1.7.48 SD_PUT_ICON
Description: Displays an icon with its upper-­‐left corner positioned at the Current Position.
The icon is read from the file on the SD Flash card attached to the SD/MMC
interface. Supported file systems : FAT12, FAT16, FAT32
Supported formats : .ezp and 24-­‐bit .bmp
Code: 70 hex, 112 dec
Notes: SD card has to be formatted in the supported file system.
About the File Path:
·∙ File Path specifies the full path to the file on SD including directory, filename and extension
·∙ Directories should be separated by: / ( not by: \ like in Windows and DOS).
·∙ File Path is not case-­‐sensitive. The drive and root directory do not have to be indicated, for
example, both: A:/Cat/Jumped/Over.txt and cat/jumped/over.TXT specify the same file.
·∙ Long file names are supported, however the File Path (directory + filename + extension +
NULL) may not exceed 64 bytes.
Supported Formats:
Both .ezp and 24-­‐bit .bmp can be displayed, however it is strongly recommended to use .ezp
files since they can be displayed much faster than .bmp. For example: 320x234 .bmp file is
displayed in 260ms, while the identical .ezp file is displayed in only 90ms.
About the .ezp files:
The .ezp files contain pre-­‐processed bitmaps. They are displayed much faster than .bmp files.
Also, the .ezp files support transparency. The .bmp files can be converted to .ezp files by the
newest version of the ezLCD004flash utility, which supports both individual and batch
conversions.
