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". Here, I will describe the addition of the design for sounding the piezoelectric buzzer.
The environment used is as follows:
・PSoC Creator 4.3
・CY8CKIT-044
PWM (PWM_2) and piezoelectric buzzer (external) were added to the previous circuit. The circuit of PSoC4 is as follows.
The pin assignments are as follows.
The added PWM_2 inputs a 1MHz clock, and the settings are as follows.
The program adds a start API for PWM_2.
#include "project.h"
uint32_t sw=0; //sw is off (Stop rolling dicce)
int main(void)
{
CyGlobalIntEnable; /* Enable global interrupts. */
/* Place your initialization/startup code here (e.g. MyInst_Start()) */
PWM_2_Start();
for(;;)
{
if(sw==0){
// if(Cy_GPIO_Read(SW2_PORT,SW2_NUM)==0){
if(SW2_Read()==0){
PWM_1_WritePeriod(400);
PWM_1_WriteCounter(0);
PWM_1_Start(); // Start rolling dice
sw=1;
}
}
if(sw==1){
//if(Cy_GPIO_Read(SW2_PORT,SW2_NUM)==1){
if(SW2_Read()==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
}
}
}
}
Thanks,
Kenshow

Hi Kenshow-san,
Thank you for sharing your example project with the community.
Best regards,
