Amazing work Sampedenawa. Thanks a lot.

[Sampedenawa]

Thank you all for your appreciation !

If someone is going to build my board, at the end you will have to get the "App" from me (read the github, I hope the firmware flashing process description is clearly understandable, I tried to describe it as simple as possible ).

When it happens, contact me through the email address I put on github (anyway: EmberHeavyIndustries@gmail.com) and we will arrange the distribution of personalized "App" firmware.



As described in the github, I decided to release the hardware project as open, so anyone can build (or customize) his own board, but at the moment I will retain the firmware "App" closed, because in the past I have had a very negative experience, by releasing another project fully open source, and then finding after a couple weeks some "smart guys" selling dozen of cloned boards on ebay and making money with my project, without doing anything.

Tak Číňani oslavili nový rok a konečně vyrobili a odeslali PCB.

A kdy máme začít posílat kačky? Nebo to dopořešíme na Resetkání?

[Sampedenawa]

Hello,

I noticed you built pcbs. Well done ! If you have any question while assembling them, please ask !

Should someone be interested in pre-built boards, I have ordered a batch of 30 boards from a professional assembler (20 of them already reserved to users).

I've put a post on www.amibay.com; should anyone be interested, lpace a request there.

Thank you very much

Poporosím uvedené zájemce, ať mi napíší SZ s adresou. Pošlu to obyčejnou obálkou, cena bude asi 69,- Kč (50+19). Dodovi PCB předám na Foreveru. Poisonovi to zkusím osadit.

Hello Sampedenawa, I have some questions regarding the BOM.
Microcontroller STM... you stated that the package is TQFP-64. However, I only found a supplier offering a LQFP-64 packages. Do you think it is going to be ok ? At least, dimensions and pin spacing are identical for both versions, but the leads may be a little longer on LQFP. Thoughts ?

Same is regarding crystal - only HC-49/US package was available in stock, HC-49/S was not in stock. The footprint is identical.
Also, I could not find a suitable USB connector part, perhaps you could add a suggested part numbers into the BOM.

Thanks anyway.

Koupil jsem STM32F105RBT6 v pouzdře LQFP64 a sedne tam, to samé krystal v pouzdře HC-49/US. USB konektor sedl z GME. Pozor na D-SUB konektor, musí se koupit ten delší (není v GME, objednával jsem z TME).

A thought about pull up resistors on 5V line to Mosfets. A 100k seems a bit much. I have seen usually 4,7k or 10k resistors in such cases. I would say usage of 10k would be better noise-wise. I´ll definitely experiment with that. Thoughts ?

[Sampedenawa]

Hello rok,

it was a mistake from my side, the correct package *IS* LQFP (anyway, a TQFP stm32f105 does not exist).
I am going to fix the BOM at once !

With regards to the quartz, not a problem at all; just check the pin spacing. Being it a THC, it is easy to adjust even if it the ones you buy does not have a "perfect" pitch.

USB conns: I am using these ones:

The aim was to limit current consumption as maximum as possible: remember that Amiga has a 1/2W current limiting resistor in series of the joy/mouse ports +5V pin, so you do not have to exceed 100-110 mA. with modern high DPI mice, even saving 4 mA by using 100k instead of 10k pullup could make the difference. In any case, you are safely free to assemble 10k or even less.


A final note: if you need further info, feel free to write me emails @ EmberHeavyIndustries@gmail.com, so I can reply you quickly.
Posting here is good also, but I am not reading your forum every day (you will excuse me, but I really don't catch a word of Czech )

Thank you for your answers, it helped.
I will contact you when I am ready to burn the firmware :P

zdravím vespolek, hlásím že mám osazeno a vypálen FW, ale řeším konektor 9 pin canon do Amigy, mám A600 a s trochou síly to tam narvat jde. Máte někdo odzkoušeno který konektor je vhodný? A nevím zda mohu zabrousit plošňák.
Řeším teť FW...

[Solaris104]

Tak jsem si postavil svůj kousek. Nemám moc dobré vybavení a zkušenost, tak jsem si čip ARM nechal zapájet kamarádem. Zbytek jsem si osadil sám. Kompikací je, že FW není free, ale musíte si ho koupit a je svázáno s číslem vaší desky (5 EUR za poslední, 10 EUR doživotní aktualizace). Ale jinak mi to fungovalo na první zapojení. Flashování FW je jednoduché, potřebujete jen USB kabel A-A. Zatím jsem to testoval jen s USB myší, ale zvládá to i gamepady. Postavím slíbený kousek ještě Poisonovi. Budete chtít ještě další várku10ks PCB? Je tam už verze 1.1, která má lépe provedené zapájení stínění USB konektoru. U verze 1.0 jsem to pro jistotu zakápl lepidlem chemoprénem proti vytrhnutí.

Svazano s cislem vasi desky???

[Solaris104]

To 4 místné číslo je asi generované z ARM čipu, které se objevuje jako Version v SW DfuSe.

OK, svazane s unikatnim cislem cipu uz mi dava smysl.

Ikdyz..4 mistne cislo... neni to nejak malo nebo je ten ARM cip tak uzkoprofilove zbozi?

Happy to see that you succesfully built the board
I would be grateful if you send me a feedback about it: if the mouse movement is smoother to you, etc.
Also I am interested to konow if you test it with some mice / joypads not yet listed on compatibility list, so I can update the list more and more.

If you are planning to build more, and order new pcbs, I suggesto you to wait a few days; maybe next week I will put gerbers for Rev1.1 on the github.


Thanks !

Yes, the 4-digit code comes from the unique internal serial number inside of each chip. Each copy of the firmware is generated and works only with its paired code.

[Sampedenawa]

Updated github with rev1.1.0 schematics, BOM, and Gerbers.

Firmware App is fully compatible with both Rev1.0.0 and Rev1.1.0
