difference between tms320f2812 and tms320f28335??

Hi Sandeep,

I was working on closed loop system for power electronic converters, using the software tool PSIM, which generates the code  for TMS320F28335. But my university has only TMS320F2812 ezdsp (from spectrum digital). can some some please say the difference between both of them and if the code for 28335 can be used with 2812.

You being new to TI C2000 series of controllers; first of all welcome to family! I would suggest you to go through this documentation to get the basic difference between F2812 (Piccolo Family) and F28335 (Delfino Family).

In short Delfino family is very much advanced and powerful if compared to Piccolo family.

my closed loop system contains only integration and differentiation ,with some math equations, I need to collect output form sensors and need to process them to get the required PWM sigal for 2 switches.

Implementing the above in F28335 would consume hardly anything as this has a floating point unit with 150MHz of clock speed etc. But achieving the same with F2812 would be a challenge as this has a fixed point unit, a very  less clock speed etc. Refer the datasheets for more info. Also, you'll get less support on F2812 controller on this forum as it has completed its 15yrs of life cycle!

You can very much implement above application using F2812 but you'll have take the help of IQMath library for optimizing your control loop calculations and other computations.

Hi Sandeep,

In addition to Gautam's advice, the below F281x to F28x3x migration guide may also be useful for you.  Note that you'll be working in reverse.

If you wish to look at the F28335 instead, I believe the best kit to start experimenting with the F28335 is the following kit:
