2.1 Serial Command Protocol
The following applies only to the Serial Platform and each serial command
is described in detail and how it can be used. Please note that all
command examples listed in this section are in hex (00hex). Due to the
high colour depth of the display module, a pixel colour value will not fit
into a single byte, a byte can only hold a maximum value of 255.
Therefore the colour is represented as a 2 byte value, colour(msb:lsb).
The most significant byte (msb) is transmitted first followed by the least
significant byte (lsb). This format is called the big endian. So for a 2 byte
colour
value
of
013Fhex
the
byte
order
can
be
shown
as
(01hex),(3Fhex).
NOTE:
When transmitting the command and data
bytes,
do not include
any separators such as commas ‘,’ or spaces ‘ ‘ or brackets ‘(‘ ‘)’ between
the bytes. The examples show these separators purely for legibility; these
must not be included when transmitting data to the
µOLED-128-G1
module.
Serial Interface:
The
µOLED-128-G1
needs to be connected via a serial link to a host
system. The host uses this serial link to send commands to the module so
that characters and graphics can be displayed on the screen. Use the
signal pin-outs as well as the application example shown in the “User
Interface” section for correct connection to the host.
Auto Baud Detect:
As previously mentioned, the module has an auto-baud detect feature
which can operate from 300 baud to 256K baud. Prior to any
commands being sent to the module, it must first be initialized by sending
the ASCII character ‘U’ (55h) after power-up. This will allow the module
to determine and lock on to the baud rate of the host automatically
without needing any further setup. This must be done every time the
module is powered up or reset.
If the host needs to change the baud rate, the module must be powered
down and powered back up again or reset. The “U” command cannot be
used to change the baud rate during the middle of normal usage.
