 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. |

Hi crosstydown, I had no problems configuring and using pin 5 and 6 as digital outputs, it worked fine. But I didn't try anything else. What did you try? Michael |

Hi crosstydown, my version was indeed build for the 32MX695F512L, which is used in the TFT Maximite sold by segor. But I didn't include the bootloader. Therefore you have to upload it using the preinstalled bootloader and not a PIC-Kit or something similar. If I get you right, you uploaded the latest version from heise-github including the bootloader (TFT_Maximite_plus_bootloader_V44B.hex) and discovered afterwards that this version is build for the wrong chip? That's hard luck! Did you upload this version before you tried my version or afterwards? Did you upload my version using the bootloader or a programmer? Unfortunately I can't do any tests at the moment becuase my TFT Maximite is currently unavailble. Maybe next weekend. @ all: Has anybody else tried my version and encountered the same problem with MMBasic Pin 5 and 6? Michael |

Hi crosstydown, you were absolutely right, I had a bug in the version I published. It's even in the short description how to build your own version of MMBasic: The last line is wrong, the #define is commented out. So it has to be: - add "#define FINALBUILD" after the very first "#endif" I'm sorry for this! Unfortunately I can't edit my old posts, so a new hex-file is attached to this post.

No need to shout 
The larger LCD displays have a higher resolution which is why the TFT-MM only supports some 4.3 and 5 inch displays. It would be more complicated to drive a larger display at a reduced resolution that the MM could handle. |

hi greg, the resolution of the 4.3 is ok but the screen is very small for my big finger, it is posible to connect 7" have full screen but with the resolution of the 4.3 ???? |

maybe this one ? :Innolux AT070TN07 V.B |

I don't think it would be compatible, based on comparing the connector pin-out of this display with known compatible displays. While it may be possible to somehow hack a 7 inch display to be driven directly from a TFT-MM at a reduced resolution that the MM can handle, I don't have the experience to do this personally. Greg |

Trying to compile the sources with the new touch routines I got an error message: In External.c line 334 I had to change: item_init[i ]=0;
to: item_active[i ]=0;

Hi JBacker32, You are right, this is an undocumented feature from Carsten. He change the name of the function. I ran into the same problem but forgot to mention it in my short description above. It's only in the detailed description on my blog. Sorry about that. Michael |
