Just came across this PIC site thgh Google serach. I have worked on SPI Module of PIC18C452 for RS232 communication.<BR>
Can somebody guide me for changing this RS232 code to RS485 code. This is bcoz of change in specs of the distance between the two communicating nodes!!!<BR>

Hello, after attempting several peoples code for driving a Hitachi HD44780 based LCD I am confused. I happen to be using a Optrex which is a 16x2 display. I have this connected via PortD  on a 18F452 Microchip processor. The processor works fine as I have written simple routines to blink LEDs and everything works fine. When I attempt to initialize the LCD and write a few characters, the display lights every pixel in every character position. I know I am doing something, because without the code the display remains totally dark. I have tried assembly routines as well as C routines all with no luck. I am using the C18 C compiler and MPLAB 7.2 with no luck. I have even tried using their XLCD libraries to start from scratch again nothing. Does anyone have any routines that work with the 18FXXX? I would love some recommendations. Can someone please tell me what changes need to be made in .h files to reflect the port/pins. Thanks, Ricky<!-- 38616.8600115741 EOR -->
