Thanks man..just some doubts..
1) How the topic is getting linked to the uORB publishing/subscribing system ? Do I need to add the topic to any topic list or something ?
2) I'm sending the data serially to telem 1 in pixhawk and i can read the data from that port ( have written a code for that in the example section ). For publishing to the topic I can use the same code in modules with '#include ' header right ?
3) And for logging : " The list of logged topics can be customized with a file on the SD card. Create a file etc/logging/logger_topics.txt " , there is no etc folder on the SD card itself ! There is just the log folder . Does adding here will append the topics to the log file created when pixhwak is armed.
