9.2.3 Description

The example configures the LCDCA Controller in a mode defined by the LCD glass board connections, and the technical characteristics of the LCD component used. It uses the following LCDCA controller features:

  • LCD contrast control

  • Hardware blinking

  • Autonomous segment animation

  • Automated character (sequential and scrolling)

  • ASCII digit encoder

  • LCD beginning of frame interrupt

The LCDCA is set up to use the external 32.768kHz clock to generate LCD frames at 64Hz, using a low power waveform to reduce toggle activity, and hence power consumption. In order to show the LCD Controller's capability of running in a power-saving mode, sleep mode is entered whenever possible.
