TMS570LC4357: NHET black box driver assembler code

Hi Juergen,

Actually, there are two ways to generate the N2HET code,

1. The first way is using HALCoGen, this tool has a blackbox driver for the NHET which lets you create at most 8 PWMs (with variable frequencies).

2. The other way is using HET IDE, If you have a requirement of more than 8 PWM's or want to use complex timer functions like angle measurements etc then we should use this IDE for code generation.

You can refer below user guide to understand about HET IDE.

Hi Jagadish,

thanks for your answer, it's not the answer to my question, which was:
A couple of months ago, I found the code for the black box driver on TI's website. There was also a PDF document which depicted the program flow nicely. I can't find it anymore. My question was whether someone knows the link to it.

Best Regards,

Juergen

Hi Juergen,

I am not aware of any black box driver code.

I am forwarding your issue to my senior colleague, let's wait for his update on this.

Hi Juergen,

Do you mean the NHET PWM example or NHET IDE?
