1 Introduction
This application note describes how to display multi-language fonts on FT800 using an external
character IC. Essentially the character IC provides raw data to allow a bitmap to be created for the
required symbol that the FT800 can display.
1.1 Scope
This document shows how to display multi-language fonts on FT800 using an external character
IC. The character IC - GT32L24A180 was selected for this example introduction. Example code is
shown to explain how to output the multi-language characters on a display.
1.2 Overview
1.2.1
Hardware
The diagram below illustrates the overall hardware setup. The character IC and the FT800 are both
SPI peripherals with independent chip select lines.

2 Introduction the Character IC GT32L24A180
2.1 General
GT32L24A180 contains a 15X16 dot matrix font size, supporting character sets including GB2312
/Unicode simplified Chinese, BIG5/Unicode traditional Chinese, JIS0208/Unicode Japanese,
KSC5601 Korean and 173 countries characters in Unicode. Also supported is the Chinese PINYIN
input method from a PINYIN code list.
The data format is arranged as vertical - byte, horizontal - string. The user may obtain the address
of certain characters dot matrix with the calculation method given by this application note, which
enables the user to access more character data by continually reading from the address already
obtained.

Calculation of Character Address
GB2312 24*24 dot matrix GB2312 Font was selected for this example.
2.2.3.1 Parameter Declaration
GBCode indicates Chinese characters code.
MSB indicates GBCode’s high 8 bits.
LSB indicates GBCode’s low 8 bits.
Address indicates Chinese characters or ASCII character dot matrix address byte in the chip.
2.2.3.2 Calculation Method
HZ2424ZF_ADDR = 0X100000;
HZ2424HZ_ADDR = 0X104F50;
// Full width symbols, used to support the character，282 Bytes
if(MSB >=0xA1 && MSB <= 0xA3 && LSB >=0xa1 )
{
temp = (MSB - 0xA1) * 94 + (LSB - 0xA1);
Address = temp *72 + HZ2424ZF_ADDR;
}
// Chinese characters 6763 Bytes
else if(MSB >=0xb0 && MSB <= 0xf7 && LSB >=0xa1)
{
temp= (MSB - 0xB0) * 94 + (LSB - 0xA1);
Address = temp*72 + HZ2424HZ_ADDR;

3 Example Application Code
For the user’s easy understanding, this example application will show Chinese character “高” on
FT800, using FT800_SampleApp_1.0 as base.
a.
Get the input character’s coding. Using GB2312 as example, with the Chinese character “高” in
GB2312 code, its HEX code is MSB: 24+0xA0, LSB: 63+0xA0
b.
The character IC provides its own calculation between character Hex value and the chip’s
related dot matrix contact storage address, with the IC GT32L24A180, the address in the chip
is: 0x113440
c.
Following the GT32L24A180 reading instruction, read the bytes out from the chip, the length
should be: 24x24(3bytes*24=72bytes)
Figure 3-1: 24*24 dot Chinese characters arrangement
d.
The content should be displayed as a bitmap in the FT800 in L1 format:
Figure 3-2: L1 format layout
Each ON (‘1’) bit represents a characters related color dot, each off (‘0’) bit represents the
background color, the other parts are don’t care.
e.
Put the “高” dot matrix contents in Src/SampleApp_RawData.c (The array mechanism is
chosen for easy teaching, a user may choose alternative coding styles e.g. read binary from
file, reading from flash program space, and store the binary data into a buffer malloced, then

};
g.
Modify SAMAPP_GPU_BitmapFont() in Src/SampleApp.c:
Create an extern definition of gao[] in SampleApp.c: extern unsigned char gao[];
Change the SAMAPP_Bitmap_RawData_Header index to 3;
Replace the “SAMAPP_Bitmap_RawData” in SAMAPP_GPU_Bitmap() by “gao”
Reference sample code below:
ft_void_t SAMAPP_GPU_BitmapFont()
