Synchronized PWM ADC Queue Group Definition

This MotoHawk™ block creates a group of ADCQueues that are triggered to be sampled by a Synchronized PWM System.

Block ID

Synchronized PWM ADC Queue Group Definition

Library

motohawk_MotorControl_lib

Description

This MotoHawk™ block defines a Triggering Scheme where a group of ADC Queues will be sampled at configurable locations during the PWM Period of the referenced Synchronized PWM System Definition.

• The referenced Synchronized PWM System Definition provides the synchronisation with the PWM output.
• The referenced ADC Queue Definitions define ADC Queue Element lists that are to be sampled at predefined trigger locations
• The ADC Queue trigger locations are set using the Synchronized ADC Queue Group Set block.

Example

A 3 Phase PWM output with synchronised ADC samples. Five ADCQueues are sampled at various locations on a pair of ADC convertors.

In this system there are two ADC Queue Groups defined, one for each ADC. Then each group references a number of ADC Queues, and each queue references a number of ADC Queue Elements. In this example Synchronized ADC Queue Group Set for 'MyADC0QueueGroup' has been configured for [0%, 25%, 50%].

Block Parameters

Parameter Field	Values	Comments/Description
Name	Single quote enclosed alpha-numeric text	A unique, C-legal name that identifies the channel. A Synchronized ADC Queue Group Set will reference this name in order apply the ADC Queue sampling trigger offsets.
Resource	Drop down	Selects the resource that this block is to define.
Synchronized PWM System Reference Name	Single quote enclosed alpha-numeric text	The name of the Synchronized PWM System Definition that ADC Group is synchronized to.
ADC Queue Reference Name(s)	Cell array of single quote enclosed alpha-numeric text elements	Cell array list of one or more ADC Queue Definition names.
