Demoboard with EA uniTFTs028-ATC: EA DEMOPACK-WiFiBT
EA DEMOPACK-WiFiBT shows how to use the EA uniTFTs028-ATC smart display with Wi-Fi and Bluetooth communication added.
The DEMOPACK-WiFiBT board includes the ESP32 processor to add Wi-Fi and Bluetooth communication to the display. The ESP32 communicates with the EA uniTFTs028-ATC smart display via the RS232 interface. Additionally the display SBUF-output is connected to the ESP32 IO32. The SBUF-output pin indicates that data is ready in the display send buffer. The EA uniTFTs028-ATC IO0.0 is connected the the ESP32 IO33 to interrupt direct Bluetooth connection. More IO onboard the smart display and the ESP32 are available for use. The project for the ESP32-WROOM-32 is fully documented and shows how to connect a Bluetooth keyboard to the display and another example using Wi-Fi shows how to retrieve weather information from https://openweathermap.org and display the weather forecast on the smart display. The familiar Arduino IDE is used to program the ESP32 processor.
The EA uniTFTs028-ATC 2.8" IPS TFT smart display with PCAP touch-screen is included with this EA DEMOPACK-WiFiBT. The EA uniTFT(s) displays can be programmed as a stand-alone HMI controller with low voltage inputs and outputs. Onboard the displays is a USB port, serial, I²C and SPI (3.3V) interface. This DEMOPACK-WiFiBT has an onboard voltage regulator for supply voltages from 5 to 28V DC.
Easily control and create HMI screens with the Windows uniTFTDesigner software and adapt the many examples provided. The uniTFTDesigner software includes a display simulator, this speeds up development time as picture position and functions can be checked on your desktop without the need to download the project into the display.
Should your project require a smaller or larger display then do not worry, the EA uniTFTs smart displays are available in size 2.0", 2.8", 3.5" and 4.3" with the same ZIFF connector. Additionally larger and more powerful uniTFT displays are available in size 5.0", 7.0" and 10.1". The EA uniTFT(s) smart displays designed by Display Visons and distributed by MMS Electronics Ltd are recommended for new designs.
Orders are currently restricted to one DEMOPACK-WIFi per customer. This DEMOPACK can now be pre-order.
