TSI KE15 INDEPENDENT CH CONFIG

Hi !

I'm using tsi_v5 and MKE15 uC.

Is possible configure hardware parameters for each TSI channel independently ?:

userConfig->commonConfig.mainClock = kTSI_MainClockSlection_0;

userConfig->commonConfig.mode = kTSI_SensingModeSlection_Self;

userConfig->commonConfig.dvolt = kTSI_DvoltOption_2;

...

userConfig->chargeCurrent = kTSI_CurrentMultipleChargeValue_1;

or it configs for all TSI Channels the same parameters?

my understand is that Init TSI function initializes all TSI channels with same features, can someone confirm ?

// Initialize the TSI
TSI_InitSelfCapMode(TSI, &userConfig);

tks

Hello Macgayver,

Your assumption is correct, the TSI driver initialization function configures all TSI channels with the same parameters. There are no individual configuration registers to allow each channel to have independent parameters.

I you haven’t read it I would recommend Application Note 3863 (AN3863, link below) which covers recommendations when using touch sensing electrodes.

I hope that this information helps!

Gustavo
