Exploring a capacitive sensing solution for a "3-element finger controlled wheel" using the MSP part.
https://software-dl.ti.com/msp430/msp430_public_sw/mcu/msp430/CapTIvate_Design_Center/latest/exports/docs/users_guide/html/CapTIvate_Technology_Guide_html/markdown/ch_design_guide.html#sliders-and-wheels
1) How robust and glitch-protected is this solution? Application is a finger-adjusted level control for an audio system. Could one glitch (body static discharge, etc.) cause the "encoding" to fail (e.g., go full scale or non-linear)? Is it suitably impervious to other kinds of glitching, such false increments (too many at once, or too few)?
1a) Are there macro's available for adjusting the speed and sensitivity, and perhaps acceleration parameters, for finger-controlled capacitive adjustment (wheel, slider, etc)?
2) What is the lowest-cost MSP430 solution that would give us 6 switch points and a 3-element wheel?
3) For hands-on testing of a "wheel" - which would be a better dev kit? The Captivate-TBSP or Captivate-PHONE? What other CAPTIVATE tools will be required for testing the wheel dynamics?
Tks.
