I have a problem with touch sensing on STM8L151K4, It is impossibe to increase number of touch key to 12.

I use sample project in STM8L_Touch_Lib and re-config the channel in 'tsl_user.h'. It work if i configure 6 keys but doesn't work if i configure 7,8,9,..keys.

Could anyone help me?

and the provided

It has 10 key + 1 slider + 1 wheel (=16 channels).

It may help you figure out what is wrong in you program.

Hi Max,

I've checked.

If I configure to run with only 1 key, It work for all my touch key on my own board.

But when I try to group 6 keys into BANK0, and the others to BANK1, It do not work.

All key State is TSL_STATEMASK_OFF.

Here my code:
