PSoC4100SP:CapSense resolution bit

[RyYo_1406951]

Below, the same sentences are written in English and Japanese.

・Engilsh
Currently, there is no sensor board.
However, I want to know the approximate scan time.

Is there a formula for calculating the resolution bit value to be set from Cp (parasitic capacitance)?

・日本語(Japanese)
現在、センサ基板が無い状況です。
しかし、スキャン時間の概算を知りたいです。

Cp(寄生容量)から、設定すべきresolution bitの値を求める計算式ありますか？

Regards

The actual duration to complete a scan is sum of duration of hardware scan, duration of initialization prior a scan and duration of firmware execution.

The duration of hardware scan is based on the formula (2^n-1)/ Mod_Clk.

However, it would be difficult to estimate duration of software parts (i.e. Initialization prior a scan and firmware execution). Because it depends on how software is implemented.
