Abstract:

A high speed and reliable communication system based on the CAN (Controller Area Network) bus, STM32 controller, FPGA (Field Programmable Gate Array) and PCI-104 was designed for nuclear magnetic resonance (NMR) spectrometer. Ethernet-CAN bus communication between the NMR workstation and each controller was established and programmed with reusable method. The results from typical tuning experiment revealed that the CAN-based communication system is an ideal scheme for data communication in NMR spectrometer.

Key words: NMR, CAN bus, multi-node communication, STM32, tuning
