Hi,
I have just made some basic operations on Epson S1D13706 LCD controller
driving 320x240 TFT display. Everything looks good - programming config
registers, writting and reading display memory, configuring LCD clock,
HSYNC, VSYNC end ENAB signals. However there is one thing: when I
initialize configuration registers,LUT and erase display memory (all
bytes set to 0) LCD displays nothing as it should (display is blank -
color number 0 from 256 palette is 0x00,0x00,0x00). But when I write a
single byte 0x01 (where color 1 is red) to display memory then instead
of lighting just one pixel I can see that the WHOLE COLUMN is displayed.
Why can't I control just one pixel? Has anyone had a problem like mine?
Regards
Daniel
