|

//
|

//! \addtogroup driver_example_list
|

//! <h1>HRPWM Duty Control with SFO</h1>
|
||||
//!
|
||||
//! This example modifies the MEP control registers to show edge displacement
|
||||
//! for high-resolution period with ePWM in Up count mode
|
||||
//! due to the HRPWM control extension of the respective ePWM module.
|
||||
//!
|
||||
//! This example calls the following TI's MEP Scale Factor Optimizer (SFO)
|
||||
//! software library V8 functions:
|
||||
//!
|
||||
//! \b int \b SFO(); \n
|
||||
//! - updates MEP_ScaleFactor dynamically when HRPWM is in use
|
||||
//! - updates HRMSTEP register (exists only in EPwm1Regs register space)
|
||||
//! with MEP_ScaleFactor value
|
||||
//! - returns 2 if error: MEP_ScaleFactor is greater than maximum value of 255
|
||||
//! (Auto-conversion may not function properly under this condition)
|
||||
//! - returns 1 when complete for the specified channel
|
||||
//! - returns 0 if not complete for the specified channel
|
||||
//!
|
||||
//! This example is intended to explain the HRPWM capabilities. The code can be
|
||||
//! optimized for code efficiency. Refer to TI's Digital power application
|
||||
//! examples and TI Digital Power Supply software libraries for details.
|
||||
//!
|
||||
//! \b External \b Connections \n
|
||||
//! - Monitor ePWM1/2/3/4 A/B pins on an oscilloscope.

//! - returns 2 if error: MEP_ScaleFactor is greater than maximum value of 255
|

//! (Auto-conversion may not function properly under this condition)

//! - returns 1 when complete for the specified channel

// TITLE: HRPWM Duty Control with Up-Down, Active High Complementary Deadband.
|
||||
//
|
||||
//! \addtogroup driver_example_list
|
||||
//! <h1>HRPWM Duty Control with AHC Deadband</h1>
|
||||
//!
|
||||
//! This example implements High-Resolution EPWM duty control capability. The
|
||||
//! example begins with a basic Active-High Complementary (AHC) output
|
||||
//! on channels A and B of the EPWM module(s) by using the Dead Band submodule
|
||||
//! to apply rising and falling edge delays on channel A and B respectively.
|
||||
//! High-Resolution duty control is then applied on both A/B channels of the
|
||||
//! EPWM module(s). HR duty control is implemented by applying the CMPAHR
|
||||
//! (for channel A) and CMPBHR (for channel B) values to control both edges of
|
||||
//! both EPWM channel outputs with finer granularity. The duty cycle of the
|
||||
//! EPWM module(s) are updated with calculations performed in main().
|
||||
//! This example also calls the following TI's MEP Scale Factor Optimizer (SFO)
|
||||
//! software library V8 functions:
|
||||
//!
|
||||
//! \b int \b SFO(); \n
|
||||
//! - Updates MEP_ScaleFactor dynamically when HRPWM is in use
|
||||
//! - Updates HRMSTEP register (exists only in EPwm1Regs register space)
|
||||
//! with MEP_ScaleFactor value
|
||||
//! - Returns 2 if error: MEP_ScaleFactor is greater than maximum value of 255
|
||||
//! (Auto-conversion may not function properly under this condition)
|
||||
//! - Returns 1 when complete for the specified channel
|
||||
//! - Returns 0 if not complete for the specified channel
|
||||
//!
|
||||
//! This example is intended to explain the HRPWM capabilities. The code can be
|
||||
//! optimized for code efficiency. Refer to TI's Digital power application
|
||||
//! examples and TI Digital Power Supply software libraries for details.
|
||||
//!
|
||||
//! \b External \b Connections \n
|
||||
//! - Monitor ePWM1/2/3/4 A/B pins on an oscilloscope.
