Introduction

The Shimmer Matlab Instrument Driver package is a set of Matlab .m files designed to assist users of the Shimmer2, Shimmer2r, Shimmer3 and Verisense in the development of Shimmer based applications in Matlab. Please proceed to for Verisense.

For Shimmer 3 devices to begin using the Shimmer Matlab Instrument Driver please refer to the Shimmer Matlab Instrument Driver User Manual. In order to communicate changes more effectively we will be transitioning to the use of Github and will no longer be updating the user guide from Rev2.9 onwards. We will maintain providing keeping the user guide in the repository for Shimmer3 users.
