Demoboard for uniTFTs EA DEMOPACK-CLIMA
Demo application for EA uniTFTs028 display with application PCB for CO2 measurement, temperature measurement and humidity measurement via I²C.
The Si7020-A20 sensor is used for the temperature and humidity measurement and CSS811B-JOPD500 for the CO2 sensor.
This applications shows communication of the sensors and Real-Time-Clock (RTC) via I²C. RTC is battery buffered. Demoboard has a reset switch and test points for GND and VDD.
The display included is the SMART EA uniTFTs028-ATC 2.8" TFT with PCAP touch-screen and powerful graphics functions, memory and touch panel support. The uniTFT(s) displays can be programmed as stand-alone HMI controller with inputs and outputs. Display interface is USB (5V), serial, I²C and SPI (3.3V). A level converter is required for RS-232 (+/-12V). For examples of an application using a RS-232, RS-485 level converter check out part: EA DEMOPACK-CONNI.
Move objects on the display, change measured values while they are displayed, automatically enlarge important parameters, show and hide controls.
The EA uniTFTs028-ATC is programmed with the new drag and drop uniTFTDesigner software for Windows™.
