Firmware was developed for a professional coffee machine available in 2- to 4-group configurations. Each group is equipped with an HMI interface featuring three programmable backlit keys, a graphic display with capacitive touch, and a digital lever for flow adjustment. The machine is structured around three main logic units: Control Board (STM32-based), HMI Board (PIC32-based), and DFR Board (PIC16-based).
Kalpa managed the design, development, integration, and testing of both the application firmware and bootloader for all components, ensuring coordinated and reliable system operation.
