Hledám šikulu co umí navrhovat plošný spoj. Osazení tlačítek, otočných ovladačů, komunikace s pc přes usb. Ideálně Praha / SČ / JČ

Dobrý den, pro svůj projekt, ktery je řízen procesorem STM32L432KC potřebuji napsat jednoduchý bootloader. Nemohu využít bootloader, který je standardně na čipu jelikož komunikace probíhá přes piny PB6 a PB7, kde není UART bootloader dostupný. Bohužel ostatní piny jsou plně využité. Komunikace s PC je přes FTDI chip a USB jako standardní virtual Com port. Funkce bude standardní. Po restartu bootloader čeká na příkaz a pokud nepříjde (do cca 5s) jde rovnou na aplikaci. Pokud přijde čeká na poslání dat nového FW a po uspěšném zapsaní skočí na aplikaci. Je dán komunikační protokol, data jsou posíl&...

Cílem projektu je vytvoření aplikace pro iPad Air s následující funkcionalitou. App nebude určena pro distribuci v AppStoru, ale pro provoz pouze na jednom konkrétním stroji. Aplikace by měla sledovat obsah složku fotek a zobrazovat vždy poslední pořízenou na celou obrazovku. Fotky budou do iPadu přibývat prostřednictvím eye-fi karty. Ale varianta přenosu USB kabelem z foťáku je též možná. Druhou částí aplikace by mělo být, že po ťuknutí do displaye by mělo vyskočit "okno" s tiskem a poslat fotku do tiskárny po wifi.
