Interactive Christmas Tree – DipCortex + WS2812B

It being almost Christmas I decided to decorate the family tree with some RGB LEDs but I wanted a bit more fun for myself and my two-year old daughter. So I used addressable RGB LED strip driven with a DipCortex. Which lets us set any LED on the strip to any colour.

To provide some interactivity I added a set of Red,Green and Blue arcade buttons. I set them up so my daughter can walk up to the tree and set off a colour, or mix of colours, spinning up the tree. Which as well as entertaining has been fun watching her mix the colours and shout out their names.

Normally controlling a large number of LEDs requires a number of LED driver chips and lots of control lines, The strips I am using on the tree have 360 LEDs and this is all controlled via one port pin. The LEDs themselves are also very tightly packed on to the strip and this is possible because the LED driver has been embedded in to the silicon of the LED. So you end up with a small four pin device that uses two pins for power, one for communication in and the last for communication out.

WiFi DipCortex Firmware Demo

Here is a quick video showing the current firmware for the WiFi DipCortex using the CC3000, It demonstrates connecting to an access point, resolving and pinging a hostname. Communicating over UDP to a PC and using smart config to configure the access point the WiFi DipCortex should connect too.

This firmware will be delivered with your WiFi DipCortex letting you (and us) test it out before you start having fun customising it for your application or writing your own code.

DipCortex is now mbed enabled

SolderSplash + ARM mbed

More exciting news, ARM have added support for our DipCortex platform to their mbed online compiler.

The ARM mbed team contacted us a month ago to talk about our DipCortex range with a view to expanding the mbed platform to support it. We got them a few of our prototype DipCortex’s and today they enabled it.

The big difference between mbed and other IDEs is that the compiler is online, you use it via your browser and your projects live in the cloud. This also has the advantage of there being many library’s for existing devices that shouldn’t require too many changes to get working, if any.

From today mbed users can now select which platform to build their code against, build the project which downloads a .bin file. This can then be dragged and dropped on to a DipCortex in boot mode.

Our next challenge is to port the CC3000 stack we have working with LPCxpresso to mbed. Stay tuned for more updates!

Pre-Order a DipCortex Now

For the past few weeks we have been overwhelmed with interest in our DipCortex range, to satisfy this we have searched for the best UK-based assembly company with the capabilities to produce our DipCortex modules in volume. We will be placing the order with our selected manufacturer next week.


DipCortex – Pre-Order Now

To ensure that people who are most interested get them first we are operating a pre-order system. Starting today you can secure a DipCortex for just £1. You are free to pre-order multiple boards if you like as well. You will receive an email with a link to our shop as soon as the boards are ready, letting you complete the purchase for your selected DipCortex. Estimated delivery time is currently 6 weeks.

The boards will go on sale priced at :

DipCortex M0 – £18 (£19 with header pins soldered)

DipCortex M3 – £22 (£23 with header pins soldered)

WiFi DipCortex – £35 (£36 with header pins soldered)

Your £1 will be deducted from this price. Shipping will be based upon your location and international shipping will be available. In the UK we charge the standard special delivery rate or uninsured first class post.

DipCortex – GPIO Intro Video and Guide

To help get you up and running and writing your own code for the DipCortex we have started our own GitHub repository, written a guide and uploaded a video.

Be sure to view at 720p so you can read the code!

This video takes you through the setup procedure, importing our codebase from GitHub, running through the code. Building it and boot-loading the bin file over the USB connection.

These guides are applicable for both the DipCortex’s and the up coming SolderBridges that use the same processors. We hope they are useful, if you have a preference for the subject of the next guide let us know!

DipCortex – ARM Cortex in a Dip Package with USB

This week we have been playing with another new product, the DipCortex. It’s an ARM Cortex M3/M0 in a 40 pin dip package and USB socket. It has two versions a NXP LPC1347 M3 and a LPC11U24 M0, the pin out roughly follows a certain range of 40pin 8bit micros.

It’s perfect for quickly prototyping a product on a bread board. Both have USB peripherals and a USB stack in ROM saving flash space. Updating the code can be performed by plugging it into the computer, holding both buttons and then releasing the reset button. A mass storage device then appears and firmware can be drag and dropped on to this drive. Press reset and the new code is executed. Have a look at the product page for more info.
