MCU pin overview

adamrakam — Thu, 09 Feb 2017 17:42:12 GMT

Hi,
I want to have an overview of all the pins for LPC11C24 and their exact functionality/capability(pull-up/down, I/O etc).

Is there eg an Excel file that contains all the information about the MCU pins ?

Thanks

I have successfully used the datasheet for exactly that: http://www.nxp.com/documents/data_sheet/LPC11CX2_CX4.pdf

And also the Users Guide: http://www.nxp.com/documents/user_manual/UM10398.pdf

I think you will find all the info in these ?

Thanks for the answer Carsten.

Yes, I know/knew about the info in the docs you mention. But I want to have this info in the form of a table in eg Excel. What I am about to do is to manually copy all the data from the PDF into Excel. So before I do that tedious job I ask if there is already such a table/ someone esle created it. I think I've seen this type of an overview in other manufacturers. And I suppose internally NXP must keep this info in the form I am looking for.

Hi Adam,

Please try using LPCXpert V3.2: PinMux and Software Configuration Tool for the LPC Families of Micro-Controllers

Please let me know if this helps.

Have a great day,

Thank you Sol,

very nice tool and there is a newer version 3.3

LPCXpert V3.3: Software Expert Tool for the LPC Family of Micro-Controllers

Not exactly what I asked for (excel table with the list of pins) but I did not know about LPCXpert and it is great but...

it seems as this tool does not work well for LPC11c24, I try to configure CAN and it does not work. Here:

Now I want to configure CAN pins and it is not possible. Anything I select from the drop down menu it will not be applied. Whatever I do it always stays like this :

And pins 19 and 20 (again CAN interface) are not available. When I go through the list of pins they are missing :

and when I press 'next' I get pin 21:

This tool seems to be incomplete or am I doing sth wrong ?

Thanks

CAN TX and CAN RX can not be relocated, they are fixed on pin 19 and 20.
