[Paparazzi-devel] IMU, jeti and SD logger

[Cédric Marzer]

Hello,

 

I have been flying paparazzi stuff for a few years but only with the basical LPC2148 tiny boards and IR sensors.

I am planning to try to develop a plane easier to put in flight with just the minimum to run its task namely to take pictures for  surveying work.

 

My idea is to get rid of the modem and the GCS and use the jeti receiver for the RC link, the uplink and the downlink and make something more basic that only uses the two lines of the jeti box lcd and its 4 buttons. Does anyone of you have tried to interface a tiny with a jeti receiver and use its telemetry ?

 

The other idea is to use an onboard sd card to record the flight. If I remember well, someone has used a dedicated tiny to do that task. I guess a dedicated microcontroller is necessary because of the time it takes to write on the sd or am I wrong ?

 

The last idea is to replace the ir sensor with an IMU. I know that many people have worked on it, but it is difficult to understand which system is the more mature so far. Remember I am ok with the LPC2148 and I don't necessary want to explore other microcontrollers unless there is a very good reason for it.

 

Thank you in advance for your messages.
