ADC Read

Read ADC data values from ADC Interface block

Since R2020b

• 

Libraries:
SoC Blockset / Processor I/O

Description

The ADC Read block converts the message received from the ADC Interface block to a signal that can be used by an algorithm. The data type of the output signal is the same as the data type in the contained data massage.

Examples

Simulate Analog to Digital Conversion for MCU

A minimal ADC simulation for an MCU using SoC blocks.

Ports

Input

msg — Data message from register

scalar

This message port receives ADC value messages from a connected ADC Interface block. The messages process when the Task Manager block triggers a task containing the ADC Read block. For more information on messages, see Messages.

Data Types: SoCData

Output

data — Output signal

scalar

This port emits a measurement from the ADC Interface block.

Data Types: double | single | int8 | int16 | int32 | uint8 | uint16 | uint32

Parameters

Data type — Data type of ADC measurements received

double (default) | single | uint8 | int8 | int16 | int32 | uint16 | uint32

Select the data type of the input data. Match this data type with data type of the ADC hardware.

Sample time — Sample time

-1 (default) | nonnegative scalar

Specify how often the scheduler runs this block. If this value is -1 (default), the scheduler assigns the sample time for the block.

Extended Capabilities

C/C++ Code Generation

Generate C and C++ code using Simulink® Coder™.

When deployed to a supported hardware board, this generated code for this block reads the ADC registers in the MCU for the specified ADC module. For more information on configuring the register settings, see Hardware Mapping and Hardware Mapping Peripherals for Texas Instruments C2000 Processors Properties.

Note

Supported hardware boards include the TI Delfino F2837xD and TI Delfino F2837xD LaunchPad from the SoC Blockset™ Support Package for Texas Instruments^® C2000™ Processors.
