Add Hardware Interrupt Trigger Block for Current Control Loop
In Simulink library browser, select C28x Hardware Interrupt block from Embedded Coder Support Package for Texas Instruments C2000 Processor > Scheduling.
In C28x Hardware Interrupt block mask dialog, update the settings to configure hardware interrupt ADCINT1. From the C28x Hardware Interrupt, identify the PIE and CPU for ADCINT1.
| Parameter in C28x Hardware Interrupt Block | Settings |
|---|---|
CPU interrupt numbers | [1] |
PIE interrupt numbers | [2] |
In Current control, add a Trigger block and change the Trigger type to
function-call. Connect this subsystem trigger input to the
Hardware interrupt block as shown in the below figure.
In the Rate Transition block's input to Current Control, change the sample time to -1.
Add a Function-Call Generator block in variant source to support the model simulation. In Function-Call Generator, set the Sample time as Ts (50e-6).
Simulate the model with updated drivers blocks and ensure that the simulation results in Simulink Data Inspector. Variants ensure that ADC, PWM drivers and interrupts are not active for simulation.
