 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

Prompted by Kermess's issue with the Nokia 5110, I have also updated the loadable SPI driver for the SSD1306 OLED display which would have had the same problem under 5.1. This driver was written for the MM2 but should run on the MM+ using SPI1 rather than SPI2 but this is untested. I have also created a loadable driver for the SSD1306 OLED running on I2C. This will run on either the MM2 or MM+ and incorporates Geoff's bitbang I2C routines so the display can be connected to any two pins (these must have pullup resistors e.g. 10K). The I2C driver should support both the 128x64 screens and also the 96x16 version referenced here (jman, please could you test? just set the size parameter to 2) I2C driver sub mm.startup

Hi Peter [quote] (jman, please could you test? just set the size parameter to 2) [/quote] Sure can and I can confirm this driver works perfectly with SSD1306 OLED running on I2C @ 96x16 Thanks Heaps Jman |

Hi Peter. You can review the display Cfunction KS0108 to uMite V 5.1 My idea is that. I have several displays of this kind and want to give I2C output connection and use them. Thank you. David |

I'm not sure what you are asking for. KS0108 is parallel interface with lots of pins (14). It is also a 5V only device so really need level conversion between it and the Micromite as the data pins switch between inputs and outputs to test the "busy" status There is a working set of code for it here. I don't currently intend to convert this to a loadable driver, the coding isn't too difficult but it takes ages to get it set up and working on the breadboard before you can test anything. |

This is awesome Matherp!!!! Thanks for these, will come in extremely handy. Are the commands to use the I2C version of the 1306 the same as what you had in the earlier driver? Also, if I am using the normal I2C pins on the 28 and 44 pinners, is there anything different or will it just work with those pins also? |
||||
| matherp Guru Joined: 11/12/2012 Location: United KingdomPosts: 10066 |
No: it is a loadable driver and so uses the in-built MM firmware commands BOX, TEXT,RBOX etc. The only thing is that there are only two colours "0" and "anything-else" |

OH!!! That is awesome. Does that mean fonts can work also???? |
||||
| matherp Guru Joined: 11/12/2012 Location: United KingdomPosts: 10066 |
Yes, everything that would work on any other type of display except colour yes, but I can't guarantee if it will co-exist with other I2C devices. better to use other pins |

Matherp, just tried this out using .96" I2C Oled. Alls I can say is... THANK YOU!!!!!!! Now these little displays look AWESOME! What a great CFunction! |

Hi Not sure if this the correct place to post this but as I am using this FINE driver with an I2C OLED I thought this the correct spot to post. I am trying to control the Text command but I am having an issue with the orintation example below x=0:y=0:T$="Hello":o$="L" F1=1:F2=2 Text x,y,T$,O$,F1,F2 ''This one will produce an orientation error Text x,y,T$,L,F1,F2 'This one works as expected Regards Jman |

@jman, The syntax of the TEXT command requires a 'justification parameter' after the string. The justification parameter is, for example, something like CM (for centre, middle). Refer to User Manual for other justification options. So in your first example, you are passing a second string' and hence the error

Correct but I want to pass the justifaction paramter via a string or some other method. I see from the manual these can be 1 or 2 letters as if the second letter is missing then the default will apply (Top) Regards Jman |
||||

I don't believe you can pass it as a string, and if this is the case then you will have to look for another way to achieve whatever you wish to do. If you have the desired justification stored in O$ (or even as a value in a variable), then why not simply use SELECT CASE O$ with each CASE line of code then using the justification parameter in its required format (i.e. just one or two letters that are not in quotes) |

Hi Thats the way I did it :) was hoping there was a tidier method Thanks for the reply Regards Jman |

Hi Peter I have been playing with a 96x16 OLED and noticed a small issue the CLS command does not work. If I start the driver with the screen size option set to 0 then the CLS commands works if I set it to option 2 then the CLS command does not work Any ideas Regards Jman |

As a workround does the following work ?: BOX 0,0,96,16,0,0,0 |

| jman Guru Joined: 12/06/2011 Location: New ZealandPosts: 711 |
Hi Peter Unfortunately not I also noticed that the Box,Rbox and Circle don't work. Rather odd. If I change the display to a 128x64 one this all works but the text is the incorrect size (as we know) Regards Jman |
||||
| matherp Guru Joined: 11/12/2012 Location: United KingdomPosts: 10066 |
Jman This doesn't make any sense as the driver is in two parts. When you call circle it writes to a memory image of the screen which is exactly what text does. The routines are identical irrespective of screen size. Then the actual write is done at the end of the Basic command by a separate routine. Again there is no difference Please could you try different orientations and let me know the result. |

HI With the orientation set to 1 it works I originally had it set to 3 Now the commands work but one odd thing to get a box around the edges I have to use box 0,0,95,15,1 and not box 0,0,96,16,1 with orientations 1 and 2 cls works with 3 and 4 it does not. I did not try all the commands in each orientation but can do if required Hope that helps Many Thanks Jman |

This is a feature in Geoff's code that I have already discussed with him. No need, I understand the issue but I'm not sure I can fix it easily without a display to test with. Can you live with orientations 1 & 2 only? |
