=PWM Injector Output=

This MotoHawk™ block, PWM Injector Output, is similar to the PWM Output block, except it supports driving peak-and-hold injectors with a variable peak-time.

==Block ID==

motohawk_pwm_injector

==Library==

MotoHawk_lib/Analog I/O Blocks

==Description==

[[Image:PWM_Peak_and_Hold_Output.PNG]]

The Duty Cycle input is an int16, ranging from -4096 to 4096, where 0 is 0%, 4096 is 100%. When negative, the polarity is reversed, which is only valid on PWM resources that are H-Bridge outputs, like ETC or H1. The Frequency input is a uint32, ranging from 119 to 19988175. Each unit represents 0.01Hz. The Peak Time input is a uint16, ranging from 0 to 65535. Each unit represents 1 microsecond. When the Peak Time is set to 0, there is no peak-and-hold behavior, and the entire waveform will operate at peak current.
