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. Table 1 briefly describes the OLED pin functions for the serial interface.

1.1 Basic Operation 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.

Address
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.
1.2 Command Description Table 3 briefly explains the available commands (for the serial interface) and their corresponding parameters. For a more detailed description, consult the OSRAM Pictiva or SSD0323 documentation (Section 8, “References,” on page 32). Most commands are used to parametrize the COG for a specific display under specific ambient conditions. Recommendations for setup for various displays are provided by the display manufacturers (for OSRAM OLED see Table 4).

0 0x15 Set Column Address 3 bytes This command specifies column start address and end address of 0 A[5:0] the display data RAM. It also sets the column address pointer to 0 B[5:0] column start address. Second byte A[5:0] sets the column start address from 0–63. POR = 0. Third byte B[5:0] sets the column end address from 0–63, POR = 63 0 0x75 Set Row Address 3 bytes This command specifies row start address and end address of the 0 A[5:0] display data RAM. It also sets the row address pointer to row start 0 B[5:0] address. Second byte A[5:0] sets the row start address from 0–79, POR= 0. Third byte B[5:0] sets the row end address from 0–79, POR = 79 0 0x81 Set Contrast Control Register 2 bytes This command is to set contrast setting of the display. The COG 0 A[6:0] chip has 128 contrast steps from 0x00 to 0x7F. The segment output current increases linearly with the increase of contrast step. Second byte A[6:0] sets the contrast in 128 steps. Contrast increases as level increases. POR = 0x40. 0 0x84–0x86 Set Current Range 1 byte This command is used to select quarter range or half range or full range current mode. With the same contrast level, quarter range mode gives a quarter of the current output of the full range mode. Similar to half-range current mode, it gives a half of the current output of the full-range mode. 0x84 = Quarter-current range (POR) 0x85 = Half-current range 0x86 = Full-current range

0 0xA0 Set Re-map 2 bytes This command changes the mapping between the display data 0 A[6:0] 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.

0 0xA2 Set Display Offset 2 bytes This command is to set the display-offset register to determine the 0 A[6:0] 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. POR = 0. 0 0xA4–0xA7 Set Display Mode 1 byte This command is used to set normal display, entire display on, entire display off, and inverse display.
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 0 0xA8 Set Multiplex Ratio 2 bytes This command sets multiplex ratio N from 16 to 80. 0 A[6:0] Second byte A[6:0] determines multiplex ration N.

0 0xBF Set Segment Low 2 bytes This command is used to set segment low voltage (VSL). The 0 A[3:0] Voltage (VSL) 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 VSS A[3:0] = 1110 (POR) (When VDD > 2.5 V) 0 0xBE Set VCOMH Voltage 2 bytes This command is used to set VCOMH voltage level. 0 A[5:0] 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) 0 0xBC Set Pre-charge Voltage 2 bytes This command is used to set the pre-charge voltage level. 0 A[7:0] 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) 0 0xB1 Set Phase Length 2 bytes This command sets the phase length. The lower nibble of the 0 A[7:0] 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 0 0xB2 Set Row Period 2 bytes This command is used to set the row period. It is defined by 0 A[7:0] 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)

It is defined by dividing the oscillator frequency by Frequency 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.

2.1 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 VCC.

The driver project was developed with the CodeWarrior for HC08 V5.1 — Special Edition development tool. Application features: • Serial interface to OLED display using SPI module (low number of I/Os used) • Low-level routines: — Send data byte — Send command byte — OLED power voltage ON/OFF — OLED hardware reset • High-level routines: — Display initialization — Set drawing area — Fill drawing area — Draw text using bitmap font — Draw bitmap graphic • Two bitmap type fonts 5x7 and 8x15 pixel size are included • Adaptable for other OLED displays or MCUs To open the OLED driver demo project, open file OLEDDemo.mcp in the CodeWarrior integrated development environment (IDE). Figure 7 shows the project view.

OLED Display Driver for the HCS08 Family, Rev. 0 Freescale Semiconductor 17 Software and CodeWarrior‘ Development Tool 3.1 OLED Driver Software Description The OLED driver project contains the following files: Table 8. OLED Driver Files
Files Description
OLED.H OLED driver header file — Constants (defines) for OLED commands — Preparation for different OLED displays — Definition of MCU hardware interface OLED.C OLED driver c file — OLED initialization sequence (array) — OLED functions (Table 9) FONT.H Font include file FONT.C Font c file — Definition of two fonts 5x7pixel and 8x16pixel IMAGES.H Image include file IMAGES.C Image c file — Example images DERIVATIVE.H Header file to include the derivative specific header file — This and the MCU derivative-specific files (for example, MC9S08QG8.H and MC9S08QG8.C) are controlled by the CodeWarrior IDE (Section 3.1.1, “Driver Configuration”). MYTYPES.H Type definitions MAIN.C Shows an example implementation of the OLED driver
3.1.1 Driver Configuration 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.

Figure 9. Select MCU Derivative and Debugger Connection 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 */ #include

And now, the project contains the MC9S08QG.C and MC9S08QG8.H files:
Figure 10. IDE Updates MCU Derivative Files The MC9S08QG8.H file defines a macro with the derivative name, for example, _MC9S08QG8_H, which is used to implement the hardware interface-specific code.

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.
// ------// macros for display selection and orientation // ------// select which display to use, if necessary add new display and init sequence //#define OS128064PK27MY0B00 #define OS128064PK16MY0A01

5 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
OLED Display Driver for the HCS08 Family, Rev. 0 Freescale Semiconductor 27 Font Format
The tool converts bitmap pixel from the RGB format to the 4 bpp format using the following equation: RGB++ Pixel = ------316⋅
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).
const char Image[] = { 128,40, // first two byte are size in pixel (x * y) 0x00, 0x00, ...... }; // pixel data
Each byte contains the information for two pixels. 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 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 ...... }

OLED Display Driver for the HCS08 Family, Rev. 0 30 Freescale Semiconductor Conclusion 7Conclusion 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. Table 10. Memory Consumption Overview
