Segment LCD
A single segment LCD component is selected to handle all displays on the LCD glass panel. The
component is used to define all segment assignments for the glass. It presents a grid containing an
entry for each addressable element in the glass. An element can be a pixel in the matrix characters,
a segment of one of the segment displays, or a specific icon built into the display. Each element is
considered a pixel and can be individually addressed at its mapped location and can be turned on or
off using the component pixel handling API calls.
There are also helper functions that can be defined. Each helper is specifically designed to allow
handling of the different types of characters in the display. Thus, segments of a segment character
can be grouped and addressed collectively by a single helper. Each helper has a set of component
API calls that you can place in the code for writing digits or characters to the target display areas.
Each icon is turned on or off using a write pixel API call. The matrix display characters are set using
a write string API call. The segment displays are written one character at a time using a write charac-
ter or write digit API call. For demonstration purposes, the large and small 7-segment characters are
also written using a write number API call which writes the hex or decimal value to the entire set of
large or small 7-segment characters.
In the basic configuration, the bias voltage is selected. To adjust the contrast dynamically, the project
calls the adjust bias API call provided by the segment LCD component. The higher the bias level set
in the call to the API the higher the contrast. The API allows a selection between 0 and 127 with 127
corresponding to the maximum contrast level (see
selected to be the maximum rate before the characters in the display begin to reduce in contrast.
The Hi Drive Time is set to the maximum drive time for the Type B waveform that is selected.
The glass is of type FSTN with a 6 o'clock viewing angle. The drive method is 1/16 Duty, 1/5 Bias.
The operating voltage is 3.3V. The polarizer mode is Reflective/Positive.
