Re: [Paparazzi-devel] Problem with TLM file decoding

[Zhang Qiuchen]

Hello everybody~

My name is Autumn and I'm trying to write telemetry data to an SD via a TWOG 
board (which is connected to the main autopilot board Tiny v2.11 via UART).
When the data is written into the SD card, it is written in a compressed from 
and results in a TLM file. The executable file in sw/logalizer/sd2log can 
decoding the TLM file and generate a simple data file. However, when I tried to 
write telemetry file into the SD card, I cannot decode the TLM file and the 
error msg was "Fatal error: exception Failure("Pprz.values_of_payload, too many 
bytes:". As far as I can imagine, the data format which the decoder expects 
depends on the message id, and there must be somewhere in the code that 
specifies this expected format. Does anybody know where this information is 
located? And can I modify it in order to enable decoding of arbitrary format of 
data ?

Thank you very much! Please reply me if you need more clarification of the 
situation!!
