The official mbed C/C SDK provides the software platform and libraries to build your applications.
Fork of mbed by
(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.
- http://mbed.org/components/Seeed-Ethernet-Shield-V20/ is the biggest hint to use Ethernet!
MostALL of components can be bought at Akizuki http://akizukidenshi.com/- 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.
- 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
it will be fixed in later version 0.4.1/0.4.2/0.5.0This 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
part_of_PinNames.h
