Struct esp32_hal::mcpwm::operator::DeadTimeCfg

pub struct DeadTimeCfg { /* private fields */ }

Configuration for MCPWM Operator DeadTime It’s recommended to reference the technical manual for configuration

Implementations

impl DeadTimeCfg

pub fn new_bypass() -> DeadTimeCfg

Uses the following configuration:

• Clock: PWM_clk
• Bypass: A & B
• Inputs: A->A, B->B (InSel)
• Outputs: A->A, B->B (OutSwap)
• No Dual-edge B
• No Invert
• FED/RED update mode = immediate
• FED/RED = 0

pub fn new_ahc(red_delay: Option<u16>, fed_delay: Option<u16>) -> DeadTimeCfg

Active High Complementary (AHC) from Technical Reference manual

Will generate a PWM from input PWMA, such that output PWMA & PWMB are each others complement Except during a transition in which they will be both off (as deadtime) such that they should never overlap, useful for H-Bridge type scenarios

Default delay on both rising (red) and falling (fed) edge is 16 cycles

pub fn set_delay(&mut self, rising_edge: u16, falling_edge: u16)

Sets the delay for the FED/RED module

pub fn invert_output(&mut self, fed: bool, red: bool)

Sets FED/RED output inverter Inverts the output of the FED/RED module (excl DEB mode feedback)

pub fn set_output_swap(&mut self, stream: PWMStream, swap: bool)

Swaps the output of a PWM Stream i.e. If streams have output_swap enabled, the output of the module is swapped, while if only one is enabled that one ‘copies’ from the other stream

pub fn set_bypass(&mut self, stream: PWMStream, enable: bool)

Set PWMA/PWMB stream to bypass everything except output_swap This means no deadtime is applied when enabled

pub fn select_clock(&mut self, pwm_clock: bool)

Select Between PWMClk & PT_Clk

pub fn select_input(&mut self, fed: PWMStream, red: PWMStream)

Select which stream is used for the input of FED/RED
