I might have screwed up again... 
It was in the middle of the night and I was sleep depraved, while buying a Duinomite eMega and MOD-IO, I was about $10 away from getting free shipment, so I added a MOD-LCD3310 to the order. Now I have it here, but the problem is that I have no idea what so ever how to use it on my DuinoMite Mega and/or eMega, or if it is even possible. Saw a thread about another monochrome but char based Nokia display (3110 or was it 5110?), but that display seems very different to mine, the 3310 is pixel based i think. A nudge in the right direction is most appreciated. :) 2 x DuinoMite Mega 1 x DuinoMite eMega |

So far I have discovered that if it's plugged in to the UEXT (the way it's supposed to plug in) the DuinoMite becomes very unhappy when one tries to load from the SD card, it just shuts down. :| edit: So I read now that the screens on Nokia 3310 and Nokia 5110 are infact the same screens. This means jman has done this on a Maximite according to this tread. Only problem is that the pins that he list does not compare to the pins that i have. He list the following setup: Maximite Pin Nokia LCD
Pin 1 Pin3(SCE) Pin 2 SPI TX Pin6(DN/MOSI) Pin 3 SPI CLK Pin7(SCLK) Pin 4 Pin4(RST) Pin 5 Pin5(D\C) Pin 6 SPI RX Unused The pins on the MOD-LCD3310 is according to the PDF documet for the older revision on this page called: [code]1: 3.3V 2: Ground 3: 4: 5: #LCD RES 6: #LCD D/#C 7: 8: MOSI 9: SCK 10: #CS[/code] Pin 1, 2 and 8 seems like obvious. Then I can only guess.. Question if: [code]#LCD RES = RST #LCD D/#C = D\C #CS = SCE[/code] 2 x DuinoMite Mega 1 x DuinoMite eMega |

Hi Here you go you can work it out from here Mod-LCD3310 
Hope this helps Jman |

Hello Maria, you're right with: #LCD RES = RST #LCD D/#C = D\C #CS = SCE I connected my 5510 AND 3310 Displays successfully on my Duinomite with seven wires on the Arduino connector (but all pins are also available on the GPIO Port): SetPin 1, 8 'Digital Output for SPI Enable / Analog CON2 A0 SetPin 17,2 'Digital Input for SPI In / Dummy-Pin: Display has no MISO! SetPin 2, 8 'Digital Output for SPI Out / Analog CON2 A1 SetPin 3, 8 'Digital Input for SPI Clk / Analog CON2 A2 SetPin 15,8 'D/C / Digital CON4 D4 SetPin 4, 8 'Reset# / Analog CON2 A3 'VCC / Power CON1 3V3 'GND / Power CON1 GND Frank |

Thank you guys, I now have it running, had to convert my DuinoMite Mega into a Maximite and to test your code jman. :) Two problems is however apparent. 1) Text does not fit vertically on screen (top and bottom line is cut off), the 3310-screen is smaller than the 5110 screen? edit: I now see that it's the vertical offset that is off rather than the screen height, top half of the first text line appears at the very bottom. 2) The screen is very dim - no back light? edit 2: managed to find out how to increase the constrast. Added photo, this is how the text appears on the screen:

Well... After pulling my hair all day and night, the problem is no more. :) seems there is different (at least two) drivers on those screens, and also that the driver is for screens that are 102x67 in resolution, and all that space is writeable. Solution is to shift the display up 5 pixels and start writhing at row 1 instead of row 0. Found out about it all on this old forum post: Nokia 3310 LCD shows only 5 rows of byte-wide pixels After reading the initializing code in C on page two i added the instructions to the screen that was missing and awesomeness was instant. :) Thanks very, very much for the code example jman. :) edit: Forgot... Maybe I should share the altered init part of jmans code. [code]LCD_Init: ' Increased the pauses, better safe than sorry, only occurs once anyway. Pin(RST) = 0 : Pause 200 : Pin(RST) = 1 Pause 200 : Pin(DC) = 0 : Pause 200 ' RESET LCD LcdData= &H21 : GoSub LCD_ByteOut ' LCD EXTENDED COMMANDS Pause 40 LcdData= &He4 : GoSub LCD_ByteOut ' Large VOP Extended Displays Pause 40 LcdData= &H45 : GoSub LCD_ByteOut ' Y-Offset +5 pixels Pause 40 LcdData= &He0 : GoSub LCD_ByteOut ' SET LCD Vop (CONTRAST) Pause 40 LcdData= &H06 : GoSub LCD_ByteOut ' SET TEMP COEFFICENT Pause 40 LcdData= &H13 : GoSub LCD_ByteOut ' LCD BIAS MODE Pause 40 LcdData= &H20 : GoSub LCD_ByteOut ' LCD STANDARD COMMANDS Pause 40 LcdData= &H09 : GoSub LCD_ByteOut ' All on (black) Pause 750 ' Needs to be so high LcdData= &H08 : GoSub LCD_ByteOut ' Display blank Pause 50 LcdData= &H0C : GoSub LCD_ByteOut ' LCD IN NORMAL MODE Pause 40 Return[/code] As far as I know this script will mess up the y-alignment on screens that worked perfectly with jmans original code. 2 x DuinoMite Mega 1 x DuinoMite eMega |

Great news Glad you got it going and thanks for sharing Maybe we should add some defines for the different screen types ? Regards Jman |

Thanks! :) Yea, good idea, but i don't know how to... The strange thing about the different screens is that any 3310 screen work on any 3310 Nokia phone, despite differences, therefore there must either be a universal way of initializing them or a way to tell them apart by probing signals at runtime, or something like that... But I know way to little about these things to even begin to understand what's going on... Yesterday when I was trying to get the screen to align right myself (before i found the tread I link to above) I was sending random commands to the screen in desperation just in the vain hope that I would stumble on something. I then noticed that sending &H28 as last command in the init makes the screen output upside-down, that might be useful if one wants to project the screen at a tilted glass... I really think we should create a Maximite/DuinoMite software repository and hardware database... A place dedicated totally for just Maximite/DuinoMite code and also peoples documentation on how to get certain hardware working with it. I'm not talking about a discussion place, this place is awesome, but strictly a repository and a database. Any other Maximite/DuinoMite users that feel that's a good idea and would consider sharing their non-secret, non-copyrighted codes and hardware solutions to such place? 2 x DuinoMite Mega 1 x DuinoMite eMega |

so you made your duinomite into a maximite or is this now also working with a duinomite? |

I converted it to Maximite because jman's code lacked row numbers an I was to lazy to convert the code to line numbers, but if you convert jman's code to line numbers think it should work well with a DuinoMite. edit: Flashed it with MMBasic 4.0... 2 x DuinoMite Mega 1 x DuinoMite eMega |
