README
README.mdLIN_MFSW_Adapter
Проект адаптера для установки новых MQB мультирулей на автомобили платформы PQ.
Аппаратно адаптер выполнен на микроконтроллере STM32F103C8T6, схема и печатная плата разработаны в среде KiCad. Печатная плата односторонняя, габаритные размеры 43 x 26 мм. В микроконтроллере задействованы 2 UART-порта, сконфигурированные в режиме LIN. UART1 работает в режиме Master и отправляет запросы на блок кнопок, UART2 в режиме Slave обрабатывает запросы от подрулевого блока. Прошивка написана в среде Keil 5 с использованием STM32Cube MX. Все действия выполняются в callback-функциях по окончании приёма/передачи по UART.
Устройство испытано на VW Passat B6 с подрулевым блоком 5K0953569T (SW 0180) и мультирулём 5E3419093CVKH. Его кнопки максимально имитируют работу кнопок старого 12-кнопочного
руля. Кнопки вызова ассистентов, управления обогревом руля и включения круиза пока не задействованы.
Сам адаптер установлен прямо в мультируль, под него вырезано место (на версиях мультируля с датчиками KLR здесь установлен контроллер KLR).

Questions
How big is the LIN MFSW Adapter PCB?
It measures 43 × 26 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LIN MFSW Adapter use?
29 parts, built around the TJA1021T/10/C, AMS1117-3.3 and LL4148. 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 LIN MFSW Adapter KiCad files?
From the mka1ugin/LIN_MFSW_Adapter repository on GitHub, at the commit this page was made from: the board is HW/LIN_MFSW_Adapter/LIN_MFSW_Adapter.kicad_pcb and its schematic HW/LIN_MFSW_Adapter/LIN_MFSW_Adapter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LIN MFSW Adapter design in my own project?
Its repository states no licence, so its author keeps all rights: ask mka1ugin before reusing the design.
