The official mbed C/C SDK provides the software platform and libraries to build your applications.

Dependents: SeeedTouchLCD

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
