I am just about to start doing some development work on the CAN bus as part of my project and I have looked through the source and the documentation. It seems that the supplied libraries don't allow me to control the sampling position based on the actual CAN bus I am running and instead accepts only...

I actually find that with the low cost of PCB's these days it is far easier to design a prototype PCB instead of trying to do designs on protoboards. I even design a prototype PCB before that plugged into the DEV board and after this was tested I did the final PCB design. By the time I purchased ada...

Just a quick update. I went with a semaphore for accessing the linked list. Because of the way the system works and the main task only needing to add to the list on user input, the speed was not important so I just set the semaphore when I want to add or read from the list. So far it has been workin...

Hi Liam, If you always use Netburner hardware then you don't pay any license fee. Just the initial cost of the development system and then as many modules as you want. If you want to do your own hardware then they charge a license fee and this is way beyond hobby cost at around $30,000. They can als...

Hi Tod and RG, The wireless task is actual over a UART to a SIM20 module so there is no TCP. The display task is running much slower processing the touchscreen and the dispay update so I have this wireless task running on it's own handling that part of the system. All it has to do is send out the re...

Hi all, I have an application with a number of tasks and 1 of the tasks is setup to handle the touch screen and dislay the graphics. One of the other tasks handles a wireless communications link. The wireless task simply sends out requests to another device that sends back resonses. The task has a s...

As far as I can tell, that is how the license agreement with Netburner works. You purchase the initial development system and this gives you the code to programme those devices and you are then free to order as many bare boards as you need and no royalties as purchasing the boards entitles you to th...

Your only downside is that the 30WQ04FN is SMD but you should be able to fit it on the current boards and rework for a revision for later.

Hi Sam, I use the following for the same Nat Semi device. 30WQ04FN This is a 3.5A device and less likely to fail if you draw more than 1A which is likely with the 1N5817. My old designs used that and it was also failing due to shorts or excess current. I have had no issues since switching to the 30W...

Good that it is 3.3V as the data rate is 4Mbit/s which means fast edges and the potential dividor ideal would not be ideal there and possibly the transistor idea too.

Be interested to see how you get on with this and how is pans out.! Keep us posted?
