CodeWarrior v10.3 PE工具模拟触摸按键功能

qinghao2010

请问大牛们，如何实现一次只能触摸一个按键，如果手指放在某个触摸键上，那么其他按键将无法被检测到。

我知道答案 目前已有4人回答

你把问题描述的再清楚一点，你采用的芯片是哪个？硬件上大致如何连接？

采用的是MKL25Z128VLK4芯片，现在使用codewarrior v10.3 PE工具的TSS实现触摸按键,全部9个按键触摸功能已实现,问题是现在的按键是多点触摸的,可以同时触摸多个按键,现在需要解决的问题是单个按键触摸,如果同时多个按键被触摸只能识别最早被触摸的那个,请问如何实现,使用PE工具实现还是自己重新写代码解决？

还想请教个kl25  TPM问题
TPM模块代码如下(使用PE生成)：
LDD_TDeviceData* TU1_Init(LDD_TUserData *UserDataPtr)
{
    TU1_TDeviceData *DeviceDataPrv;
   DeviceDataPrv = &DeviceDataPrv__DEFAULT_RTOS_ALLOC;
  DeviceDataPrv->UserDataPtr = UserDataPtr; /* Store the RTOS device structure */
   DeviceDataPrv->SavedISRSettings_TUInterrupt.isrData = _int_get_isr_data(LDD_ivIndex_INT_TPM1);
  DeviceDataPrv->SavedISRSettings_TUInterrupt.isrFunction = _int_install_isr(LDD_ivIndex_INT_TPM1, TU1_Interrupt, DeviceDataPrv);
    //SIM_SOPT2 |= SIM_SOPT2_TPMSRC(1);
  SIM_SCGC6 |= SIM_SCGC6_TPM1_MASK;                                                   
  TPM1_SC = 0x00U;                     /* Clear status and control register */
   TPM1_CNT = 0x00U;                    /* Reset counter register */
   TPM1_C0SC = 0x00U;                   /* Clear channel status and control register */
   TPM1_C1SC = 0x00U;                   /* Clear channel status and control register */
  TPM1_MOD = TPM_MOD_MOD(0xFFFF);      /* Set up modulo register */
   TPM1_C1SC = TPM_CnSC_CHIE_MASK |
              TPM_CnSC_MSB_MASK |
              TPM_CnSC_ELSB_MASK |
              TPM_CnSC_ELSA_MASK;      /* Set up channel status and control register */
    TPM1_C1V = TPM_CnV_VAL(0x0);      /* Set up channel value register */
  PORTE_PCR21 = (uint32_t)((PORTE_PCR21 & (uint32_t)~(uint32_t)(
                 PORT_PCR_ISF_MASK |
                 PORT_PCR_MUX(0x04)
                )) | (uint32_t)(
                 PORT_PCR_MUX(0x03)
                ));                                                 
  DeviceDataPrv->EnEvents = 0x01u;     /* Enable selected events */
   NVIC_IPR4 = (uint32_t)((NVIC_IPR4 & (uint32_t)~(uint32_t)(
               NVIC_IP_PRI_18(0x7F)
              )) | (uint32_t)(
               NVIC_IP_PRI_18(0x80)
              ));                                                 
  /* NVIC_ISER: SETENA|=0x00040000 */
  NVIC_ISER |= NVIC_ISER_SETENA(0x00040000);                                                   
    TPM1_SC = TPM_SC_CMOD(0x01) | TPM_SC_TOIE_MASK | TPM_SC_PS(4);         /* Set up status and control register */
  TPM1_SC |= TPM_SC_TOF_MASK;
  TPM1_C1SC |= TPM_CnSC_CHF_MASK;
  /* Registration of the device structure */
  PE_LDD_RegisterDeviceStructure(PE_LDD_COMPONENT_TU1_ID,DeviceDataPrv);
  return ((LDD_TDeviceData *)DeviceDataPrv); /* Return pointer to the device data structure */
}
 
void TU1_Interrupt(LDD_RTOS_TISRParameter _isrParameter)
{
  TPM1_SC &= ~TPM_SC_TOF_MASK;
  TPM1_C1SC &= ~TPM_CnSC_CHF_MASK;
   TU1_TDeviceDataPtr DeviceDataPrv = (TU1_TDeviceDataPtr)_isrParameter;
  LDD_TEventMask State = 0U;
  if ((TPM_PDD_GetChannelInterruptFlag(TPM1_BASE_PTR, ChannelDevice[0])) != 0U) { 
    State |= LDD_TIMERUNIT_ON_CHANNEL_0; /* and set mask */
  }
  State &= DeviceDataPrv->EnEvents;    /* Handle only enabled interrupts */
  if (State & LDD_TIMERUNIT_ON_CHANNEL_0) { /* Is the channel 0 interrupt flag pending? */
    TPM_PDD_ClearChannelInterruptFlag(TPM1_BASE_PTR, ChannelDevice[0]); /* Clear flag */
    TU1_OnChannel0(DeviceDataPrv->UserDataPtr); /* Invoke OnChannel0 event */
  }
}
 
具体问题如下：
 TU1_interrupt(); 只是初始进入一次，其后都不能进入
但是TPM1_CNT一直都是在计数，溢出后能自动清零从新开始
