DIY自己的MP3的参考价值极高的代码。含有详细的解释

Hi ALL !
This is instruction for making national language support for yampp-7 player
with Color LCD.

Yampp support maximum of 20 national characters definition. Any of it must 
have ascii code above 127. If you don't know these codes, please send to yampp 
any MP3 file named with same national characters, and do "Dump Data Section" 
in yamppLink. You find these codes in songbase sector after dump 
(songbase_start, in my case this is 5th sector).

Next you must prepare file witch codes conversion table, and characters
definitions. For do this i publish an example with Polish language set 
(file "Polish_C.ASM"). First you must setup chars sequence table to define all
avaliable characters in designed language (upper case and lower case characters).
Maximum count of all characters is 20. First char code is for first font,
second for second font ect.
Next you must define apperance for all font. One font have 14 bytes of data 
defined from left to right, line by line (standard 8x14 font format). 
Font sequence must be same as sequence in chars lookup table.

If you ready, you must compile this source by running "Compile.bat" with 
source file name (without extension !!!) eg. "Compile.bat Polish"

Now you may load this file into yampp.

First method using yL:
1. Run yL, go to "Options" -> "Preferences", and set "EE-Prom Start Address ..."
   to 16 .
2. Click "OK" for save and close window. You may do these steps only one time.
3. Connect to yampp.
4. From menu "Actions" choose "Write Arbitrary data from file to EEPROM",
   select file with compiled datas (eg. "POLISH_C.BIN") and accept write.
5. Disconnect yL from yampp

Second method using YLINK program:
1. copy ylink.exe and rdwr.dll from "Graphics" folder to "Lang" folder
2. write:
   ylink -d COM5 put-natchar POLISH_C.BIN
   If your FTDI have com number other than 5, use correct value as ylink -d parameter.

That's ALL.

Enyoy !
