TME: creating visually attractive interfaces with NerO and CleO
CleO intelligent display modules, manufactured by Bridgetek, are an interesting alternative for electronics engineers who intend to equip their application with an attention-grabbing and attractive graphical user interface. Regardless of your previous experience in design, CleO intelligent display modules are worth considering. They are compatible with ARDUINO standard and they can work with the popular ARDUINO UNO platform.
Bridgetek has developed its own platform version, the NerO board, which is compatible with CleO display modules. The basic advantage of NerO board is a switched voltage regulator. Its current efficiency amounts to 1A@5VDC within a wide operating voltage input (7 VDC-20 VDC) supplied from external power source. What is more, even at maximum load, the board works stable and the regulator does not overheat.
The NerO kit features ATMEGA328 microcontroller with 16MHz clock and built-in bootloader; communication between microcontroller and computer via micro USB (FT231X integrated circuit as a USB-UART bridge); LEDs signalling operation mode of the kit, placed on the edge of PCB; ON/OFF switch.
Tests conducted under the same conditions with ARDUINO UNO board show that maximum value of output current in case of ARDUINO does not exceed 0.8 mA for input voltage of 9 VDC and 0.6 mA for input voltage of 12 VDC. Therefore, it is important to provide sufficiently large current efficiency. Especially given the fact that CleO35 display module, which is supposed to work with the board, consumes current of 150 mA. In case of connecting a camera with LED backlight to the display module, the display consumes current of 250 mA, and in case of a 1W speaker, this value increases to 450 mA.
CleoO display modules allow for creating visually attractive interfaces. The process is easy, so even users who do not have detailed knowledge about graphic applications will cope with this task. It is possible thanks to the fact that CleO intelligent display modules are compatible with NerO/ARDUINO boards which can be programmed in ARDUINO IDE environment.
On the website www.cleostuff.com you will find libraries for ARDUINO IDE environment. They contain 21 example projects designed for the NerO and CleO duo. In CleO help section, there is an extensive handbook divided into 20 chapters. It covers over 80 topics connected with programming graphic applications for this platform. In order for the NerO board to operate properly, VCP drivers from FTDI website have to be installed.
