I'm developing with kinetis KL family microcontrollers (KL36 and KL46) using TSI for drive a capacitive keyboard built with ITO technology.
The TSI is influenced under the EN 61000-4-6 immunity test and this cause false touch and release events and wrong behaviour.
I'm using TSI with TSS support (TSS version is 3.1.0) and as I said the target have a capacitive keyboard built with ITO technology.
I'm trying some configurations and under EN 61000-4-6 test the best results are setting "AFID key detector"; setting "AFID key detector" the problems with noise injected are partially resolved, but when I remove the noise the TSI don't detect any other touches.
Has anyone had the same problem and can help me?
