Posted on June 07, 2017 at 16:56¿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
