Fork of mbed by mbed official

(01.May.2014) started sales! http://www.switch-science.com/catalog/1717/

(13.March.2014) updated to 0.5.0

This is a pin conversion PCB from mbed 1768/11U24 to arduino UNO.

So if you have both mbed and arduino shields, I guess you would be happy with such a conversion board :)

BIG changes from previous version

Ethernet RJ45 connector is removed.
1. http://mbed.org/components/Seeed-Ethernet-Shield-V20/ is the biggest hint to use Ethernet!
~~Most~~ ALL of components can be bought at Akizuki http://akizukidenshi.com/
1. But sorry, they do not send parts to abroad
Pinout is changed!

arduino	0.4.0	0.5.0
D4	p12	p21
D5	p11	p22
MOSI_	none	p11
MISO_	none	p12
SCK_	none	p13

This design has bug(s)

I²C functional pin differs between 1768 and 11U24.

Fixed bugs here

MiniUSB cable cannot be connected on mbed if you solder high-height electrolytic capacitor on C3.
1. http://akizukidenshi.com/catalog/g/gP-05002/ is the solution to make this 100% AKIZUKI parts!
the 6-pin ISP port is not inprimented in version 0.4.0
1. ~~it will be fixed in later version 0.4.1/0.4.2/0.5.0~~ This has beenfixed

I am doing some porting to use existing arduino shields but it may faster if you do it by yourself...

you can use arduino PinName "A0-A5,D0-D13" plus backside SPI port for easier porting.

To do this you have to edit PinName enum in

"mbed/TARGET_LPC1768/PinNames.h" or
"mbed/TARGET_LPC11U24/PinNames.h" as per your target mbed.

here is the actual list: This list includes define switch to switch pin assignment

Add pinmap NC terminators for LPC1768 CAN.

Update the license from MIT to Apache v2.

Make the semihost code target independent using opportune defines for the UID and MAC.
