How to Configure ?

You can choose which display is installed by altering the lcd_panel.h file

Leave the active one & comment out the others:

#define     LCD_VDC5_CH0_PANEL                  LCD_CH0_PANEL_VKLCD50RTA
//#define     LCD_VDC5_CH0_PANEL                  LCD_CH0_PANEL_VKLCD70RT

You can alter the whole demo with your pictures if you like:

How to compile ?

  • The Demo can be compiled in 3 modes:
    • I. Execution from the internal 10-MB on-chip SRAM.
      • After import in the online compiler just leave only the VKRZA1H_RAM.sct & delete all others linker files in the TOOLCHAIN_ARM_STD folder.
      • Save the result binary in the SD Card (<SD>:\vkrza1\lcd_sample ), altering vkrza1h.ini by this way
    • II. Execution from the on-board serial FALSH in dual (32-MB) mode.
      • After import in the online compiler just leave only the VKRZA1H_DOUBLE.sct & delete all others linker files in the TOOLCHAIN_ARM_STD folder.
      • Drag & drop the result binary in MBED disk, (previously inited in double flash mode)
    • III. Execution from the on-board serial FALSH in single (16-MB) mode.
      • After import in the online compiler just leave only the VKRZA1H_SINGLE.sct & delete all others linker files in the TOOLCHAIN_ARM_STD folder.
      • Drag & drop the result binary in MBED disk, (previously inited in single flash mode )
