Hi, when i plug in IMU to Mega the system seems to work, but when i go into testmode and read the data i dont get any results. Looks like the Mega isnt getting any data from IMU (Gyro and Accel),…Continue
"Good news, i found the kernel modules needed for my 10" tablet, now it recognizes the APM and creates a serial port node in /dev. I can get output as well :)
So if you dont get a connection or no output try to look up the kernel modules or if…"
"Ok i found a new problem. When i connect the APM to my cheap 7" tablet it recognizes the APM an creates the ttyACM0 node that i can read from. But when i use my 10" tablet it recognizes the APM, but does not create a…"
"I made an app with android API 7 which is 2.0 i think and the maps API worked pretty well. Unfortunately bluetooth functions are pretty restricted there. Guess you are right, most cheap china tablets supprt android 4 anyways. Poor guys with older…"
"Ok just had a look at this from adb shell. Looks like android recognizes the APM as serial device. I get output like this:

"Every china tablet with USB should work. I think the description has to say USB OTG to have USB support like mouse and keyboard. If this works the APM should get power too.
But does it work with USB? You need drivers and i dont know if you can…"
"What is the level converter for? The IMU board has 5v input, so use it, no need for a level converter. SDA and SCL need to be connected to A4 and A5 (have a look at http://arduino.cc/en/Main/ArduinoBoardUno). Rest looks ok so far."
"You can only fly as far as your video still works. In the distance antennas have a pretty big corridor where you can fly in wothout adjusting them directly to the plane. So even if only one of the 25 video frames per second has valid data it should…"
"This is nice, but not what Boris meant. You read the data with your computer from the video, but he meant to transfer data through hidden video lines, so you can use a microcontroller or a ground control station to read it without laptop on the…"
"Looks like your servo code is not quite right. The servos move much smoother with the rc control than with your phone. Looks like there is a timing issue, had that with my DIY headtracker too. Do you use ~50hz as frequency for PWM calculations? I…"
"Not yet, i really just started. But i can tell you this: We have some kind of ground station and we want to use the MinimOSD to add telemetry data to the video stream. Groundstation will have some special features you'll like too ;). We already…"
