By Padmaja MedakaI was working on this(μEZGUI-1788-70WVM-BA) display.
initialization of LCD controller registers,
pin connections assigned,
SDRAM starting address to LCD base address,
finally enabled LCD and backlight.
it show full white color means that light was because of backlight right? after that I was tried to write lines display clear but nothing was done. I changed different pen colors also then also i didn’t get any pixel variation means color change or something.
may i know the reason for this state? Sad
One more thing is Frame buffer address. frame buffer address is LCD base address or local sram memory location ??
in put_pixel function i used ((win->fb + y * win->xpsize)[x] = color; ) this instruction at that time this win->fb need valid address otherwise it wents to hardfault_handler. How can i rectify this bug?
i was not using emwin, using Normal c code only
if i want to load the default *.bin(which i have at kit brought time) file to this module how can i load means what is the starting address to load flash file which contains SD card accessing code.
thanks & regards,
padmaja
