It has been quite a long time since an update. We have been busy with exams and other school related stuff.

In the coming couple of weeks we will focus on bug fixing and improving existing libraries and tutorials. With the help of some Simplecortex users a few bugs have popped up and some tutorials need a good check to get them up to date. We also tested CoIDE 1.7.0 and it seems a lot more stable the 1.5.1. To start a new project is a bit different but it speaks for itself really. Give it a try :)

Happy new year!

Welcome to 2013 from the Simplecortex crew.

Time for a new year with much more cool projects, software and hardware. We hope everyone still has all 10 fingers left :)

Update time

More LCD library news, it is now faster. We are testing a new LCD driver that is about 8 to 10 times faster then the old shield. It only uses IO pins from the 22 pins connector next to the Ethernet connector so it is possible to use a shield and an LCD at the same time. At the moment it uses an LCD like this and loads of jumper wires, we are working on a small PCB for it. Somewhere in the following days the code and schematic on connecting the LCD will be posted in the repository.

We tested CoIDE 1.6.0 for a while but we experienced quite some bugs. For now we would recommend Simplecortex users to keep using 1.5.1 instead of 1.6.0. When a bugfix is rolled out we will give it another go. With holidays coming we got enough to do, finances from the first year of BRC Electronics for example :)

Assuming the world will still be here at 22 December we will keep you up to date.

A small update this time.

As all three people behind the Simplecortex are all students we still have exam week which costs quite some time. We did manage to update the LCD library a bit.

The LCD library now supports landscape mode and the touch input is improved a bit. The updated library can be found in our repository and the tutorial will be changed. We will be working on the Logic analyser as well as getting support for our CMSIS-DAP debugger in CoIDE. They now support the CMSIS-DAP for Freescale microcontrollers and ours will hopefully follow soon.

We noticed that CoIDE 1.6.0 is not compatible with our tutorials for CoIDE. We will update them in the following month. Untill then you can keep working with CoIDE 1.5.1 or try 1.6.0 if you dare ;)

As promised, the second part of the update.

For a while now we are working on a new cool project, a cheap logic analyser. The new LPC4300 series from NXP has a very cool and unique peripheral called SGPIO or Serial GPIO. These are a handful IO pins that can be used to easily create extra serial protocols like I2C or SPI. It is possible to do this in software on every microcontroller but it's quite a big CPU load. SGPIO uses a 32 bit buffer per channel to lower this CPU load a lot. This is also a very nice peripheral to make a logic analyser with without using a FPGA. Add the fairly large 264K SRAM on the LPC4300 series and the idea for a logic analyser was born. If you don't know what a logic analyser is this video can explain it quite well.

This is still a project in development and it is not done yet, this is just a post to inform you and see if people would be interested in it.

When done the whole project will be open source. It used the well known and powerful OLS software for the PC and will be compatible with the SUMP protocol. We aim for the following specifications:

16 channels

50+ Mhz

96K samples using 16 channels

35 euro price.

If you would be interested in this send us an mail or post a reply on this blog, if there is enough interest we will finish the project ASAP. We also need a cool name, suggestions are very welcome.
