    Hi, is there a PWM function on the picaso processor

  • #2
    Hello,

    Unfortunately, Picaso processor doesn't have PWM out capabilities. Diablo16 processor based display modules has this feature readily available.

    As a workaround, you could implement a software PWM if you only need low resolution pulses. Attached below is project sample that
    demonstrate this. If you find this solution not applicable, you could also opt to use I2C PWM chips.

    I hope this will help.

    Good luck and best regards,
    Sherwin

      Hi,

      The maximum frequency is 100 Hz. You could change it by changing the value of duty cycle.

      Good luck and kind regards,
      Sherwin
