Hi all,

The electronic dice I posted last time was very popular. Many people have requested that we make on PSoC 4 version, so I made it based on CY8CKIT-044. See previous post for more details on the design of the "PSoC 4 Seven Eyes Dice" and “PSoC 4 Seven Eyes Dice with sound”. Here, I will describe using a proximity sensor instead of a switch.

The environment used is as follows:

PSoC Creator 4.3

CY8CKIT-044

CapSence for proximity sensor is added to the previous circuit. The circuit of PSoC4 is as follows.

The pin assignments are as follows.

The settings of the CapSense component used in CE of CY8CKIT_044_CapSense_Proximity are used as they are.

The settings are as follows.

The program adds CapSense Proximity instead of SW2.

int main(void)

{

        /* Proximity sensor state. */

       uint8 proximity  = INACTIVE;

    CyGlobalIntEnable; /* Enable global interrupts. */

        /* Enable and start the CapSense block. */

       CapSense_Start();

       /* Initialize the baselines of all CapSense widgets. */

       CapSense_InitializeSensorBaseline(CapSense_PROXIMITYSENSOR__PROX);

       /* Enable and start PWM block. */

    PWM_2_Start();

    for(;;)

    {

        /* Update the baseline of the proximity sensor. */

              CapSense_UpdateSensorBaseline(CapSense_PROXIMITYSENSOR__PROX);

              /* Scan the proximity sensor. */

              CapSense_ScanSensor(CapSense_PROXIMITYSENSOR__PROX);

        while(CapSense_IsBusy())

              {

                     /* Put the PSoC 4200M in Sleep power mode while the CapSense is scanning.

                      * The device wakes up using the interrupt generated by CapSense CSD Component

                      * after scanning. */

              }

              /* Check if proximity sensor is active. */

              proximity = CapSense_CheckIsSensorActive(CapSense_PROXIMITYSENSOR__PROX);

              if(proximity == ACTIVE)

              {

                     /* Set the LED at a brightness level corresponding

                      * to the proximity distance. */

            if(sw==0){

                PWM_1_WritePeriod(400);

                PWM_1_WriteCounter(0);

                PWM_1_Start();  // Start rolling dice

                sw=1;

            }

        }

              else /* Proximity sensor is inactive. */

              {

            if(sw==1){

                /* Roll dice slowly */

                PWM_1_WritePeriod(1000);

                PWM_1_WriteCounter(0);

                CyDelay(1500);  // keep rolling slowly for 1.5sec

                PWM_1_Stop();// Stop rolling dice                   

                sw=0;           // sw is off   

            }

              } 

    }

}

The dice rolls when you hold your hand over the proximity sensor, and the dice slowly rolls when you move it away, and then stops.

Thanks,

Kenshow

Hi NoriakiT_91​,

Awesome! Thanks for your contribution

Hi

I noticed that the decoding logic part of the circuit I posted last time can reduce the inverter part. I will post the modified version here.
