ELECTRONIC ASSEMBLY reserves the right to change specifications without prior notice. Printing and typographical errors reserved. EA eDIPTFT70-A Page 3 GENERAL The EA eDIP series of displays are the world’s first displays with integrated intelligence. In addition to a variety of integrated fonts that can be used with pixel accuracy, they offer a whole range of sophisticated graphics functions. They are controlled via one of the 3 integrated interfaces: RS-232, SPI or I²C.

EA eDIPTFT70-A Page 4 RS-232 INTERFACE If the display is wired as shown below, the RS-232 interface is selected. The pin assignment is specified in the table on the right. The RxD and TxD lines lead CMOS level (5V) for direct connection to a microcontroller for example. If “genuine” RS-232 levels are required (e.g. for connection to a PC), an external level converter (e.g.

EA eDIPTFT70-A Page 5 APPLICATION EXAMPLE „REAL“ RS-232 INTERFACE The eDIP fits for direct connection to a RS-232 interface with CMOS level (5V). If you have an interface with ±12V level, an external levelshifter is needed. application example APPLICATION EXAMPLE: RS-485 INTERFACE With an external converter (e.g. SN75176), the EA eDIP can be connected to a 2-wire RS-485 bus.
ELECTRONIC ASSEMBLY reserves the right to change specifications without prior notice. Printing and typographical errors reserved. EA eDIPTFT70-A Page 6 SPI INTERFACE If the display is wired as shown below, SPI mode is activated. The data is then transferred via the serial, synchronous SPI interface. The transfer parameter will be set via the pins DORD, CPOL and CPHA.
ELECTRONIC ASSEMBLY reserves the right to change specifications without prior notice. Printing and typographical errors reserved. I²C-BUS INTERFACE If the display is wired as shown below, it can be operated directly to the I²C bus. 8 different base addresses and 8 slave addresses can be selected on the display. Data transfer is possible at up to 100 kHz. However, if pauses of at least 100 µs are maintained between the individual bytes during transfer, a byte can be transferred at up to 400 kHz.

ANALOGUE INPUT AIN1 AND AIN2 (PIN 31+32) For analogue measurement 2 inputs with a range of 0..+5V are available. Each input is grounded (GND) and DC impedance is 1MΩ. Please make sure that only positive voltages will be supplied there. Internal resolution is 10 Bit, equal to a 3-digit DVM modul. Linearity (after adjustment) is around 0.5%.

EA eDIPTFT70-A Page 9 EXTERNAL KEYBOARD A keyboard (anything from individual keys to a 8x8 matrix keyboard) can be connected to the I/O- ports. The command ‘ESC Y M n1 n2 n3’ defines the count of input lines (n1=1..8) and output lines (n2=1..8). n3 set debounce function with 10ms steps (n3=0..15).

EA eDIPTFT70-A Page 10 DATA TRANSFER PROTOCOL (SMALL PROTOCOL) The protocol has an identical structure for all 3 interface types: RS-232, SPI and I²C. Each data transfer is embedded in a fixed frame with a checksum (protocol package).

TERMINAL MODE When you switch the unit on, the 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,’#’). The prerequisite for this is a working protocol frame or a deactivated protocol (see pages 10 and 11).

DEFINE OWN BORDER With the LCD-tools it is possible to define new borders (Compileroption "Border:"). Each of these new border is a bitmap with exactly 24x24 dots (9 segments with 8x8 dots: 4x edge, 4x middle part, 1x filling). Scaling for bigger touchkeys/frames will be done by repetition of these 8x8 dot segments.

EA eDIPTFT70-A Page 27 Some examples of instruments: BUTTONS AS KEYS Apart from the border types, which are infinitely scalable, it is also possible to use bitmaps as touch keys or touch switches (Compilerotion "Button:"). A button always consists of two Bitmaps of equal size (one bitmap to display the touch key in its normal state and another for when it is pressed).
