STM8L151F3 touch library 1.1.0

¿Has anybody succeeded in using STM8 touch library with STM8L151F3?, I'm having problems getting it working with HW adquisition, I have ported STM8L151C3_Ex01 to my board and the touch pins are at 0v all the time.

My board has just 2 touch buttons on PB4 and PB5, sampling capacitor is connected to PB6, all of them belong to group 5.

This is how library is configured:

#define TSLPRM_TOTAL_CHANNELS (2)

#define TSLPRM_TOTAL_BANKS (2)

#define TSLPRM_TOTAL_TOUCHKEYS (0)

#define TSLPRM_TOTAL_TOUCHKEYS_B (2)

#define TSLPRM_TOTAL_LINROTS (0)

#define TSLPRM_TOTAL_LINROTS_B (0)

#define TSLPRM_TOTAL_OBJECTS (2)

#define TSLPRM_TICK_FREQ (1000)

#define TSLPRM_USE_SHIELD (0)

#define CHANNEL_0_SRC ((uint8_t)(GR5))

#define CHANNEL_0_DEST (0)

#define CHANNEL_0_SAMPLE (PB6)

#define CHANNEL_0_CHANNEL (PB4)

#define CHANNEL_1_SRC ((uint8_t)(GR5))

#define CHANNEL_1_DEST (1)

#define CHANNEL_1_SAMPLE (PB6)

#define CHANNEL_1_CHANNEL (PB5)

#define BANK_0_NBCHANNELS (1)

#define BANK_0_SHIELD_SAMPLE (0)

#define BANK_0_SHIELD_CHANNEL (0)

#define BANK_1_NBCHANNELS (1)

#define BANK_1_SHIELD_SAMPLE (0)

#define BANK_1_SHIELD_CHANNEL (0)

CONST TSL_ChannelSrc_T MyChannels_Src[TSLPRM_TOTAL_CHANNELS] ={

   { CHANNEL_0_SRC, CHANNEL_0_SAMPLE, CHANNEL_0_CHANNEL },

   { CHANNEL_1_SRC, CHANNEL_1_SAMPLE, CHANNEL_1_CHANNEL },

};

CONST TSL_ChannelDest_T MyChannels_Dest[TSLPRM_TOTAL_CHANNELS] ={

   { CHANNEL_0_DEST },

   { CHANNEL_1_DEST },

};

CONST TSL_Bank_T MyBanks[TSLPRM_TOTAL_BANKS] ={

   {&MyChannels_Src[0], &MyChannels_Dest[0], MyChannels_Data, BANK_0_NBCHANNELS, BANK_0_SHIELD_SAMPLE, BANK_0_SHIELD_CHANNEL},

   {&MyChannels_Src[1], &MyChannels_Dest[1], MyChannels_Data, BANK_1_NBCHANNELS, BANK_1_SHIELD_SAMPLE, BANK_1_SHIELD_CHANNEL},

};

TSL_tIndex_T MyBankSorting[TSLPRM_TOTAL_BANKS] = {0, 1};

CONST TSL_TouchKeyB_T MyTKeysB[TSLPRM_TOTAL_TOUCHKEYS_B] ={

   { &MyTKeysData[0], &MyTKeysParams[0], &MyChannels_Data[CHANNEL_0_DEST] },//banco 0 0

   { &MyTKeysData[1], &MyTKeysParams[1], &MyChannels_Data[CHANNEL_1_DEST] },//banco 1 0

};

CONST TSL_Object_T MyObjects[TSLPRM_TOTAL_OBJECTS] ={

   { TSL_OBJ_TOUCHKEYB, (TSL_TouchKeyB_T *)&MyTKeysB[0] },

   { TSL_OBJ_TOUCHKEYB, (TSL_TouchKeyB_T *)&MyTKeysB[1] },

};

Is there anything wrong?

Thank you in advance
