Devin Braatz posted a discussionDM X serial to PPM
Hi, I am attempting to have a spektrum DX6i controller communicate with my APM 2.5 board for a hardware in the loop simulation/ actual flying. However, after looking in the forums and such I could not find a way to convert the serial that the transmitter receives into the PPM that The APM 2.5 needs. Can anybody help??Devin BraatzSee More

The MP connects to my plane using TCP. The serial converter forward whatever content coming from the APM yes. I configure the serial converter as a server. I have also tried to setup for UDP and that works fine as well."

Welcome to DIY Drones!
This is the home for everything about amateur Unmanned Aerial Vehicles (UAVs). Use the tabs and drop-down menus above to navigate the site. (About us/Site rules)
This community created the Arduino-based ArduPilot, the world's first universal autopilot (planes, multicopters of all sorts and ground rovers). The APM 2.5 autopilot hardware runs a variety of powerful free UAV software systems, including:
- ArduPlane, a pro-level UAV system for planes of all types
- ArduCopter, a fully-autonomous multicopter and heli UAV system
- ArduRover, a fully-autonomous ground-based vehicle system
I'm new to all this--where do I start? Are amateur UAVs legal? (yes)

My quad is flying better than it should. I almost feel guilty.
I slapped together a frame in a few hours. I use cheap props mounted on long shafts with cheap collets. The motors are not precisely aligned to the frame. The props are not balanced perfectly. Motor centers form a rectangle not a square. APM is strapped to the frame. I never bothered to calibrate compassmot. CG is not in the center of the…

In this post I’ll describe how to make your own cable to trigger the Samsung mirrorless cameras NX20, NX210 and NX1000. We’ll be using an ArduPilot Mega 2.5 to do the triggering but you can use any Arduino or even a soldered push button.
