| Problem with LCD NOKIA 6610 and 16F87X |

hi I'm working with a Nokia 128x128 LCD and a PIC16F876A but I do not know if the screen controller is EPSON or PHILIPS ... this is the sample code I'm using but when I turn on the circuit, the screen lights (LEDs light), but remains the panel LCD black ... what is the problem? here's the code:
| Code: | //// Russell Evolutions Inc.
//// Nokia 6100 LCD with Epson S1D15G10 Controller
//// sample initialization program for PIC16LF872 in CCS C 3-14-07
////
//// Based on Spark Fun Electronics Code by Owen Osborn 1-22-05
//// with thanks to David Carne of SFE for DISCTL help
//// and user 'Ttelmah' from CCS C forum for SSPEN bit idea for 9-bit hardware SPI

You got that code from this thread:
http://www.ccsinfo.com/forum/viewtopic.php?t=37345
But that code is buggy. It's newbie code.
Picoholic provided a link to a Zip file of Nokia code on the Sparkfun
website (nokial6100_ccs_c.zip). Look for the link on that thread.
The Sparkfun code uses the hardware SPI pins, C3, C4, and C5.
The newbie that you copied has screwed up all those pins and
put them on Port D. There's no hardware SPI on Port D.
But then, you have continued this error by moving the pins
to a bunch of other non-hardware SPI pins.

#define LCD_RESET PIN_C6
#define LCD_CS PIN_B0
#define SPI_CLK PIN_B1
#define SPI_DI PIN_C4 //unused
#define SPI_DO PIN_C7

My advice is, go back to the original Sparkfun code. I don't know if it
works, but at least it's using the real hardware pins. |

} |
but the result is always the same ... maybe a Philips controller? Where can I find some examples ready just as a test for the Philips controller? |
