Getting Started With The DipCortex

DipCortex’s have begun to arrive around the world over the last week we have fulfilled orders going to every continent. So the first question is how do you use it! which means getting your own compiled code on to it. The DipCortex uses a mass storage boot loader (acts like a memory stick) that is built in to the processor. To activate it you hold the boot button while plugging in a USB cable connected to a PC or hold the boot button while resetting it. The DipCortex then appears as a new drive on your PC, to change the firmware delete the firmware.bin, replace it with your own and reset it. Once reset it will then start executing your new code.

DipCortex Mass Storage Boot Loader

Writing code for the first time for a new device has a learning curve, starting off small is a good first step and one of the simplest things you can do with any micro controller is use it’s GPIO. For that we have a guide and a video which will get you up to speed with controlling the GPIO using LPCxpresso. Using mbed is even easier as they add a HAL (hardware abstraction layer) that makes controling any mbed supported platforms GPIO the same, this example shows you how to toggle the LEDs.

Moving on from there we have a growing list of examples on our mbed page which include using the USB connection as a serial port and streaming ADC data to the PC. For those of you with a WiFi DipCortex we have a large demo that shows you how to connect the CC3000 module to a network and implement UDP, TCP, NTP, HTTP Get, HTTP Put and Websocket. I hope to create a few more specific demo’s next to show you how you might create your next internet connected device.

Our forum also has more info, FAQ’s and links to other examples. Also drop us a message and let us know what your making, we will try to help where we can and show off your project on the blog as well.

At the end of the week we hope to release the remaining stock to people who have pre-ordered after the release of the first batch and those that filled in the stock request form. It does look like we will need to order another batch which is very good news!

DipCortex, Software examples and more

A few weeks ago, Martin Kojtal contacted us about working together to create a complete library for the CC3000 on the mbed platform. One that could be used with existing mbed library’s. He assembled a small team of developers with a similar goal and this week we are ready to share it with the world. The library is fully working on the WiFi DipCortex and there are many demos available that demonstrate how you can write your own applications using the WiFi Dipcortex.

We have put together an mbed cookbook that list the demo’s and shows you how to configure them, these include TCP server/client, UDP server/client, Websocket, HTTP client and Twitter client. Specifically for the DipCortex I am putting together an example that brings them all together in a similar way to the standalone C example project I shall be sharing does. I call this my kitchen sink project.

For those of you that prefer to work in an offline IDE and get a little closer to the bare metal, I will be posting my LPCXpresso C project to GitHub in the next few days here. This example shows you how to configure the CC3000 modules and again set UDP/TCP clients and servers. It also adds in the USB CDC support so that an external serial to USB convertor is not required. You can see an earlier version of this software in my video.

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.

WiFi DipCortex – An embedded WiFi module to power your next product

WiFi is something we have wanted to do for a long time, but there are a lot of technical and regulatory challenges around it. If you’re running an OS on an embedded PC like the Raspberry PI, WiFi is simple, you buy a cheap dongle and the intelligence is in the driver.

For a low power embedded project where you’re not running an OS it gets a lot harder and that means it’s expensive. So the only real option is to use a WiFi module and these are normally expensive.

A few months ago, whilst designing the DipCortex, we identified a module that is low cost and comes with FCC, IC & ETSI certification, saving huge costs assocaited with getting radio equipment through testing. The goal was to squeeze this module, the TI CC3000MOD, on to a board the same size as the DipCortex which was a massive challenge, as the DipCortex is sized to replace a 40pin DIP package.
