Hi everyone !

after some good results working with the nokia LCD, I decided to wite a routine in order to draw an small histogram in the Nokia´s LCD.
But, after reading the PCD8544´s datasheet, i discovered that the LCD doesn´t have a direct mode wich allow us to draw on it pixel by pixel, and when we need to set a single pixel, we need to know its other 7 neighbour pixels.
Is taht right ?

Do I need to read the memory first and make some logical operation with the bits to draw what I want ?

Have someone developped a routine to draw lines (for example) on this LCD ?

thank tou
