I am using a graphics LCD manufactured by POWER LIGHT i.e,PL G 19264(1A series) Actually when reading data from the data RAM of the LCD,if I read only once from the LCD,it gives erroneous results.But if I read the same data twice consecutively,I am getting the desired result. I am totally unable to understand it needs reading twice though there is nothing written in the datasheet of the LCD.
Please help,urgently!!!
