Reg interfacing LCD to using 1.

I will appreciate it a lot if someone can assist me in getting assembly language codes to display characters on the LCD. The is a 40 pin integrated circuit ICdesigned to perform a variety of interface functions in a computer environment. The information was helpful but I didn’t get anything to help me with assembly language programming.

InterfacingLCD and I have attached a proteus illustration of my description and a code which displays some information on the lcd when hard wired, wjth not when simulated in Proteus. All information read from and written to the occurs via these 8 data lines. Distorted Sine output from Transformer 8. InterfacingLCD interfcaing Have just uploaded a zipped file with the proteus file and the assembly codes MODE 2 is a strobed bi-directional bus configuration.

However, initializing it with the introduction of the is my problem now. Some examples and tutorials to get you started: Last edited by bigdogguru; 9th January at InterfacingLCD and However, I do not know how the introduction of the will affect the programming.

I realised that most of woth tutorials use circuits in which the LCD is directly connected to the Microcontroller.
