Hello, Dear TI Technical Engineer

I need to use F28034 for log10 operations now, but it seems that F28034 does not support this operation, do I have any other way to implement log10 operations?

Are you looking to perform log10 on a 16-bit integer? 32-bit integer?

This device doesn't have TMU or FPU.

Is there any alternative to log10？

You could find some alternatives if you look up online, such as look up table based approaches, but I don't have expertise in them.

Can I use #include <math.h> log10 in the library in C, and is there any risk associated with this?

Of course you can, it will just be inefficient (compared to hardware) in terms of cycles.
