HCS08 Family
This application note describes how to interface an
HCS08 device to an OLED display. Organic
light-emitting diode (OLED) displays can provide a
graphical user interface to various applications. They can
be found in television screens, MP3 players, portable
meters (electrical, medical), home automation
equipment (thermostats, alarm controls), mobile phones,
vending machines, coffee machines, white goods, etc.
The code was written for MCUs with limited RAM and
flash memory, with a minimum of I/Os used to drive an
OSRAM Pictiva 128x64 OLED Display, Elegance
Yellow with 16 gray scales (Part No.
OS128064PK27MY0B00). The code is provided as a zip
file, AN3415SW.zip, and can be downloaded from the
Freescale website, www.freescale.com. The example
code can be easily modified for other OLED displays.

OLED Display Description
OLED. The OLED daughter card contains the interface, a DC/DC converter to provide the OLED voltage
(12 V), and the actual OLED display itself.
The OLED displays are a self-emissive technology that typically require less power than LCDs with
backlights. Only an “on” pixel consumes power. This feature makes OLED displays suitable for
battery-powered devices.
Advantages of OLED displays:
• Less power than LCDs — Better for portable/handheld applications
• Self-emissive technology
• Vivid color — High brightness and contrast
• Video capability
• Wide viewing angle
• Thin form factor — No backlight required
• Long-lasting lifetime — Up to 55,000 hours
• Monochrome (yellow, orange, green, white, blue) with one- or four-bit gray-scale capability
• Full color capability
1 OLED Display Description
The OLED display used in this application note offers a parallel- or serial-interface-connection option. The
BS1 and BS2 pins are used to select the interface to be used. In this example only the serial interface is
used (Figure 1).

Figure 1. OLED Module Interface (Serial Mode)
The main advantage of using the serial interface rather than the parallel interface is the number of I/Os
required to drive the display. For the serial interface, only 5 I/Os (D/C, CS, SDIN, SCLK, RST) are
required, compared with 13 I/Os (D/C, CS, R/W, E/RD, D0:D7, RST) for the parallel interface.

and V SS.
4 IREFH Segment (column) current reference — A resistor should be connected between

30 VSL Voltage segment low — A capacitor should be connected between this pin and

The OLED display contains a chip-on-glass (COG) controller (SSD0323 128 x 80, 16 Gray Scale Dot
Matrix OLED/PLED Segment/Common Driver with Controller from Solomon Systech) with display
RAM (graphic display data RAM — GDDRAM) that holds the data for the pattern/images to be displayed.
Four bits of data are required for each pixel (4 bpp = bits per pixel) allowing 16 possible gray values. One
byte is used to store the information for two pixels. In total, 4 Kbytes (4096 bytes) are required to hold the
complete display content for the 128_x_64 pixels. The MCU needs to transfer data only if the display
content needs updated. Cyclic refresh of the display is not necessary .
The data transfer is done byte-wise, first sending the most significant bit (MSB) (Figure 2). The data is
applied with the rising edge of the SCLK signal and is sampled at the falling edge of the SCLK signal. The
data/command signal D/C is used to distinguish between graphic display data access and control
commands sent to the display. Table 3 outlines the available display-control commands.

Figure 2. Serial Data Transfer (Command)
The display data is sent byte-by-byte. Each byte automatically increments the address pointer to the next
position. The display supports different GDDRAM to pixel mappings for mounting flexibility (regarding
display orientation). You can rotate the display output by 180 degrees. Figure 3 and Table 2 show the
default pixel mapping the software uses.

OLED Display Description
To update a portion of the display partially, you can use the set-column-address and set-row-address
commands. They allow defining a portion (canvas) of the display to be updated without updating the whole
128 x 64 pixels. Also, each transferred data byte increases the address pointer to the next (two) pixel within
the defined area. Basically, this mechanism allows you to individually update any (two) pixel (respectively,
any byte in the GDDRAM).
One constraint of using the serial interface is that it supports only unidirectional data transfer (write-only).
Basically, in the serial mode you cannot read back the GDDRAM content; you cannot update only a single
pixel of two pixel in a byte by using a read-modify-write one byte method.

OLED Display Description
Set Re-map 2 bytes This command changes the mapping between the display data
column address and segment driver, row address and common
driver. It allows flexibility in layout during OLED module assembly.
Column Address Re-map
If column address re-map is set, columns 0–63 map to
SEG127–0, regardless of star-column and end-column
commands.
Nibble Re-map
If nibble re-map is set, the two nibbles of the data bus for RAM
access are re-mapped, such that B7, B6, B5, B4, B3, B2, B1, B0
acts like B3, B2, B1, B0, B7, B6, B5, B4.
This feature working with column address re-map produces an
effect of flipping outputs SEG0–127 to SEG127–SEG0.
Address Increment Mode
If horizontal increment mode is set, the column address pointer
advances after each RAM access. If vertical increment mode is
set, the row-address pointer advances after each RAM access.
COM Re-map
If COM re-map is set, ROW 0–79 maps to COM79–0, regardless
of start and end row commands.

