Hi everyone,I´ve got some problems  with compiling and uploading ArduCopter on Pixhawk. In the past I did some code modification and compiled with eclipse successfully. If I download arducopter,…Continue

Marvin,

I took a look at the thread you mentioned.  I can definitely help point you in the right direction on reading the raw serial data, but I've never tried writing to the SD card on the Pixhawk.  In the latest ArduCopter code, the developers have actually already used both Serial 4 and 5 for other optional purposes (a 3rd telemetry radio and a 2nd GPS receiver), so you're need to do a little code modification to re-purpose one of them for your usage.  It's pretty simple and straightforward.

Hi Marvin, 

Essentially the easiest way to do this is to use a pre-defined variable within the code to use as a way to log and transmit your data. What I did for my application was, use the variable "Sonar Range" and send the data through that variable via telemetry and also log it on the micro-sd on board. 

Do you know how to compile your own ardupilot code using MAKE. If not, you will have to learn that online because you will be changing the code quite a bit. If yes, you need to play around with the "user" files in the arducopter folder of the master software. 

I am a bit busy, later I will message you the files I used to log data. (my sensor was I2C based) so you will see that library being used.
