Analog System
R2026bCreate Simulink® models with the analog peripherals such as ADC, CMPSS, Comparator, DAC, and more available on TI’s C2000™ microcontrollers. Configure the Simulink model to interface with supported target hardware using model configuration parameters. You can map tasks and peripherals in a model to hardware board configurations using Hardware Mapping tool. The blocks are processor specific and is not be available on all TI’s C2000 microcontrollers.

Featured Examples
ADC-PWM Synchronization Using ADC Interrupt
Use the ADC block to sample an analog voltage and use the PWM block to generate a pulse waveform. This example also shows how to use the Hardware Interrupt block to synchronize the change in the PWM duty cycle with analog to digital conversion of voltage. In the generated code, changes in the voltage of the ADC input alter the duty cycle of the PWM output. The period of the PWM waveform remains constant.
Using Comparator Subsystem (CMPSS) for Voltage Compare
Use the Comparator Subsystem (CMPSS) to compare the analog voltage signals for Texas Instruments™ C2000™ processors and monitor the status output. Using this example, you can:
Asynchronous Scheduling
Use the Texas Instruments™ C28x™ peripherals and Hardware Interrupt blocks to control the real-time execution of Simulink® function-call subsystems in an asynchronous fashion.
