I²C-BUS INTERFACE
If the display is wired as shown below, it can
be operated directly on an 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.
Note:
On pin 20 (SBUF) the display indicates with a low level that data
is ready to be retrieved from the internal send buffer. The line
can be connected to an interrupt input of the host system, for
example.
Note:
The pins BA0 to 2, SA0 to 2, DPOM, DPROT and TEST/SBUF have an internal pullup, which is why only the LO level (L=0=GND) is to be
actively applied. These pins must be left open for a Hi level (H=1).
On pin 20 (SBUF) the display indicates with a low level that data is ready to be retrieved from the internal send buffer.
The line can be connected to an interrupt input of the host system, for example.
DATA TRANSFER I²C-BUS
principle I2C-bus transfer:
Read operation: for internal
operation the EA eDIP does need
a short time before providing the
data; therefore a short pause of
min. 6µs is needed for each byte
(no activity of SCL line).
