Posted on August 30, 2016 at 11:56Hi,
I'm trying to figure out, how to use the CubeMX generated project for touch sense aplication. I'm able to detect the change on the 3 touch buttons, but i can't figure out, how to detect on which touch button did the change arrived.
The code:
static void MX_TSC_Init(void)
{
/**Configure the TSC peripheral
*/
htsc.Instance = TSC;
htsc.Init.CTPulseHighLength = TSC_CTPH_2CYCLES;
htsc.Init.CTPulseLowLength = TSC_CTPL_2CYCLES;
htsc.Init.SpreadSpectrum = DISABLE;
htsc.Init.SpreadSpectrumDeviation = 0;
htsc.Init.SpreadSpectrumPrescaler = TSC_SS_PRESC_DIV1;
htsc.Init.PulseGeneratorPrescaler = TSC_PG_PRESC_DIV64;
htsc.Init.MaxCountValue = TSC_MCV_255;
htsc.Init.IODefaultMode = TSC_IODEF_OUT_PP_LOW;
htsc.Init.SynchroPinPolarity = TSC_SYNC_POLARITY_FALLING;
htsc.Init.AcquisitionMode = TSC_ACQ_MODE_NORMAL;
htsc.Init.ChannelIOs = TSC_GROUP2_IO1|TSC_GROUP2_IO2|TSC_GROUP2_IO3;
htsc.Init.SamplingIOs = TSC_GROUP2_IO4;
if (HAL_TSC_Init(&htsc) != HAL_OK)
{
Error_Handler();
}
}
//main
HAL_TSC_IODischarge(&htsc, ENABLE);
if (HAL_TSC_Start(&htsc) != HAL_OK)
{
Error_Handler();
}
while (1)
{
if (HAL_TSC_Start(&htsc) != HAL_OK)
{
Error_Handler();
}
while (HAL_TSC_GetState(&htsc) == HAL_TSC_STATE_BUSY)
{}
__HAL_TSC_CLEAR_FLAG(&htsc, (TSC_FLAG_EOA | TSC_FLAG_MCE));
if (HAL_TSC_GroupGetStatus(&htsc, TSC_GROUP2_IDX) == TSC_GROUP_COMPLETED)
{
// Store the acquisition value
uhTSCAcquisitionValue = HAL_TSC_GroupGetValue(&htsc, TSC_GROUP2_IDX);
}
HAL_TSC_IODischarge(&htsc, ENABLE);
}
Thanks for any help.
