PCA9685PW Frequently Asked Questions (FAQs)

  • The maximum frequency of the PWM output is 1526 Hz, which is the maximum value that can be set using the PRESCALE register.
  • The PWM frequency can be calculated using the formula: fPWM = 25000000 / (4096 * PRESCALE), where PRESCALE is the value set in the PRESCALE register.
  • The resolution of the PWM output is 12 bits, which means there are 4096 possible duty cycle values.
  • Yes, the PCA9685PW can be used as a simple I/O expander by setting the output mode to 'Output' and controlling the output state using the LEDn_ON and LEDn_OFF registers.
  • The PCA9685PW can be reset by setting the SLEEP bit in the MODE1 register to '1', then setting it back to '0'. This will reset the device to its default state.
