Please find attached a version of the Armmite software that will work on the STM32H767ZI. 2019-02-03_235354_ArmmiteF7.zip This was done as a one-off to look at the portability of code on the STM32 range. I will not be maintaining this version going forward but if you happen to have a Nucleo-H767 then you can use this firmware on it. The firmware uses an internal RC oscillator so can run on the Nucleo with the ST-LINK board detached. Performance is basically equivalent to a MMX at 252MHz. The port is fully compatible with the Armmite H7 backpack. Use the Armmite H7 manual for details of the port subject to the changes identified below: MM.DEVICE$ gives "ARMmite F7" SPI-CLK on pin 128 and not 126 SETPIN 93,CIN and SETPIN 93,FIN ' not available SETPIN n, AIN [,bits] ' bits limited to 8,10, and 12 PIN(DACn) ' not available PIN(TEMP) ' not available PIN(SREF) ' not available OPTION USBKEYBOARD ' not available OPTION FLASHPAGES n ' n can be 1 (default) or 2 giving 256Kb or 512Kb of program space OPTION LCDPANEL SSD1963_n_BUFF, orientation ' not available OPTION LCDPANEL SSD1963_n_640, orientation ' not available CAMERA command ' not available MOVEMENT function ' not available |

Any chance this should be Nucleo-F767 etc i.e. H767 -> F767? John |

Thank you for this port to the Nucleo-F series. What I would really like to see, and would undertake myself if you are willing to share this code, is a port to the NUCLEO-F446RE--64 pins, 512KB flash, 180MHz. That part seems to me to fill an important slot in the Micromite lineup--an inexpensive ($14.90US at Digikey) 64-pin PCB with the easy access of the ST-LINK connection and enough speed and flash to support gui features. I know there would be a good many differences from the 144-pin version, but I'm willing to try a port.

Can't wait to try this on my board. Thank you for taking the time to even try this port of your code. I can easily live with this being the only update. |

H7 source is available through MMBasic.com. I personally can't see any reason to support STMF4 as there is no significant advantage over MM+ and MMX whereas H7 is MUCH faster and L4 is low power so both bring things the PIC versions can't supply |

I'd love to see a 64-pin Nucleo board in the H series, and agree that it would make F-series ports superfluous, but as far as I can tell the H-series has only the 144 pinner. So a custom design with display would take the Nucleo-H board, the display backpack, and a custom design. That's about 140 solder points for the H board, another 140 + components for the display backpack, and another 140 (more or less) plus components and other connectors for the custom board--so probably well in excess of 500 solder points. That may be nothing for many of you, but for this software person, it's daunting. I'll be happy to try the new port, but didn't bring my F767ZI board when I snowbirded south for the winter, so I won't be able to try it before April.

If you want to try it, quite cheap to buy another :) John |

Is there any chance this will support an external keyboard so it is not tied to a terminal ? Any kind of keyboard will do. If not , I will find a keyboard to serial converter of some kind , maybe arduino or other small board. It runs great and I am happy as I can be to use this board I ordered wrong during the H7 software release. I just jumped the gun before reading it all the way , kinda my MO. LOL |

Sorry, but this really is a one-off release. Implementing USB is always a biggish task so not something I want to tackle on the F7 which I won't be supporting as a long term platform. |

@gadgetjack As somebody mentioned in a response in another thread a couple of months back, Silicon Chip ran an article on a keyboard and/or mouse serial converter in its February issue. I happened to read that article last night in my catch-up magazine reading after being away for several months. PIC32MX270 based, PCB etc available from the magazine. Should be usable in your application. Bill |

I understand not wanting to add the usb to this release , i really do. I will come up with a small micro circuit that will give me the serial input the board needs. Bill7300 suggested a good one and I believe Geoff had a small board that would work ok too. I will go that route. Again , I thank you for writing this one for us. I love to see what you come up with every day when I get on the board. ALl you guys are great to follow. Jack |

That was probably my post on the Silicon Chip keyboard and/or mouse serial converter. I built the mouse version only and it works well with the maximite. The only difference between the two versions is the firmware. I expect that the keyboard version would do what you want. A cut down version of Geoff's ASCII Video Terminal may also do what you want - I think that's the board you are thinking of. That is described on his web site and in more detail in Silicon Chip February 2014. Other members have ported MMBasic to the PIC32MX270 see here. You could use this to roll your own. Bill Keep safe. Live long and prosper. |

I did a tidy up of the H7 code and the F7 variant and put a lot of conditional compilation in so that as much of the source as possible could be common. This means that I have done an update to the F7 despite my earlier protestations. It now has all the recent H7 functionality like polygons, turtle graphics, etc. 2019-04-02_202937_ArmmiteF7.zip Use the H7 manual for details: 2019-04-02_203055_Armmite_H7_Manual.pdf Differences as before: MM.DEVICE$ gives "ARMmite F7" SPI-CLK on pin 128 and not 126 SETPIN 93,CIN and SETPIN 93,FIN ' not available SETPIN n, AIN [,bits] ' bits limited to 8,10, and 12 PIN(DACn) ' not available PIN(TEMP) ' not available PIN(SREF) ' not available OPTION USBKEYBOARD ' not available OPTION FLASHPAGES n ' n can be 1 (default) or 2 giving 256Kb or 512Kb of program space OPTION LCDPANEL SSD1963_n_BUFF, orientation ' not available OPTION LCDPANEL SSD1963_n_640, orientation ' not available CAMERA command ' not available MOVEMENT function ' not available |