Set Display Offset 2 bytes This command is to set the display-offset register to determine the
mapping of the display start line to one of COM0–79. (It is
assumed that COM0 is the display start line, display start line
register equals 0.)
For example, to move the COMX toward the COM0 direction for L
lines, the 7-bit data in the second command should be given by L.
In other words, to move the COMX towards the COM79 direction
for L lines, the 7-bit data in the second command should be given
by 80–L.
Second byte A[6:0] sets the vertical scroll by COM from 0–79.

Normal Display turns the data to ON at the corresponding gray
levels GS0–GS15 (see Set Gray Scale Table).
Entire Display On forces the entire display to be at gray level
GS15, regardless of the contents of the display data RAM.
Entire Display Off forces the entire display to be at gray level GS0
regardless of the contents of the display data RAM.
Inverse Display uses the gray scale table in reverse order gray
level 0–15 uses GS15–GS0, and so on.
0xA4 = Normal Display (POR)
0xA5 = Entire Display On (GS15)
0xA6 = Entire Display Off (GS0)
0xA7 = Inverse Display
Set Multiplex Ratio 2 bytes This command sets multiplex ratio N from 16 to 80.
Second byte A[6:0] determines multiplex ration N. POR = 0x4F
(80).
Set Master Configuration 2 bytes This command is used to enable or disable the internal DC–DC
voltage converter. This command is executed when display is on.
A[0] = 0, Disable DC–DC converter
A[0] = 1, Enable DC–DC converter (POR)
A[1] = 0, Disable internal VCOMH
A[1] = 1, Enable internal VCOMH (POR)

2 bytes This command is used to set segment low voltage (VSL). The
value of VSL is the same for display all on, display all off pattern
with internal or external DC–DC voltage converter.
The second byte A[3:0] sets the VSL voltage as follow: 1000–1110
A[3:0] = 0010 connects to V SS
A[3:0] = 1110 (POR)
(When V DD > 2.5 V)
Set VCOMH Voltage 2 bytes This command is used to set VCOMH voltage level.
The second byte A[5:0] specifies the VCOMH voltage level
000000–011111
A[5:0] = 1xxxxx = 1.0*VREF
A[5:0] = 010001(POR)
Set Pre-charge Voltage 2 bytes This command is used to set the pre-charge voltage level.
The second byte A[7:0] sets the pre-charge voltage level
00000000–00011111
A[7:0] = 1xxxxxxx connects to VCOMH
A[7:0] = 001xxxxx equals 1.0*VREF
A[7:0] = 00011000(POR)
Set Phase Length 2 bytes This command sets the phase length. The lower nibble of the
second byte selects phase 1 period (no pre-charge and current
drive) from 1 to 16 DCLKs. The higher nibble of the second byte
is used to select phase 2 period (pre-charge) from 1 to 16 DCLKs.
A[3:0] = P1, phase 1 period of 1–15 DCLK clocks, POR = 3DCLKS
= 3
A[7:4] = P2, phase 2 period of 1–15 DCLK clocks, POR = 5DCLKS
= 5
Set Row Period 2 bytes This command is used to set the row period. It is defined by
multiplying the internal display clock period by the number of
DCLKSs per row (value from 2–158).
The larger the value, the more precise tuning of each gray scale
level. See set gray scale table command for details.
Also, it is used to define the frame frequency with the display clock
divide ratio command.
Row period equal to the sum of phase 1, 2 periods and the pulse
width of GS15.
Second byte sets the number of DCLKs, K, per row between
2–158DCLKS, POR = 37DCLKS = 0x25
The K value should be set as K = P1+P2+GS15 pulse width (POR:
3+5+29DCLKS)

Set Display Clock Divide
Ratio/Oscillator
Frequency
2 bytes This command is used to set the frequency of the internal display
clocks, DCLKs. It is defined by dividing the oscillator frequency by
the divide ratio (Value from 1 to 16). Frame frequency is
determined by divide ratio, number of display clocks per row, MUX
ratio and oscillator frequency.
The lower nibble of the second byte is used to select the oscillator
frequency.
The lower nibble of the next byte sets the divide ratio of the display
clocks: Divide ratio = 1–16, POR = 2
The higher nibble of the next byte sets the Oscillator Frequency.
Oscillator Frequency increases with the value of A[7:4] and vice
versa. POR=0
Set Gray Scale Table 9 bytes This command is used to set the gray scale table for the display.
The next 8 bytes set the gray scale level of GS1–15 as below:

