GENERAL

The EAPLUG-Series provides a simple graphicaldisplaywiththe built-ininstructionset.

Inadditionto various built-infonts,whichcanbe used pixel-perfect, it also offers a whole range of

sophisticated graphics functions. The displayis immediatelyreadyfor operationwith3.3V ... 5V. It

is controlled via one ofthe four built-inserialinterfaces RS232, SPI, I²C or USB.

Programming is via high-levellanguage-like graphics commands; the time-consuming

programming of character sets and graphics routines is completelyeliminated here. The simple use

of this displaywithtouchpanel drasticallyshortens the development time.

HARDWARE

The EA PLUG-Series consists of a OLED display, which is dimmable using software commands.

The most easy way to bring it into operation is via USB. The module is designed to work with

3.3~5V VDD. Furthermore serial data transfer is possible through RS232, SPI and I²C. For simple

control tasks, the module has 8 freely usable I/Os, 2 analog inputs, one PWM and one analog

output.

* Connectors are only included in hardware version Z (e.g. EA PLUGL128G-6TCZ)

SERIAL INTERFACES

The module provides 4 serial interfaces, including USB, RS232, SPI and I²C. All interfaces are

enabled and received data willbe put into one receive buffer. Aprotocol command is provided if an

exclusive interface request is requested.

USB

The Universal Serial Bus is a serial bus system for interfacing a PC with other peripherals. It's

based on differential data transfer. The bus topology is a strict master-slave communication. In the

case of EA PLUG-Series the PC/Master needs to coordinate the communication. The module has

a CDC (Communications Device Class) and is found byWindows PC's as a virtual COM-Port:

Description Value

Device Class 2

USB Vendor ID 0x2DA9

USB Product ID 0x0CE4

Device description EA PLUG

To program the module, adjust settings or to perform initial tests, we recommend using the USB

interface. It's easy to connect, the transfer rate is fast and no interface parameters need to be

specified. The driver for Windows canbe downloaded onour web-page.

If the USB connection is not to be made via the mini-USB connector (J1) but via the primary

connector (J5), two solder bridges must be closed:

Attention:

A protocol has to be used in USB CDC mode. It's impossible to use the USB interface without a

protocol, which means the solder bridge (DPROT) must be kept open. Otherwise the high-speed

connectionof USB leads to buffer overflow.

RS232

RS232 is a standard for a serial interface. The transmission is serially asynchronous. Thus the data

is converted into a bitstream and transmitted. There is no clock signal, so everybus usermust work

withthe same transmissionrate (so-called baud rate). RS232 is a voltage interface, such that data

is transmitted using changing voltage levels. RS232 consists of "listening" and "talking" lines that

are crossed betweenthe two parties. The PLUG fits for direct connectionto a RS-232 interface with

CMOS level (in the case of EAPLUG-Series 3.1 V). If you have an interface with another level, an

external levelshifter is needed.

Inthe EAPLUG-Series,the data format is fixed to 8-N-1:
