Ops, sorry my mistake. I never did update the BOM column's header. Read it this way: |-------|------- |----------|-----------|-------------| |Part | Value | Device | Package | Opt./Man. | ^^^^^^^^^^^ All optional components can be safely omitted from your assembly. They are there only to show full compliance to STM32 uP reference design, but they are mostly redundant for this use. |

No worries, thx for the info. Is there some documentation I can read to understand what some of those header values mean. I think I understand Part and Opt/Man cols . There others I am not 100% sure about and looking to understand how to read BOMs correctly. |

Hi,
-what is the purpose of the 4 digit code that is required? -Is it needed for the device to work? |

The 4-digit code is the unique id code of each board, coming from the unique id code of the STM32 assembled on it. In order to be able to run on any single hardware, each copy of the firmware must be signed/encrypted with a matching code. So, in poor worlds, each firmware copy is 1:1 tied to one and only one board. Quote:

I would name it "anti-unauthorized-clone" protection. I was fed up of seeing so many excellent open sourced retro projects being plundered by vultures out there, making money on other's work cloning stuffs, without any effort or contribution to the original project. So I decided to keep the hw open whereas protecting the firmware from easy cloning. One of the "vultures" I mentioned above once told me that there was no point in my position, as he could write a compatible alternative fw in few hours, so my protection was worthless. I am convinced he was right: an STM platform coding pro would make it witout any doubt in actually few hours, but on the other side, I am still sitting here waiting for that vulture to come out with his own firmware build Last edited by sampedenawa; 11 February 2021 at 07:42. |

Oh and honour the license of the original design. Plenty don't do that, especially when it often means releasing their own files |

Hi sampedenawa,
Just a question: The BOM specifies the LM1117MPX-3.3 voltage regulator, but they're too hard to get at the moment in AUS. Most suppliers say out of stock till next year. Can the LM1117IMP-3.3 be substituted instead since these are much easier to get. Thanks a bunch! P.S. This chip shortage is really making it difficult to get anything at the moment for any of these hobby projects. Can't even get any STM32F105RBT6 until the end of the year at best guess! |

Yes, absolutely, The LM1117IMP-3.3 should be extended temperature range, so you can test your adapter up to -40C
Chip shortage is the same all around the world at the moment. Here in EU is not different; can't find on retail even the simplest chip I can imagine. Should you find alternative STM32F105RCT6 (though I doubt it), they will fit as well. Quote:

Would it be possible to add wheel support such as Rys MKII?

I am developing a rev2 version of the adapter, whit the aim to - reduce the overall size of the pcb - make it compatible with CD32 PAD protocol - make it compatible with mousewheel In addition, I will probably share a little hardware "hack" to modify current Rev1 adapters everyone has got in order to be compatible with newest v2 firmwares and the above features. To be more precise: - at the moment I am waiting a bunch of new v2 pcbs to arrive from the manufacturer - I am working on CD32 PAD protocol (ETA: around XMas or so) - Next I will address mousewheel (which needs an Amiga-side driver counterpart) |

Hi sampedenawa,
I'm about to build 5 HID2AMI's, 3 for me and 2 for a mate. At the moment grabbing any STM32F105RBT6's from places like Element14/Farnell are near impossible. Anyway my mate went and bought 6 off eBay. Because you've built quite a few HID2AMI's and therefore have seen quite a few of these chips in your lifetime, I was hoping if you would be able to identify if these chips are real or fake. I've personally never had a good experience buying chips from eBay sellers. I've included some pictures: |

- from your pics I don't spot any *obvious* clue they are fake (e.g. wrong label font, fake part number, extra dimples, etc) - even if they were fakes, they could be useful anyway: hid2ami does not make use of analog, i2c, etc .. - you will gather more clues when, after having assembled a couple hid2ami, you'll generate unique board IDs. In general, fake clones tend not to have unique valid IDs inside (and then I can spot them easily) So my advice at this point is to assemble a couple boards and check what happens before assembling the remaining ones. |