OLED Daughter Card
The OLED daughter card allows the OLED display to connect to the DEMO9S08QG8 or
DEMO9S08AW60 demo boards. The OLED daughter card contains the socket for the flat flex cable (FFC)
of the OLED display, a DC/DC converter (12 V, 120 mA boost converter) to supply the OLED display with
the necessary 12 V derived from the 3.3 V supply of the DEMO9S08AW60 and DEMO9S08QG8 boards.
It has two separate 0.1-inch pinheader connectors, J1 and J2, that can be directly connected to the
DEMO9S08AW60 and DEMO9S08QG8 boards, respectively.
Further details of the OLED Daughter Card, like schematics, layout and bill of materials (BOM), can be
found in Section Appendix A, “OLED Daughter Card.”
2.1.1 Interface
• OLED daughter-card interface — Requires six signals and two power-supply connections (Table 6,
Table 7).
• MCU serial peripheral interface — Used to transfer data and commands to the OLED display.
Three SPI pins—slave select (SS), serial clock (SPSCK), and master-out slave-in (MOSI)—are
used for the unidirectional data flow from the MCU to the OLED display. The master-in slave-out
(MISO) pin is available for other use.
• 12VEN signal — Controls DC/DC converter output voltage. Allows a controlled power up/down
of the OLED power voltage V CC .

• RST signal — Connected to an MCU general-purpose input output (GPIO) pin to control the
OLED display hardware reset by software.

The OLED.H header file can adapt the driver for different microcontrollers. Currently, it supports the
MC9S08QG8 and the MC9S08AW60 MCUs.
To change the microcontroller, click on the “Change MCU/Connection ...” button and select the MCU
derivative and the debugger connection you want to use (Figure 8 and Figure 9).
NOTE
You must select the correct MCU derivative and debugger interface to
download the software into the microcontroller flash memory.

The CodeWarrior IDE automatically modifies the DERIVATIVE.H file and inclues the right MCU
derivative files.
For example, after changing to the MC9S08QG8 MCU the DERIVATIVE.H file looks like this:
/*
* Note: This file is recreated by the project wizard whenever the MCU is
* changed and should not be edited by hand
*/
/* Include the derivative-specific header file */

To adapt the driver software for a different OLED display, modify the initialization routine. This is
currently limited to only 4 bpp displays. Different color resolutions require further adaptations.
In the OLED.H file, a define, based on the manufacturer part number (for example,
OS128064PK27MY0B00), is used to select which display is connected. A second definition
_UP_SIDE_DOWN allows to select the display orientation.

Image format and BMP2C.EXE Utility
The BMP2C.EXE utility (freeware from Freescale) is a command-line tool to convert a Windows bitmap
file (*.bmp) to a C-language structure used with the OLED driver software. To convert a bitmap file, open
a command window and run the BMP2C.EXE, as described below:
Usage:
BMP2C.exe bmpfile outfile
bmpfile bitmap file to be converted
outfile output "C" file created

Freescale Semiconductor 27

Font Format
The tool converts bitmap pixel from the RGB format to the 4 bpp format using the following equation:
R, G, B are the 8bit values representing the red, green, and blue portion of the pixel.
All converted pixel are packed into a C-language structure (byte array).
Each byte contains the information for two pixels.
28
const char Image[] = {
128,40, // first two byte are size in pixel (x * y)
0x00, 0x00, .........}; // pixel data
NOTE
The software and the BMP2C.EXE requires that the source bitmap file
horizontal resolution is an even number.
This structure can be included into the IMAGE.C source file (for example, in the CodeWarrior IDE).
6 Font Format
Pixel
Bitmap type fonts are stored in a format where one bit represents one pixel of information — monochrome
font. Each letter can then be displayed in one of 16 gray levels.
To explain how the font data is represented, the character 1 is used as an example.
For the 5x7 font, five bytes are used to store each character:
const char FONT5X7 [][5] = {
....................
{ 0x00, 0x42, 0x7F, 0x40, 0x00 }, // 1

7 Conclusion
OLED Display Driver for the HCS08 Family, Rev. 0
Conclusion
The provided documentation and software show how to control an OLED display with an HCS08
microcontroller, even with a limited amount of memory or GPIOs. The software can be used as the basis
for other projects and further enhancements, such as:
• Support for monochrome (1bpp) OLED displays
• Support for full-color OLED displays
• Support for software SPI or parallel interface
• Scalable fonts
• Use of power-down sequence (controlled shut down)
• Implementation of a screen saver
• Power-consumption optimization
• Implementation of drawing functions, for example, lines, rectangulars, etc.(requires sufficient
amount of RAM memory)
• Use of compressed storage of data to enhance memory efficiency
• Utility to generate fonts
More information on how to use an OLED in a real-world application can be found on the OSRAM Pictiva
website (see Section 8, “References”).
For more information on CodeWarrior tools, see Section 8, “References”.
To get to a small memory footprint, some specific actions were incorporated (the storage of the Freescale
Logo image). Only the logo itself was stored and not the surrounding background. Like this the size of the
bitmap could be reduced by 37.5% from 4096 bytes (128 x 64 x 4 Bit) to 2560 bytes (128 x 40 x 4 Bit).
A second method used for the push buttons (Figure 11) is the ability to “darken” a bitmap during runtime
when it is drawn (OLED_DrawImage function — see Table 9). Like this, the storage of two
images—button released and button pressed—can be reduced to only one image. This saves 258 bytes
(50% reduction).
Table 10 summarizes the memory consumption for the example applications. This differences are mainly
caused by demonstration functionalities.
