Licensee will exercise at least the +same amount of diligence in preserving the secrecy of the Confidential +Information as it uses in preserving the secrecy of its own most valuable +confidential information, but in no event less than reasonable diligence. +Information shall not be considered Confidential Information if and to the +extent that it: (i) was in the public domain at the time it was disclosed or +has entered the public domain through no fault of Licensee; (ii) was known to +Licensee, without restriction, at the time of disclosure as proven by the +files of Licensee in existence at the time of disclosure; or (iii) becomes +known to Licensee, without restriction, from a source other than InvenSense +without breach of this Agreement by Licensee and otherwise not in violation +of InvenSense's rights. + +5.2. Return of Confidential Information. Notwithstanding the foregoing, all +documents and other tangible objects containing or representing InvenSense +Confidential Information and all copies thereof which are in the possession +of Licensee shall be and remain the property of InvenSense, and shall be +promptly returned to InvenSense upon written request by InvenSense or upon +termination of this Agreement. + +6.

Notwithstanding the foregoing, Licensee +may assign this Agreement to a successor to all or substantially all of its +business or assets to which this Agreement relates that is not a competitor +of InvenSense. + +7.3. Governing Law; Venue. This Agreement shall be governed by the laws of +California without regard to any conflict-of-laws rules, and the United +Nations Convention on Contracts for the International Sale of Goods is hereby +excluded. The sole jurisdiction and venue for actions related to the subject +matter hereof shall be the state and federal courts located in the County of +Orange, California, and both parties hereby consent to such jurisdiction and +venue. + +7.4. Severability. All terms and provisions of this Agreement shall, if +possible, be construed in a manner which makes them valid, but in the event +any term or provision of this Agreement is found by a court of competent +jurisdiction to be illegal or unenforceable, the validity or enforceability +of the remainder of this Agreement shall not be affected if the illegal or +unenforceable provision does not materially affect the intent of this +Agreement. If the illegal or unenforceable provision materially affects the +intent of the parties to this Agreement, this Agreement shall become +terminated. + +7.5. Equitable Relief. Licensee hereby acknowledges that its breach of this +Agreement would cause irreparable harm and significant injury to InvenSense +that may be difficult to ascertain and that a remedy at law would be +inadequate. Accordingly, Licensee agrees that InvenSense shall have the right +to seek and obtain immediate injunctive relief to enforce obligations under +the Agreement in addition to any other rights and remedies it may have. + +7.6. Waiver. The waiver of, or failure to enforce, any breach or default +hereunder shall not constitute the waiver of any other or subsequent breach +or default. + +7.7. Entire Agreement. This Agreement sets forth the entire Agreement +between the parties and supersedes any and all prior proposals, agreements +and representations between them, whether written or oral concerning the +Software. This Agreement may be changed only by mutual agreement of the +parties in writing. + diff --git a/60xx/libsensors_iio/MPLSensor.cpp b/60xx/libsensors_iio/MPLSensor.cpp new file mode 100644 index 0000000..031ae6e --- /dev/null +++ b/60xx/libsensors_iio/MPLSensor.cpp @@ -0,0 +1,2764 @@ +/* +* Copyright (C) 2012 Invensense, Inc. +* +* Licensed under the Apache License, Version 2.0 (the "License");
