DWIN HMI Screen Engineering
Authorised DWIN Technology Partner
Architected for Precision & Reliability
Authorised Beijing DWIN Technology engineering partner in India. Turnkey DGUS II UI development, interactive graphical widgets, animated gauges, and UART microcontroller drivers.
- Zero display code overhead on host MCU — GUI runs directly on DWIN T5L ASIC
- Simple 4-pin UART serial interface (TX, RX, VCC, GND) with binary frame protocol
- Support for round smart-knobs (2.1″), compact panels (2.8″/3.5″), and operator displays up to 21.5″
- Complete graphic design in DGUS II: real-time curves, alarm pages, and touch controls
