Hi dear friends.
I'm reading this post
http://ccsinfo.com/forum/viewtopic.php?t=26461&highlight=nokia+6100
so i was thinking to give a try with some cheap nokia 6100 clone (sparkfun).
Does anyone knows how to connect such LCD to 16F877 ?
Can i convert the code for use with 16F877 ? |

The page on the Sparkfun site has lots of links to documents and code examples, even example code for a PIC16F87x written in CCS-C.
I've never seen an Electronics site with so much practical product info. What more do you want??? They even provide code for your processor!

I don't know you can do it.  |

I know i can't 
I didn't buy this lcd yet because i got some old ones from nokia 3200.
I pull them out.
My problem is more on hardware side - for now :-).
There are few examples with picmicro and 6100 but I can't find some "how to connect" tutorial for 3200 LCD. I found pinouts but heeeee ?
| Code: |
2 Gnd
3 MBus
4 Vpp
7 FBus Rx
8 FBus Tx
A Vbat+
B BSI
C BTemp |
Which pins on 16F877 should I use ? |

OK on the 16f877 side but what about LCD side ?
What pins of the LCD should i use, what is what.
Thank you for your help!.
LCD_RESET PIN_C0
LCD_CS PIN_C1
SPI_CLK PIN_C3
SPI_DI PIN_C4 //unused
SPI_DO PIN_C5
------------------------------------------
2 Gnd
3 MBus

The pinout is at the bottom of the page referenced by the first link you gave
http://www.sparkfun.com/commerce/product_info.php?products_id=569
Pin breakout from source code:
LCD_CS PIN_C1
SPI_CLK PIN_C3
SPI_DI PIN_C4 //unused (means you don't connect this one)
SPI_DO PIN_C5
From Sparkfun Pinout List:
1. VCC-Digital (3.3V)
2. RESET -------> LCD_RESET PIN_C0
3. SDATA -------> SPI_DO PIN_C5
4. SCK ----------> SPI_CLK PIN_C3
5. CS ------------> LCD_CS PIN_C1
6. VCC-Display (3.3V)
7. N/C
8. GND
9. LED GND
10. LED V+ (6-7V)
Looks pretty straightforward to me. |

Thank you dyeatman but i didn't buy this LCD yet.
Instead of this i found some old LCD's from cellular phones ( to save the environment :-) )
Sony ericsson t290
Sony ericsson t100
Nokia 3200
The pinouts that i posted are from nokia 3200.
2 Gnd
3 MBus ---
4 Vpp ---
7 FBus Rx ---
8 FBus Tx ---
A Vbat+
B BSI ---
C BTemp ---
I dont know what is FBus RX and TX, BSI, BTemp.
In cca 2 hours i will send photos and pinouts of other two model's, so please be so kind and help me out. |

What you are lisiting is the pinout of the phone not the LCD.
- aaaaaaaa, damn.
OK, i gonna try to connect it and see what will happen :-)
Thank you for your reply's ! |

Sorry, one more thing.
Do you know if there is some compatibile CCS driver for sony ericcson T100 LCD. I search for on the forum but whitout succes.
I am going to search for hardware connection.
Thank you. |

| stuck, NOKIA 6100 knock off LCD to PIC18F4580 |

Can anyone help?
I just purchased a nokia 6100 lcd last week from sparkfun and have modified code for my 18f4580 chipset, I have modified from the example provided with lcd breakaway board Marcus Russell wrote.
After modifiy code I have been abler been troubleshooting for several days now with no luck. All I have is a the backlight working with blue screen and I have verified that the clock signal from my pic looks correct.
Could someone take a look at my code to see if I am missing something?
I know its alot to ask.....
Also I have verified that the driver/controller is an EPSON S1D15G10

Download the 18F4580 data sheet:
http://ww1.microchip.com/downloads/en/DeviceDoc/39637c.pdf
Look at this page on page 80 in the Acrobat Reader. It shows that
the SSPEN bit is in the SSPCON1 register.
| Quote: | | TABLE 5-2: REGISTER FILE SUMMARY (PIC18F2480/2580/4480/4580) (CONTINUED) |
Now look at this table on page 73 of the data sheet in the Acrobat reader.
What is the address of the SSPCON1 register for the 18F4580 ?
Find the correct address and modify the value shown in bold above.

| Nokia 6100 LCD |
| Posted: Thu Jan 27, 2011 12:29 pm |

I'll try to interface the Nokia 6100 LCD to a pic 16F877a by using the CCS C software given at Sparkfun site.
Below are the images of the LCD that I found at a local cell phone spares shop for around 3.5$ each. It has got a green pcb and connecting wires so it should have an Epson controller. But on a page of LCD photos, an LCD similar to mine was listed as having the phillips controller. Is there a way to be sure? or can anyone verify it by its photos? Well I could have compiled the code and tested on the chip and LCD but asking on the forum might save some of my hair from going white I guess. Any help is appreciated. Thanks in advance.
