Intelligent LCD with PCAP touch screen for demanding environments
The 5.0", 5.7" and 7.0 iLCD's from Demmel Products are now available with projected capacitive (PCAP) touch screen. The iLCD's with capacitive touch screen supports multi touch operating. Finger movements are reported via the interface to your control application. These iLCDs can be placed behind glass of 4mm thickness. This provides good protection against rough handling or vandalism. The temperature range is -20 to 70°C which allows usage of the iLCD outdoors. You control the iLCD via I2C, RS232, RS422/485 or USB with high level commands. The configuration of all iLCD and PCAP function is easily set with the free iLCD Manager XE.
With the BLE Nano a Bluetooth Smart application is easily developed
BLE Nano is the smallest Bluetooth 4.1 Low Energy (BLE) development board on the market. The core is a Nordic nRF51822 (ARM Cortex-M0 SoC with BLE) which runs on 16MHz with very little power consuption. The MK20 USB board is designed to load new firmware in the BLE Nano. The software development can be done with mbed.org, GCC, Keil or Arduino. There are many libraries and examples available. It works with the free Android App and iOS app from RedBearLab.
