Hi Rudolph,

I was able to turn on the backlight thanks for your help.
As a next step I need to load a screen can you help me in doing that like if there are any small snippet that i can load and check , I have used EVE editor and developed a screen using that tool . It would be helpful if u can provide me with small code snippet or any example.
Are there any steps to be followed to load the bitmap?

Thanks in advance.

Hi ,


I understand I should read REG_ID value till it returns 0x7c in the document , can u provide any example for that, or any known good value to check the working of display.
