Dekoder funkcji DCC

Dekoder funkcji DCC z przeznaczeniem do sterowania oświetleniem wagonów. Część sprzętowa w przygotowaniu.

Elementy projektu

funcdec_proto3208.X
Prototypowe oprogramowanie dla ATMega3208 (0-series). Odebrane pakiety DCC są dodatkowo dekodowane do HEX i wysyłane na port szeregowy.
funcdec_mk1.X
Oprogramowanie dla ATTiny 1614 (1-series).

Tryby pracy: tylko DCC.
Tryby programowania: tryb serwisowy na torze programującym.
Adresowanie: długie (domyślnie) i krótkie.
Wyjścia funkcyjne: zależnie od implementacji sprzętowej.

Wersje sprzętowe

Dekoder uniwersalny.
6 wyjść funkcyjnych z indywidualnym ściemnianiem.

Kompilacja oprogramowania

Projekt MPLABX (wersja 5.35) z kompilatorem gcc dołączonym do pakietu XC8 (wersja 2.10). Użyto pakietów definicji dostarczonych wraz z MPLABX.

Questions

How big is the Funcdec uni.hw PCB?

It measures 32 × 17.5 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Funcdec uni.hw use?

27 parts, built around the ATTINY1614-SSN and PMEG4010ER. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the Funcdec uni.hw KiCad files?

From the robusnagus/DCCdecoder repository on GitHub, at the commit this page was made from: the board is funcdec_modB.hw/funcdec_uni.hw.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Funcdec uni.hw design in my own project?

Its repository states no licence, so its author keeps all rights: ask robusnagus before reusing the design.
