Ardu Hardware Roadmap

Started this discussion. Last reply by Chris Anderson May 25, 2011. 9 Replies

In reference to the comments in "DIY Drones team at Maker Faire" posting, I will start a new discussion about the future of Ardu Hardware Development.I think it is time for a more powerfull processor…Continue

Hi Thomas,

Here is the Schematic of my board. I hope it will be helpful for you.
It will be interesting to hear some comment of you about the schematic.

Regards.

Hi Thomas,

Thanks for the advices, I will improve this on the next version! =)
it looks more familiar to me  the topology that is in the first link.in the second link, it looks more simple but... I never saw that kind of topology.
Tell me... which schematic. are you going to base your design?

Using JTAG without an Emulator, it's painful. that it true! 
I'm using the Code Composer Studio IDE from Texas Instruments, it's based on Eclipse too.

Regards.

Hi Juan,

 

Yes, the second sheet is .. mmhh.. very compact  :)

It is the sheet of the flightcontrol of Mikrokopter (www.mikrokopter.de). An 8 bit cpu based system which works very well/stable. That's why I took this as example.

My starting point of development was the project of Bill Nesbitt (http://www.diydrones.com/profiles/blogs/autoquad-ver-5) which is based on a STM32F103. After porting the main board, I became aware of the project of Roberto Navoni which is based on the same cpu series. He took some existing software together, improved them, and now you can run the ardupirates ng software on it. (http://www.virtualrobotix.com/page/multipilot32-1)

So now I'm playing with this cpu board and the standard oilpan imu, works well (http://www.youtube.com/watch?v=mT4BpqDvx-w). So the next step might be to port the sensor board of autoquad v5 for the MP32.

So I try to get (step by step) familiar with all the needed sensor,cpu programming and filter stuff :)

By the way, why you decided to use the texas cpu? Working with it before?

 

regards 

Thomas
