Revision History¶
This chapter tracks changes in the CapTIvate Technology Guide and CapTIvate Software Library. Technology Guide revision tracking was added for release 1.40.00.00.
Revision History of CapTIvate Technology Guide Releases¶
Release v1.83.00¶
Release Date: 2020-May-18
Design Guide
Added Trackpad sensor documentation
Software Library
Added support for Trackpad sensors.
Design Center
Added support for Trackpad sensors.
Release v1.82.00¶
Release Date: 2020-January-22
Design Guide
Documentation updates.
Device Family
Add the support for new devices MSP430FR2672 and MSP430FR2673.
Software Library
Minor bug fixes.
Design Center
Added the Recommended Threshold Percentage calculation and warning feature to help the user to set a reliable proximity and touch threshold.
Add project version check function.
Release v1.81.00.00¶
Release Date: 2019-August-15
Design Guide
Added section on “Button Performance as a Function of Overlay Thickness and Electrode Size”.
Added section on “The Effect of Batteries on Capacitive Touch Systems”.
Updated Sliders and Wheels chapter.
Device Family
Added CapTIvate key parameter performance under different test condition table.
Software Library
Added section “Implement custom slider/wheel position algorithm”.
Technology
Updated this chapter.
Added CAPTIVATE-EMC Chapter
Release v1.60.00.00¶
Release Date: 2017-December-05
Design Guide
Added section for transparent touch
Updated the mutual capacitance electrode design recommendations to specify a 0.5mm RX-TX spacing for buttons. This improves measurement accuracy with respect to the prior guidance of 1/2 the overlay thickness, which optimizes for best sensitivity.
Device Family
Added device selection section to provide guidance on choosing a device for an application
Updated devices section to include the new MSP430FR2522 and MSP430FR2512 devices
Added device migration description section
Software Library
Added section for calibration to discuss standard calibration and max offset calibration methods
Added section for host processor communication
Added BOOSTXL-CAPKEYPAD Development Kit Chapter
Release v1.50.00.00¶
Release Date: 2017-July-14
Design Guide
Best Practice - Mechanicals
Updated the Overlay section
Updated the Gap section
Added the coupling material section
Best Practice - Common Layout Considerations
Updated the Ground Planes section
Added section for Metal Touch
MSP-CAPT-FR2633 Development Kit
Sensor Panel Demonstrations
Added CAPTIVATE-METAL section describing the three metal touch demos
Hardware
Added CAPTIVATE-METAL section describing sensor design, mechanical stackup
Release v1.40.00.00¶
Release Date: 2017-March-23 - Design Guide - Proximity - Added Proximity Design Considerations section. - Modified Proximity Ground and Shielding section. - Added Proximity Range Test section. - Noise Immunity - Updated noise immunity design guide to include updated ESD, EFT, and conducted immunity information.
Software Library
Updating the Getting Started: Adding CapTIvate to an Existing Project guide to cover multiple device object libraries and ROM header files.
Updating the Advanced Module: EMC Module Configuration section to include a description of the eMultiFrequencyWithOutlierRemovalAndErrCorrection conversion mode.
Updating memory size benchmarks
Removed how-to description for using a CapTIvate™ IO pin as a driven shield. Will replace with more accurate information in future releases.
Device Family
Adding ROM header file and pre-compiled object library columns to the device family description tables to indicate which ROM header files and which pre-compiled libraries correspond to a given device.
Glossary
Updating the touch threshold description to clarify that the maximum valid touch threshold in self capacitance mode is 127, as 128 would result in the threshold point being calculated as LTA - (LTA/128)*128, or LTA-LTA, which results in a threshold point of zero. In mutual mode, thresholds greater than 127 may be used.
Revision History of CapTIvate Software Library Releases¶
Although CapTIvate™ Software Library and CapTIvate™ Design Center GUI are delivered together, the CapTIvate Software Library has its own version tracking and change control. Every major library release comes with change control data in the Software Library API guide that describes any new features that have been added and any changes to existing functionality. - Access the software library change control document - Access the software library API guide
