Add Hardware Interrupt Trigger Block for Current Control Loop
In the Simulink® Library Browser, select and add the C28x Hardware Interrupt block from C2000™ Microcontroller Blockset > Scheduling.
In the block parameters dialog box, update the settings to configure the hardware interrupt ADCINT1. Also, identify and update the CPU and PIE interrupts for the hardware interrupt ADCINT1.
|Parameter in C28x Hardware Interrupt Block

In the current control subsystem, add a Trigger block and set the
Trigger type block parameter to
function-call. Connect this subsystem trigger input to
the C28x Hardware Interrupt block as shown in this figure.
In the Rate Transition block input to Current Control subsystem, change the
Output port sample time to
Add a Function-Call Generator block in variant source to support the
model simulation. In the Function-Call Generator block, set the
Sample time parameter as
Simulate the model with the updated driver blocks and check the simulation results in the Simulation Data Inspector. Variants ensure that ADC, PWM drivers, and interrupts are not active during simulation.
