we are trying to drive a sed1335(3.3V) based 320x240 graphic lcd with msp430 family. When we try to write a data which have 7 or 8 ones (like 0xFF, 0xEF,0xDF ....) , the lcd starts to flicker .
How can we resolve this problem?
One tip that come in my mind is , msp430f149 can not supply enough current to sed1335???
I guess you shouldn't really update the data at all unless ur putting new data to be displayed
i worked with a character LCD display before
all it needed was the data once ... and only when u send the new data should u update it .
Try it
We only update the new parts. Actually no need to update, if you read it many times it starts to flicks....
We tried to find the problems for many weeks )
At then end we changed the company and LCD of course there is no problem. Everyting is OK now.
