Hello,

in my application I have a SW running on TC387 and I would like to understand how to port the code to TC322LP microcontroller.

I have looked at example code but there is only reference to TC334. I have also seen that the datasheet of TC322 is in common with TC33x so I suppose that a SW for TC334 is compatible with TC322, right?

Are there any difference in LLD?

Thanks,

Andrea

The TC3xx is a family concept meaning you have a lot of software compatibility  between devices. If the peripheral exists on the TC322 and the TC387 your software will work (albeit you may to choose different port pins). Their is a difference in the Power Management System as the TC322 uses the Low End version. Obviously you only have one core and you have to review the memory map differences.

Hello, 

thank you for your response. What about clock frequency? If I am not wrong, TC322LP runs at 160MHz while TC334 could un till 300 MHz.

In the code example of TC334 if I change CPU frequency define in Ifx_cfg.h building is failing.

Could you please tell me how to fit the code?

Thanks 

Andrea

You are correct when choosing the 160MHz option for the IFX_CFG_SCU_PLL_FREQUENCY it fails (missing defines). I added some defines that perhaps can work for you. Please note this not an official release by any means and you need to validate it for your use. I put the ifxScu_cfg.h file inside this zip file as you cannot upload a header file on its own 😕
