Re: [Paparazzi-devel] On board data logging using TWOG

[Christoph Niemann]

Hi guys,

last year I had a similar problem. I solved it by using an OpenLog from Sparkfun. Thats less expensive than a second AP and is smaller as well. I hooked it into the UART lines for the Radiomodem. I wrote a simple module, you can find it here: https://github.com/chni/paparazzi/tree/master/sw/airborne/modules/openlog .
It just includes a timestamp into the datastream every 500ms. Then to extract the data, I wrote a small tool that an be found here https://github.com/chni/paparazzi/blob/master/sw/logalizer/openlog2tlm.c - It creates TLM files and you can proceed like described in http://paparazzi.enac.fr/wiki/Data_Logger

Cheers

I am trying to use the sparkfun logger (the one with the LPC2148).

I haven't been able to make it work so far but it shouldn't be so difficult (but I could install the paparazzi bootloader).

Maybe the guys with a better knowledge of the code might help me a little here.

Should I define a new board ? I need for instance to redefine the led pins…

Any help appreciated.

Cédric

Objet : [Paparazzi-devel] On board data logging using TWOG

 

Hi,
  I have  few doubts regarding paparazzi AP
1) Please tell me how to do on board data logging when I am using paparazzi TWOG Autopilot board on my Micro Aerial Vehicle? I believe people might have already done this exercise. I know the Umarim board comes with a data logger but In case if i am using any of the tiny board what are the feasible options for on board data logging? Anybody please help me out.

2) I wanted to measure the motor/Propeller RPM, from the Internet I found Eagle tree has one Brush less RPM sensor to measure the motor/Propeller RPM, Does paparazzi board has provision to accept this RPM sensor measurement as Input? If yes how to do that?
