I really appreciate this utility - it saves A LOT of time trying to get the pins setup correctly. I would like to make a request, can you add a column for user comments after the mode 7 column? I would like this comment appended to the comment you are already adding in the header. Adding this column will help me keep track of board specific settings of the pins.

Thanks!!

Is the source code for the PinMux utility itself available somewhere?

I agree with Ranye. Since GPIO pins typically get a specific function, it would be nice to have a comment column or to be able to have alternate text to GPIO[#] in the utility so that the headers do not need to be edited after they are created to match what the GPIO signals are actually used for.

Ok, it's a great utility, but when drawing up the circuit board having done pin muxing, it would be really nice to be able to PRINT the result. The header files are completely useless to work out which mode you had which pins configured in, because PINCTRL237 in MD2 doesn't mean much to the average user.

It should also be noted that with a simple macro redefine, the files generated by the PinMux utility can directly used as StarterWare platform files.

1) Create pin mux design 2) Import mux.h and pinmux.h files into the platform directory your code is using. 3) Insert the following macro redefine into a new header file called by your code

//Macro redefine to allow starterware to directly use mux.h and pinmux.h files in the TI starterware platform build files

1. ifdef MUX_VAL //Redefine MUX_VAL defined by mux.h file (as generated by PINMUX utility

// for desired hardware configuration) to map to starterware calls

1. undef MUX_VAL
2. define MUX_VAL(OFFSET,VALUE)\

   HWREG( SOC_CONTROL_REGS + (OFFSET)) = (VALUE);

1. endif
