Testing an Epson S1D13705

Greetings,

Is there a way I can perform a hardware test on a S1D13705 Epson LCD
Controller. I am currently interfacing the controller with an MSP430,
using various ports to access the Controller, my current test code
isn't working, but there is no way of finding out if the chip, or my
code is at fault. Any help would be appreciated.

Dear Elfred,

the easiest way to check MCU-S1D13705 interface would be rading chip ID 
(offset 0x00 in registers area). Then you can try to drive GPIO pins 
(also using control register). If those work then there is nothing else 
left but setting properly LCD interface registers and see if your 
display works (you may also do it without LCD by probing S1D13705 
display driving signals on the oscilloscope ie.FPFRAME). When attaching 
LCD remember to set up look-up table (LUT) so you can display colors or 
gray shades.

Have fun
