I have a ploblem: display png image file.
compile: keil for arm v4.60
MCU LPC1850
emWin version : 5.12 lib (no source code)
pnglib download from www.segger.com/link/emwin_png.zip
but it cannt pass compiling. the error message:
.\obj\lpc18xx.axf: Error: L6218E: Undefined symbol LCD_DrawBitmap (referred from gui_png.o).
.\obj\lpc18xx.axf: Error: L6218E: Undefined symbol abort (referred from pngread.o).
all pnglib package for emwin 4.18/5.00/5.18 have many errors as above when compiling.
the emwinv5.18 lib from LPCWARE(NXP MCU) with the pnglib 5.18 still can not pass compiling.
the specification about png format image is too simple, Could you tell me the method and steps.
Thank you !
