Hi Heinrich.
"All" you need to do is write a new board makefile in conf/boards and a new board header file in sw/airborne/boards containing the pin mapping you wish. You can use the Lisa m ones as example and starting point.
Cheers, Felix
MichelYou should order new hands :)40h ?!?!? for one board ???The construction of a prototype by hand need about 40h.
Kidding aside, i'm not sure to get your message : if you want to port pprz on "cheap" hardware, ok, " just do it", but don't confuse people with bad numbers.
I think having companies taking the risk building the hardware that is perfectly matching our needs is a real chance...

Hi Michal,
a problem with the Paparazzi project is that the hardware is expensive by the low count of units for example for many students and hobbyists.
The special hardware like Krooz, Apogee etc. is good but not available in many countries or shops and make also
a determination between mutirotor or normal wings aircraft
For example the production of our one autopilot HBmini the self cost of manufacturing a set of 10 units is about 2500 Euros.
The fix cost of a production run is about 1000 Euros in Germany .
The construction of a prototype by hand need about 40h.
The second idea is to use the same cheap hardware for simple software like MultiWii and a more complex like Paparazzi.
This gives the chance that a hobbyists starts with the simple software and can chance to Paparazzi to a second without new hardware.
The work for the implementation is only the addition of a new make system and directories.
Regards
Heinrich

With kind regardsHello Heinrich,do I understand correctly that you want to port paparazzi onto an existing hardware? I noticed that recently lot of new APs came out (Krooz, Apogee) and the community is working on those. Just a suggestion - maybe it would be better to first finish and properly test those boards (so they can be considered airworthy) before moving to new hardware (which should be way easier with proven drivers)?

_______________________________________________Hi,
i want to start a discussion for low cost STM3 autopilots to use with paparazzi
I have flown a low cost Multikopter with the following autopilot with the STM32f103 (M3 with 48 pins 128kB EPROM 20kB RAM):
http://flyduino.net/Multikopter-FC_2 cost 47 Euro compatible with
http://abusemark.com/store/index.php?main_page=product_info&products_id=30
(cost 49,50 Euro) compatible with
http://abusemark.com/store/index.php?main_page=product_info&products_id=45
( Cost 18,50 Euro without magnet and baron sensor).
The multirotor has the same performance, like my paparazzi multirotor.
The software is a 32-bit MultiWii port.
The hardware is full Paparazzi computable.
The board has a USB connection and sensors of the sate of the art.
It seems to be simple to port paparazzi on this hardware. The only restriction is the 128KB EPROM space.
Is same one of the Paparazzi team willing to work with me to port paparazzi on this hardware?
Next time STM offer a processor with 265KB EPROM and 64 KB RAM in the same housing with the f4 CPU (floating point unit, cost about 10 Euros).
I am locking for answers
Heinrich
