Hi,
I hope everything is going well. I have a question regarding using MATLAB to write code for the C2000 controller - F28035. I am currently implementing the TI Microinverter (TIDM-SOLARUINV) controlled by the F28035 using MATLAB. I have tested the input side MPPT and the output side inverter and grid integration.
However, I am uncertain about how to integrate both the PV and inverter together for grid integration. TI has used a state machine for grid connection as described on page 45 of the documentation (https://www.ti.com/lit/ug/tidu405b/tidu405b.pdf?ts=1716863482444&ref_url=https%253A%252F%252Fwww.ti.com%252Ftool%252FTIDM-SOLARUINV). Could you please provide some guidance or an example file on how to implement this in MATLAB? Your assistance would be greatly appreciated.
Thank you.

Hi take a look at this page, there are examples and videos on this topic, including example on deployment on F28035 from Simulink using C2000 support:

Hi
It seems we don't have any shipping example with state machine for your use case. My suggestion would be to take the Stateflow Onramp to learn about state machine modeling and then implement the logic yourself in Stateflow. It supports very well code generation for TI targets.
