Other Parts Discussed in Thread: CAPTIVATE-PGMR
Dear Ladies and gentleman,
We are using a MSP430 fr2533, for a Touch button project,
Currently we are encountering a seemingly random behaviour where our device is not detecting a touch after start up.
Sometimes after Boot up (~ every 10. time) touches are not detected until the next power cycle.
In a diagnostic program we can trace the touch detection and a so called PDV1 value that mirrors the filter Count – LTA . In the error cases, the threshold is seemingly calibrated to a high, so that a normal touch is not reaching the it.
After a power- cycle the error is soften gone.
The physical environment in the test scenario stays the same for every power cycle
Are there known reasons that the threshold is calculated so high after the start-up.
Are there any parameters for the captivate-library that may stabilize the threshold?
Are there any known mistakes that might have been made in order to this behaviour to occur?
Thank You for your support
