5.0 Interface
Design
1. Firstly, put all pictures needed into the folder of BMP_FILE, convert them into BMP format and change
picture names in proper sequence from 000.BMP. The operation can be completed with software of ACDSEE;
see
Appendix I
for details in operation.
The picture files with names in proper sequence are shown in figure below:
2. Execute batch processing command MakeDAT.bat and three files will be generated in the folder of
BMP_DATA after execution, among which BMPDATA.BIN is the data file where all picture data are put
successively and TABLE.BIN is the table file equivalent to index file; copy these two files into the folder
virtualized by the module and then they are available for use. There are picture serial numbers and
corresponding information of picture size in the file of BmpDataBin.h, which is a reference provided to user
without the necessity of being copied to USB flash disk.
3. If special character display is required by user,like Chinese or Japanese etc.The software attached in this
module can be used for extracting font library; see
Appendix IV
for details.

Only for Chinese version

Revise the name of extracted font library file and copy it in to USB flash disk for application; the file name
should be changed as HZK.BIN.
4. Note: this USB flash disk is a virtualized one; the file system is regulated for the convenience of application
of this module and improvement of picture refreshing speed; please use FAT12 to format the USB flash disk
(this is the default format in WinXP); the limit number of files in root directory is 16 and generally there are only
font library file, table file and data file; if other files need to be stored by user, it had better to make a new folder
for storage of these files.
5. Press K1 key (reset key) on module after all files are copied into USB flash disk and then they are available
for use.
Note: The display of LCM is turned off When transfer data using USB, The data stored in RAM inside frist, this process is
relatively fast, about 500Kbyte / sec, after which there will be a data dump of the process (speed about 100Kbyte / s), don’t turn
off power, When the data dump is complete, TFT will display
.
6.0 Control
Command
This module adopts alphabetic string to control all operations.
The command format begins with command word continued with parameter list in which parameters are
