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

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

  1. Ethernet RJ45 connector is removed.
    1. http://mbed.org/components/Seeed-Ethernet-Shield-V20/ is the biggest hint to use Ethernet!
  2. Most ALL of components can be bought at Akizuki http://akizukidenshi.com/
    1. But sorry, they do not send parts to abroad
  3. Pinout is changed!
arduino0.4.00.5.0
D4p12p21
D5p11p22
MOSI_nonep11
MISO_nonep12
SCK_nonep13

This design has bug(s)

  1. I2C functional pin differs between 1768 and 11U24.

Fixed bugs here

  1. 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!
  2. 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

        USBRX = P0_3,
