LPC1768,
pins
I created this because i wouldn't have the to look at the datasheet whenever I needed another pin, when making
PCB's. This is quite helpful (For me at least)
Feel free to copy and distribute. (Updated with mbed pins)

Nenad did it too, but in a IC like format, here
Nice! Maybe also add a column with mbed module pin numbers?
Consider it done!
Will update table soon as possible.
Regards,
Lerche

Updated with mbed pins :-)
And now what pins are interruptable.

Yes indeed very useful, you should stick it in the cookbook under the reference section!
Does anybody have a raw spreadsheet version of this table?

Christian,
Yes. That's exactly what I was looking for. I wanted it for tracking functions I'm hooking to the pins.
Thanks so much for the file.
I got a laminated card with the mbed that shows USB and ethernet pins which don't get mbed numbers.
1. like the LED mbed pins designations it would be good to add those here. It isn't immediately obvious which ones are the ethernet port/pin combos i.e. port 1_9 vs port 1_10.
2. do the ethernet pins have the possibility of other uses? I presume they could be DigitalInOut if they were defined in PinNames.h
, USBTX = P0_2 and USBRX = P0_3 are defined similar to the LEDx, and I suppose those are available if you are disconnected from the host PC. |
The blue colored P1.X, that is placed before the Grey colored ethernet states that you could use those as DigitalIn & Out.
The ethernet is connected through a PHY, so the LPC1768 itself, hasn't got direct connection to the outer pins on the mbed board.
If you look carefully, you'll see the LED designators in the lower left corner.

Error???
mbed Pin p7 Func4 says MAT3.1
According to schematic http://mbed.org/media/uploads/chris/lpc1768-refdesign-schematic.pdf it should be MAT2.1 !!!!
(If true then all 4 MAT's of counter2 are available. Hurray, hurray, hurray!)
I checked here: http://www.nxp.com/documents/data_sheet/LPC1769_68_67_66_65_64_63.pdf ( look at page 9, table 4)
LPC1768 chip pin78 (=mbed Pin p7) has MAT2.1
Make it easy to see what pins do what which is great. It also make it easy to see what pins DON'T come off of a MBED board. Looks like I'll have to go stright to my on PCB. Oh well.
I believe there is a mistake with pins 20 & 21.
Pin 20 is P1.31 and pin 21 is P1.30 - Function 1 - that's OK
Then Function 2 should be reserved.
Functions 2 & 3 become Functions 3 & 4 - That is AD0.4 and AD0.5 are function 4.

Hey could anyone tell me the connections to be made to interface an LCD....i have no idea as to which pins of the mbed board must be used for this
I found an error: p7/P0.7 should be MAT2.1, not MAT3.1
