MSP430G2433: A question on MSP430G2433 to implement Cap touch slider

Part Number: MSP430G2433
Other Parts Discussed in Thread: MSP430G2302

Dear MSP430 Champs,

Right now, we have a question on MSP430G2433 to implement Cap touch slider.

The question is on MSP430G2433, the cap touch sensitivity is too low and the cap touch scan data is not stable(sometime it is always near 0).

The major confused thing is we used the MSP430G2302 to implement cap touch with the same cap lib and almost same HW, it works. But we update the MCU to G2433, it failed. 

Slider scan mode: RO_PINOSC_TA0_WDTp

Slider scan cycle: WDTp_GATE_32768

The slider is made by 9 element

Cap touch SW lib: http://www.ti.com/tool/capsenselibrary

Thanks and best regards,

Hardy
