PWM and PSOC 1 on Cypress

Simply drop a PWM8 or PWM16 user module into an unused digital block and connect the clock and output. The "code" (API) is described in the datasheet. You need to start it using PWM8_Start() and set the pulse width with PWM8_WritePulseWidth(BYTE bPulseWidth).

Sample code is given in the datasheet

Code:

/* include the Counter8 API header file  */

#include  "PWM8.h"



/* function prototype */

void GenerateOneThirdDutyCycle(void);



/* Divide by eight function */

void GenerateOneThirdDutyCycle(void)

{

    /* set period to eight clocks */

    PWM8_WritePeriod(23);



    /* set pulse width to generate a 33% duty cycle */

    PWM8_WritePulseWidth(7);



    /* ensure interrupt is disabled */

    PWM8_DisableInt();



    /* start the PWM8! */

    PWM8_Start();

}
