mccdaq

Go library to communicate with Measurement Computing Corporation (MCC) USB DAQs. Based on Dr. Warren J. Jasper's MCC DAQ C-based drivers. Many thanks to Dr. Jasper for his work.

WARNING: This code is in active development and should not be considered a stable API. Currently, it is not idomatic GO code, but I hope to change that in the near future.

Contributing

mccdaq is developed using Scott Chacon's GitHub Flow. To contribute, fork mccdaq, create a feature branch, and then submit a pull request. GitHub Flow is summarized as:

• Anything in the master branch is deployable
• To work on something new, create a descriptively named branch off of master (e.g., new-oauth2-scopes)
• Commit to that branch locally and regularly push your work to the same named branch on the server
• When you need feedback or help, or you think the branch is ready for merging, open a pull request.
• After someone else has reviewed and signed off on the feature, you can merge it into master.
• Once it is merged and pushed to master, you can and should deploy immediately.

Testing

Prior to submitting a pull request, please run:

$ gofmt
$ golint
$ go vet
$ go test
