mbed Cookbook Community Wiki

Welcome to the mbed Cookbook, a wiki for publishing user-contributed libraries and resources. This is the community "Handbook" for all the useful component and library building blocks that can be reused to cook up your prototypes.

Please feel free contribute component libraries, building blocks and any reference that could be reused. If you see ways to improve existing resources with extra examples, explanations or insights, please jump in!

What is the difference between the LPC2368 & LPC1768,

the only thing i can find is LPC1768 appeas to have more code examples for USB !

I was looking for something a bit more in a baseboard than the proto-strips and what is currently available, so put together this schematic and initial layout concept (note the version 0.01 designation). Population changes, and either headers or jumper wires provide some flexibility. Would such a design be of interest to others? /media/uploads/WiredHome/mbed_breakout board sch v0.01.pdf /media/uploads/WiredHome/mbed_breakout board pcb v0.01.pdf

How do I add a library to this page?\

user Simon Ford

Hi William,

Assuming you are logged in, you can just edit the homepage to add a link. To create a new page, you just enter a new page name in the url as you'd expect it; see About the Cookbook

The LPC1768 is based on the Cortex M3 core whilst the LPC2368 is based on the ARM7 classic core. This is the major difference.

Does anyone have a schematic for converting a 10baseT to 10base2? I need this for a project I'm developing as it only communicates to an old vintage hardware via a coax connection. I know there are boxes you can buy that do the conversion, but they are expensive and I'd rather put the circuitry within my project.

user Lee Archer

Does anyone know if there is a faster way to access the analogin port other than using the Analogin library? The problem is that (using the Timer function) the fastest conversion I can get is 72us. The LPC1768 can sample upto 200Khz and I would like to use it at full speed for an oscilloscope. Would it be a matter of writing my own library routine or may I have to go to assembler? Any ideas would be most greatfully received.

user Dimiter K

Use the forum for these questions. If you search there is another modified AnalogIn lib. The other solution would be to write or adapt the driver yourself , look at the CMSIS package.

How to run open os using mbed? lik Android, mee go ..

user test test

Hi, We want to realize transfering the CAN message through USB. It seems that we cannot find the library of USB as Device. If we try to realize the transfer function,could you give me some advice? Thank you & best regards.

This project is about taking mbed another step up by using it with SOFT PLC's, so that mbed works as an I/O Card that serve the Soft PLC software on computer, i used a famous Soft PLC Wonderware Incontrol , but you can use the same software with any Soft PLC product that support DDE Connection to the I/O Card Drivers

i require a program to demonstrate how to make lpc1768,capture the serial output from 10:1 SN65lv1023ADB serialiser from texas instruments.and report it through USB

Hi! I can't find the library for the accelerometer ADXL335, only for ADXL345, but this doesn't work. Does anybody know where I can get this library? Or is there a different way to program this accelerometer? Thanks.

user Elmicro Computer
18 Jul 2012

Hi Tanja,

the ADXL345 delivers its axis values using digital interfaces (SPI or I²C). The ADXL335 offers three analog values which can easily be sampled by using the mbeds analog inputs. It operates at 3,3V.

So just connect the breakout board (you have the Sparkfun board, I assume?) to VOUT, GND and then A1/2/3 each to an analogue input. Use the AnalogIn function of the mbed library.

Start by periodically outputting the three axis' values via printf through the virtual serial port (use e.g. the freeware "HTERM" for displaying the output on your PC).

Happy developing! Stefan.

Thank you, it works now :)
