Beta 1 (see this post) contained a serious bug which could cause the Micromite to crash on startup. This has been fixed and Beta 2 is available from here: geoffg.net/Downloads/Micromite/Micromite_4.7_Beta2.zip (this link works) So please skip Beta 1 and go straight to this.

Geoff, as it is with betas, I got stuck after configuring the LCD and touch. OPTION LCDPANEL ILI9341,L,4,5,6 OPTION TOUCH 7,2 
Have I used an incorrect pin? GM PS. GUI TEST DISPLAY still works (and I am impressed with that  ) |

My apologies Graeme (and everyone else who hit this issue). Beta 3 should fix this issue. Download it from here: http://geoffg.net/Downloads/Micromite/Micromite_4.7_Beta3.zip I have a suite of test programs that I run to verify a release but unfortunately they do not cater for various combinations of pin numbers - that requires me to manually plug wires in and run tests. As a result it is hard to cover all combinations. Geoff Geoff Graham - http://geoffg.net |

Thankyou Geoff for your speedy follow up. Looking forward to trialling 4.7B3. It may be cold in the shed at the moment but I have to fire up the PICKIT. GM |

I think the invalid pin is returned if the OPTION LCDPANEL is already initialised. If you issue OPTION LCDPANEL DISABLE you can then issue a new OPTION LCDPANEL ILI... This seems to be case for both beta2 and beta3. Is this a good thing! If the OPTION LCDPANEL is like an AUTOSAVE and has a finite number of cycles before it wears out the memory, then this would prevent you accidentally putting it in a loop and running it many times, maybe a better error.

Thanks again, Geoff! Some Feedback: As far as I can see the b3 runs as expected. 
/* Demo code on 28 pinner (Micks Backpack 170 ). OPTION LCDPANEL ILI9341,L,4,5,6 OPTION TOUCH 7,2 */ Best regards Michael PS It would be great to have some sidescoll (like disco4nows fantastic Battery Monitor ) or BLIT. Maybe in the future ...?  |

Hi Geoff, I am in the process of converting one of my programs that uses Peter's CFunctions. I have been using the touch panel interrupt driven. i,e configured as SETPIN T_IRQ,INTL,readtouch,pullup 'Use interrupt driver touch All the examples I have seen poll the touch screen, but configuring the interrupt works well and you don't need to poll. Could we have: OPTION TOUCH T_CS Pin,T_IRQ Pin [,target] and when target is specified set T_IRQ as an interrupt calling target. If I try to SETPIN on T_IRQ I get a error:Pin in Use. I also SETPIN T_IRQ,OFF 'disable interrupt driven touch when a touch is registered, so nothing else is read until the response is processed and the SETPIN T_IRQ,INTL,readtouch,pullup is issue again. So you can hold you finger down a long as you like and only one touch is read each time it goes low. Probably better, is it just possible to remove the protection on the T_IRQ pin when the OPTION TOUCH is issued so it can be manipulated at your own peril.So you can alter it to have an interrupt target and even disable it temporarily.

Hello I am new on this forum, but I am not terrible in English... I have just installed 4.7 beta 3 ... the instruction " option lcdpanel " seems failing: 
If I remove the instruction " option lcdpanel " it works!! |

@CFLY you cant use option lcdpanel within a program. GM |

Christophe as the message is saying, it is invalid in a program. You can only issue that option from the command line. Not in a program. Bob |

OK thank you, thus, if I want to have an application which runs only, without connection with the pc, after transfer of the program, in command line : " autorun option one " and " option lcdpanel " ... ok, good ... |

"option autorun on" and " option lcdpanel..." ...  |

a couple of quick questions for geoff: why is it that OPTION LCDPANEL ... and OPTION TOUCH ... are implemented such that they can only be issued from the command line and are persistent? this means that a program that uses the panel can not be made fully self-contained within just the program listing. surely it would be just as easy for a program to issue the two commands as the first two lines of basic code? or is there some technical reason for the way it is done? and are there future plans to have the LCD panel work as a substitute for the output side of the console? i've been thinking around the idea of 2 micromites linked together, one running a basic VT100 emulator, driving an LCD panel and charlieplexed keyboard. the other being the 'user' processor. LCD + keyboard + 2 micromites would form something very similar to a pocket computer from the 1980's era, but with more memory and a bigger screen. cheers, rob :-) |

I have just finished my LoRa receiver project, and I was looking at using a better LCD display, the Digole I was using is a bit low contrast. The LCDPANEL therfore seemed quite appealing. However my receiver uses a LoRa device that is SPI and the instructions say as the Micromite II has only one SPI interface, and the LCDPANEL uses it, the SPI is not available for other uses. Its common to share SPI amongst several devices via the normal chip select pin. Is there some specific reason why, if you use LCDPANEL, you cant then use SPI for other stuff ? $50SAT is Silent but probably still working. For information on LoRa visit http://www.loratracker.uk/ |

As the others have said Geoff, my thanks also again for all your time and effort - and also to Peter Mather for his major contribution with the graphics displays. I've just loaded up V1.7 beta3 and it fired up fine. Haven't tried the new MMBasic LCD setup just yet but it still runs yesterday's 2.4" program developed on V1.6B that we were playing with just fine - and not even any pin changes! Greg |

An example of realization with the MkII 28b and MMbasic ver 4.7b3. And 1.8 TFT LCD ( ST7735)... CLS, ROX, tested RBOX and TEXT ... it works well... |

I wonder this, too. Could OPTION x check to see that the new value is the same as the old value and just skip trying to write to flash? So the first time OPTION LCDPANEL ... really does a change to flash, but then the second time it is run it sees that flash is already set to those values and doesn't need to change.

Thanks Geoff and Peter for your efforts. I've tried some of the new features using a non-touch ILI9341 connected to a 28-pin Micromite and they work great.
