Many geometric functions are likewise integrated for displaying bar graphs, frames, and switches, for example. Analog rotary and pointer instruments can be easily visualized using a free application called “LCD Tools”. The display unit features two analog inputs for this purpose.
The optional variant with touch panel makes it possible to operate the display using graphic controls that change dynamically. Up to 40 buttons, switches, or bar graphs can be defined and changed by software, depending on the situation.
Measuring 3.2 inches in the diagonal, the display supports 65,536 colors and has a resolution of 320 x 240. Images and texts can be mixed as desired. Macro pages let the developer realize a multilingual display. The energy-efficient LED background illumination is set via software. To give the developer the greatest level of freedom, the display units provide three different interfaces – RS 232, I2C bus, and SPI bus. The display can be used in an enhanced temperature range of -20 °C to +70 °C.
Its larger counterpart, a 4.3-inch TFT display in 16:9 format, offers the same functions.
