| Flexible 4x20 LCD Driver and CCS C TCP IP Stack |
 Posted: Wed Jun 13, 2012 9:07 am |

Hi! How to use properly the flexible 4x20 lcd driver and ccs c tcp ip stack together?
I tried to use it together but the lcd display don't respond.
I'm using PIC18F4620, and I connect the RS, RW, E, D4-D7 to port D of PIC18F4620.
I also tried to use the dlcd.c and it works, but it works only for 2 x 20 / 2x16 lcd.
What modification do I need to make the dlcd.c for 4x20 type lcd? |

dlcd.c is on pudn, and it's simply the traditional old CCS driver, called lcd.c
which he has renamed.
CCS has a 4x20 driver based on the same code, and it's in this location:

Hi! I already solve my problem regarding TCP IP and Flexible LCD
i just comment the #use fast_io(D) in hardware.h so that i can use the flexible lcd driver
my problem now is how to use FAT MMC/SD Card in TCP IP Stack
I tried to use the example (ex_st_webserver2.c) but it's not working
and I also tried to modify it and but it still not working, i can't connect to ftp, sd card is not activating
btw. I'm using Proteus ISIS to test program using TCP IP Stack in PIC18F4620
Is there any example in how to use TCP IP Stack and MMC/SD Card that are easy to understand?
TIA |
