I have a problem with the initialization of the display AGG240128A05-FHW-R

I do not know what could be wrong. Maybe someone has an idea? code:

 &sharpinclude ''GLCD_240x128.h''

Hi there

  do you by any chance have your complete code for the lcd uc1608 spi s8 (i am interested in viewing the way you write to the lcd) thank you
