Lcd companion boards support (VKLCD50RTA & VKLCD70RT)

What is this ?

This is a demo program using Renesas RGA library & USB Camera to demonstrate VK-RZ/A1H's companion boards workability.

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 )

tvendov 0:6435b67ad23c 58 *
tvendov 0:6435b67ad23c 59 * This allows programs to read and write files on the same disk drive that is used to program the
tvendov 0:6435b67ad23c 60 * mbed Microcontroller. Once created, the standard C file access functions are used to open,
tvendov 0:6435b67ad23c 61 * read and write files.

tvendov 0:6435b67ad23c 64 *
tvendov 0:6435b67ad23c 65 * Example:
tvendov 0:6435b67ad23c 66 * @code
tvendov 0:6435b67ad23c 67 * #include "mbed.h"
tvendov 0:6435b67ad23c 68 *

tvendov 0:6435b67ad23c 86 * @note
tvendov 0:6435b67ad23c 87 * If the microcontroller program makes an access to the local drive, it will be marked as "removed"
tvendov 0:6435b67ad23c 88 * on the Host computer. This means it is no longer accessible from the Host Computer.
tvendov 0:6435b67ad23c 89 *
tvendov 0:6435b67ad23c 90 * The drive will only re-appear when the microcontroller program exists. Note that if the program does
tvendov 0:6435b67ad23c 91 * not exit, you will need to hold down reset on the mbed Microcontroller to be able to see the drive again!
