CAN controlled and configurable milking controller for cattle milk dispensing. By employing complex actuator sequence realized through the two PWM channels and three ADC channels on pressure sensors, a smart milking system is realized. Status messages are shown on a small 320×240 TFT display.
Requirements:
- CAN network over opto-islated controller
- TFT LCD display for system status
- Firmware upgrade via CAN interface
- Differential pressure monitoring
- System parameter storage on non-volatile memory
Major components:
- STM32F103
- ADM3053
- ZXMS6005DG
- W25Q32
- MPX5500 & MPXV5100
Number of PCB layers: 2
BOM price: 99 USD
Realization time: 8 weeks
