LIN bus demo using Mercedes-Benz W213 AMG coolant pump (STM32G474RE)

My strong inclination towards electric drives made me knock together another sequel to the Toyota RAV4 climate control panel. We are going to communicate over the LIN bus with a coolant pump. The part number is A0005002686 (Bosch).

Don't worry 🙂 Just log in to MyST and hit Alt-K to generate /Drivers/CMCIS/ and /Drivers/STM32G4xx_HAL_Driver/ based on the .ioc file. After a couple of seconds your project will be ready for building.
