ea edip240-7 page 3 specifications may be changed without prior notice. printing error reserved general the ea edip240-7 is the world?s first display with integrated intelligence! as well as a number of built-in fonts which can be used with pixel accuracy it also features a whole range of sophisticated graphics functions. supplied with 5v, the display is ready for operation immediately. it is controlled via one of the 3 integrated rs- 232, spi or i2c interfaces. graphics commands similar to high-level languages are used for programming. there is no longer any need for the time-consuming programming of character sets and graphics routines. the ease of use of this display with its touch panel reduces development time dramatically. hardware the display is designed to work with an operating voltage of +5v. data transfer is either serial and asynchronous using the rs-232 format or synchronous using the spi or i2c specification. a simple protocol is used for all data transfer variants to improve data reliability. analog touch panel the ea edip240b-7lwtp and ea edip240j-7lwtp versions are equipped with an integrated touch panel. you can make entries and menu or bar graph settings by touching the display. the labeling of the ?keys? is flexible and can also be changed during runtime (different languages, icons). the drawing of the individual ?keys? and the labeling is handled by the integrated software. led backlight, types b and j all displays in blue-and-white (b) and black-and-white (j) are equipped with a modern, low power consumption led backlight. whereas the black&white and the amber-colored display can still be read even when the backlight is switched off completely, the blue-white display requires a minimum level of illumination to be legible. the backlight can be switched off with a software command and the brightness can be adjusted. we recommend the black&white version for use in direct sunlight. for all other applications, we recommend the high-contrast, blue-white version. note that the white led backlight is subject to aging. that means switching off or dimming backlight is a must for 24-hour-applications. not so for the amber backlight. software the display is programmed by means of commands, such as draw a rectangle from (0,0) to (64,15) . no additional software or drivers are required. strings can be placed with pixel accuracy . flashing attributes can be assigned as often as you like ? for graphics as well. text and graphics can be combined at any time. up to 16 different character sets can be used. each one can be zoomed from 2 to 4 times. with the largest character set, the words and numbers displayed will fill the screen. accessories evaluation-board (programmer) for internal data flash memory the display is shipped fully programmed and with all fonts. the additional evaluation-board is thus generally not required. however, if the internal character sets have to be changed or extended, or if images or macros have to be stored internally, the evaluation-board ea 9777-2usb, which is available as an accessory, will burn the data/images you have created into the on-board eeprom (32/64 kb) permanently. the evaluation-board runs under windows and is connected to the pc?s usb interface. it is shipped with an interface cable and the installation software. the evaluation-board is equipped with serveral leds, pushbottons and potentiometer to test all peripherial modes of the edip. interface-expansion for evaluation-board (included in the starter-kit): wtih the expansion ea 9777-2pe for the evaluation-board all interfaces of the display are made available with the help from small adapter boards: rs-232, rs-485, spi, i2c, rs-232 (cmos level). further information you will find in the datasheet of the evalution-board.

ea edip240-7 page 16 specifications may be changed without prior notice. printing error reserved terminal mode the display provides a terminal function. when you switch it on, a cursor flashes in the first line, indicating that the display is ready for operation. all the incoming characters are displayed in ascii format on the terminal (exception: cr,lf,ff,esc,?#?). to achieve this, a correctly functioning protocol frame is required (pages 8 and 9) or the protocol must be deactivated (close solder strap j2, page 8 and 20). line breaks are automatic or can be executed by means of the ?lf? character. if the last line is full, the contents of the terminal scroll upward. the ff character (formfeed) clears the terminal. the character ?#? is used as an escape character and thus cannot be displayed directly on the terminal. if the character ?#? is to be output on the terminal, it must be transmitted twice: ?##?. the terminal has a separate output layer and is thus completely independent of the graphic outputs. if the graphics screen is cleared with ?esc dl?, for example, that does not affect the contents of the terminal window. the terminal font is permanently in rom and can also be used for graphics output ?esc z...?

ea edip240-7 page 17 specifications may be changed without prior notice. printing error reserved fill patterns a pattern type can be set as a parameter with some commands. in this way, rectangular areas and bar graphs for instance can be filled with different patterns. there are 16 internal fill patterns available. using the serial interface the ea edip240-7 can be programmed by means of various integrated commands. each command begins with escape or hash followed by one or two command letters and some parameters. there thus are two ways to send commands: 1. ascii mode - the esc character corresponds to the character ? # ? (hex: $23, dec: 35). - the command letters come directly after the ?#? character. - the parameters are transmitted as plain text (several ascii characters) followed by a separating character (such as a comma ? , ?) - also after the last parameter e.g.: #gd0,0,239,127, - strings (text) are written directly without quotation marks and terminated with cr (hex: $0d) or lf (hex: $0a). 2. binary mode - the escape character corresponds to the character esc (hex: $1b, dec: 27). - the command letters are sent directly. - the x, y coordinates and all the other parameters are transmitted as 8-bit binary values (1 byte). - strings (text) are terminated with cr (hex: $0d) or lf (hex: $0a) or nul (hex: $00). no separating characters, such as spaces or commas, may be used in binary mode. the commands require no final byte , such as a carriage return (apart from the string: $00).
ea edip240-7 page 18 specifications may be changed without prior notice. printing error reserved macro programming single or multiple command sequences can be grouped together in macros and stored in the eeprom. you can then start them by using the run macro commands. there are different types of macro: normal macros (0 through 255) these are started by means of an ?esc mn xx? command via the serial interface or from another macro. a series of macros occurring one after the other can be called cyclically (movie, hourglass, multi-page help text). these automatic macros continue to be processed until a command is received via rs-232 or another macro is activated. furthermore these macros may be started by "macro processes" as an individual task (from v1.1). process macros will not be interupted by any other commands or touch panel use. touch macro (1 through 255) started when you touch/release a touch field (only in versions with a touch panel - tp) or issue an ?esc mt xx? command. menu macro (1 through 255) started when you choose a menu item or issue an ?esc mm xx? command. power-on macro started after power-on. you can switch off the cursor and define an opening screen, for example. reset macro started after an external reset or after a voltage dip under 4.7v (vdd-vss). watchdog macro started after a fault/error (e.g. crash). brown-out macro started after a voltage dip <4v. important: if a continuous loop is programmed in the power-on, reset or watchdog macro, the display can no longer be addressed. in this event, execution of the power-on macro must be suppressed. this is achieved by wiring dpom appropriately. poweroff - connect pin 13 (dpom) to gnd - poweron - disconnect pin 13 again. write protection for macro programming and fonts a vdd line level at pin 19 (eep_wp) prevents inadvertent overwriting of the macros, images and fonts in the eeprom (recommanded in any case!). memory expansion the size of the internal eeprom memory is 32 kb. generally, this allows sufficient space for a large number of images and macros. if, however, a very large number of images (in particular full-size images) are to be stored, it can be necessary to expand the memory. the memory capacity can be doubled by directly connecting a standard eeprom of the 24c256 series. it is connected over pins 17, 18 and 19 (i2c adress $a6) or can be placed direct as u12 (see drawing on page 20).
