Hardware

The EA uniTFT-Serie consists of a TFT/IPS-Display with LED backlight, driven by an integrated driving circuit, which is dimmable using software commands. In 24/7 operation the backlight can be dimmed automatically to increase the LED life-time and save energy.

The module is designed to work with 3.3 VDC. Serial data transfer is possible through RS232, SPI, I²C or direct via USB protocol.

For simple control tasks, the module has 16 freely usable I/Os (expandable up to 125), 4 analogue inputs, one PWM output and 3 serial interfaces (RS232, SPI and I²C).

Optionally there are two versions with integrated touch panels. By touching the display you can enter data and make adjustments via menu or bar graph. The labelling, size and shape of the "keys" is flexible and can also be changed during runtime (different languages, icons). The drawing of the individual "keys", as well as the labelling is completely taken over by the built-in software. Depending on the application, you may prefer the analogue resistive touch panel, which even can be operated with pen or thick glove, or the capacitive version, which has an robust glass surface that can also be operated with thin gloves.
