Blink Configuration register (BCFG):

Blink all the segments
Writing ‘0’ to the Blinking Mode bit (BCFG.MODE) will blink all the segments.

In Blink selected segments mode up to sixteen segments can be enabled individually to blink, which are connected to SEG0, SEG1, and COM[0..7]
Write ‘1’ to the Blinking Mode bit (BCFG.MODE).

Write ‘1’ to the “Blink Segment Selection 0” bits (BCFG.BSS0) enables to blink the respective segments in segment 0 (SEG0), connected to COM0 up to COM7.

Write ‘1’ to the “Blink Segment Selection 1” bits (BCFG.BSS1) enables to blink the respective segments in segment 1 (SEG1), connected to COM0 up to COM7.

Note:

A segment will blink only if it is already ON - otherwise it will remain OFF.

In this case for the Segment LCD1 Xplained Pro LCD glass maximum we have four COM lines. Segment 0 and segment 1 are both connected to COM0 to COM3. Maximum eight segments can be configured to blink individually.

The blink frequency is defined by the frame counter. We can associate any one of the frame counters to the blink feature by writing the corresponding frame counter x index to the Frame Counter Selection bits in the BCFG register (BCFG.FCS).
Once the desired blink configuration is written to the BCFG register, blinking is enabled by writing a '1' to Blink bit in Control C register (CTRLC.BLINK). Blinking is disabled by writing a '0' to CTRLC.BLINK.

Note:

The BCFG register cannot be written when blink is enabled. The blink frequency can be modified. Before updating the new blink frequency the selected frame counter has been disabled.
