Type Name
result< pwm > get (std::uint8_t p_peripheral, std::uint8_t p_channel)
Get a pwm driver.

Detailed Description

This driver uses the dedicated PWM peripherals, PWM0, and PWM1 for generating pwm signals. Other methods would include using timers and the MotorPWM peripherals.

NOTE: Channels within a PWM peripheral device are NOT independent. Meaning that changing the frequency of one channel changes the frequency for all channels within the peripheral block.

function get

Get a pwm driver. 

static result< pwm > hal::lpc40::pwm::get (
    std::uint8_t p_peripheral,
    std::uint8_t p_channel
)

Parameters:

  • p_peripheral - Peripheral block, either 0 or 1
  • p_channel - PWM output channel within the peripheral block, from 1 to 6.

Returns:

result<pwm&> - reference to the pwm driver
