Flight Controller Output Signal at Way Point

Hi there,I was wondering if anyone mind please sharing some ideas on how to have the Pixhawk output a signal/voltage from one of its output pins when a waypoint is reached?The purpose of this is to have the flight controller trigger a sequence of actions on the Arduino that is also mounted on the UAV.All inputs are greatly appreciated.Thanks,BruceSee More

"HI there, Your work is very interesting and I was wondering if you mind please sharing how you are extracting the units of time after you convert your dataflash log file into MATLAB?  Thanks"

"Hi Andre, Thanks for your help. I managed to export the data to MATLAB using the "Create MATLAB File" feature in Mission Planner. However, I was wondering if you knew what units the "Time US" parameter is in? Thanks"

"Hi Andre,  Thanks again for your help. Would you mind please elaborating a bit more on how to use mavlogdump.py? Specifically, I am confused about how to provide the input BIN file, and where I can find the output file. Thank you for your help…"

"Thanks Ultrafuge, Although I might be doing something wrong, because it seems like on my plot all the time stamps remain at 0?"

"for MATLAB/ python use mavlogdump.py to dump the log in a decent way.  (install mavproxy if you don't have it yet.) For analysis/browsing the log, use the best tool; APMPlanner2."

Data Flash Log - Line Number to Seconds

Hi there,I was wondering if someone mind please explaining how to change the x-axis to have units of time (seconds,milliseconds, etc.) when graphing/exporting Data Flash Logs in Mission Planner. Currently, Mission Planner's Data Flash Log browser plots the value selected vs line number by default, but how do you determine how much time has elapsed between each line number?Ultimately I would like to analyze this data in MATLAB or Python, and any input is greatly appreciated.Thank you for your…See More
