K70 pin mux utility tool

Hi,

I want to check pin-mux of K70 series microcontroller (like MK70FX512VMJ12), So is there tool available for checking pin-mux for this?

With Regards,

JAY PATEL

Hi Jay

The uTasker project includes port pin mux simulation and monitoring. It monitors the code operation so shows the present pin mode/state as shown below (eg. for K70 as on TWR-K70F120M board). The device and its package are configurable and so it works for all package types.

Hovering the mouse over the port of interest displays its location on the package, its possible peripheral functions, its present function and its logical state.

Hi Mark,

Thanks for your quick revert.

You have suggested for the Tower System (TWR-K70) while i am using only K70 SOM of FreeScale. So for that i want to interface different modules on I2C, SPI, SDHC, .. and so on.

So for that first i want to check how many interfaces are possible without any conflicts with muxed Pins.

I have used Pin-Mux Tool for i.MX6 series (named iomux_tool_v3.4.0). So is there any similar Tool available for Kinetis K70 Series Controllers?

Regards,

As I wrote - the TWR-K70 is an example - it is configurable for any package.

However to define which pins to use I would simply make a copy of the "K70 Signal Multiplexing and Pin Assignments" for the user's manual and draw circles around the ones that are to be used (sometimes simple old-fashioned techniques are just as easy).

The uTasker simulator verifies that the code is actually setting everything up as expected by verifying the register contents and is not intended specifically for chosing the functions of each.
