19.4 Basic LCD capabilities
This section shows how to use the LCD driver. For each multiplexing configuration it gives a basic example
explaining how to set-up the driver, the generated waveforms, how to connect the display and how to use the on-
chip voltage generator. Other connection schemes and more advanced control functions will be given in the next
section.
The LCD module generates the timing control to drive a static or multiplexed LCD panel, with support for up to 32
segment lines multiplexed with up to four common lines. The table below summarises the multiplexing scheme for
LCD operation.
