From the project

Research into quantisation effects in MEMS gyroscopes using custom STM32 hardware.

Custom STM32F723 hardware, firmware and analysis for measuring output-register quantisation noise in MEMS rate gyroscopes. Specifically gyroscopes that report an angular-rate register rather than an integrated angle increment.

This is a pre-publication research project. The preprint is not yet released. the results, figures and numbers in this repository are working values and are subject to change. Nothing here has been peer-reviewed. Preliminary Datasets are available on Zenodo
