ENDOR implementation using STM32 microcontroller
https://doi.org/10.26907/mrsej-23101
Abstract
The development of a simple device for the generation and control of radio frequency pulses, intended for experiments on pulsed electron nuclear double resonance (ENDOR), is presented. The device is implemented on a 32-bit microcontroller based on the Arm Cortex-M processor (STM32 family). The functionality of the device has been tested on an Elexsys E580 FT EPR spectrometer (Bruker, Germany) operating in the X and Q frequency bands. Within the limits of the developed device functionality it appeared to be compact and inexpensive, and comparable in performance to commercial devices
